Contact tracing is an important method for health authorities to determine the source of infection and to prevent further transmission. The use of location data from mobile phones by governments for this purpose has prompted privacy concerns, with Amnesty International and more than a hundred other organisations issuing a statement calling for limits on this kind of surveillance.
Several mobile apps have been implemented or proposed for voluntary use, and as of 7 April 2020 more than a dozen expert groups were working on privacy-friendly solutions such as using Bluetooth to log a user's proximity to other cellphones. (Users are alerted if they have been near someone who subsequently tests positive.)
On 10 April 2020, Google and Apple jointly announced an initiative for privacy-preserving contact tracing based on Bluetooth technology and cryptography. The system is intended to allow governments to create official privacy-preserving coronavirus tracking apps, with the eventual goal of integration of this functionality directly into the iOS and Android mobile platforms. In Europe and in the U.S., Palantir Technologies is also providing COVID-19 tracking services.
Increasing capacity and adapting healthcare for the needs of COVID-19 patients is described by the WHO as a fundamental outbreak response measure. The ECDC and the European regional office of the WHO have issued guidelines for hospitals and primary healthcare services for shifting of resources at multiple levels, including focusing laboratory services towards COVID-19 testing, cancelling elective procedures whenever possible, separating and isolating COVID-19 positive patients, and increasing intensive care capabilities by training personnel and increasing the number of available ventilators and beds. In addition, in an attempt to maintain physical distancing, and to protect both patients and clinicians, in some areas non-emergency healthcare services are being provided virtually.
Due to capacity limitations in the standard supply chains, some manufacturers are 3D printing healthcare material such as nasal swabs and ventilator parts. In one example, when an Italian hospital urgently required a ventilator valve, and the supplier was unable to deliver in the timescale required, a local startup received legal threats due to alleged patent infringement after reverse-engineering and printing the required hundred valves overnight. On 23 April 2020, NASA reported building, in 37 days, a ventilator which is currently undergoing further testing. NASA is seeking fast-track approval.
Based on the retrospective analysis, starting from December 2019, the number of COVID-19 cases in Hubei gradually increased, reaching 60 by 20 December and at least 266 by 31 December.
On 24 December 2019, Wuhan Central Hospital sent a bronchoalveolar lavage fluid (BAL) sample from an unresolved clinical case to sequencing company Vision Medicals. On 27 and 28 December, Vision Medicals informed the Wuhan Central Hospital and the Chinese CDC of the results of the test, showing a new coronavirus. A pneumonia cluster of unknown cause was observed on 26 December and treated by the doctor Zhang Jixian in Hubei Provincial Hospital, who informed the Wuhan Jianghan CDC on 27 December.
On 30 December 2019, a test report addressed to Wuhan Central Hospital, from company CapitalBio Medlab, stated that there was an erroneous positive result for SARS, causing a group of doctors at Wuhan Central Hospital to alert their colleagues and relevant hospital authorities of the result. Eight of those doctors, including Li Wenliang (who was also punished on 3 January), were later admonished by the police for spreading false rumours; and another doctor, Ai Fen, was reprimanded by her superiors for raising the alarm. That evening, the Wuhan Municipal Health Commission issued a notice to various medical institutions about "the treatment of pneumonia of unknown cause". The next day, the Wuhan Municipal Health Commission made the first public announcement of a pneumonia outbreak of unknown cause, confirming 27 cases—enough to trigger an investigation.
The following day, on December 31, the WHO learned about a cluster of viral pneumonia cases of an unknown cause in Wuhan. An investigation was launched at the start of January 2020.
According to official Chinese sources, the early cases were mostly linked to the Huanan Seafood Wholesale Market, which also sold live animals. However, in May 2020, George Gao, the director of the Chinese Center for Disease Control and Prevention, said animal samples collected from the seafood market had tested negative for the virus, indicating the market was not the source of the initial outbreak.
During the early stages of the outbreak, the number of cases doubled approximately every seven and a half days. In early and mid-January 2020, the virus spread to other Chinese provinces, helped by the Chinese New Year migration and Wuhan being a transport hub and major rail interchange. On 10 January, the SARS-CoV-2 genetic sequence data was shared through GISAID. On 20 January, China reported nearly 140 new cases in one day, including two people in Beijing and one in Shenzhen. A retrospective official study published in March found that 6,174 people had already developed symptoms by 20 January (most of them would be diagnosed later) and more may have been infected. A report in The Lancet on 24 January indicated human transmission, strongly recommended personal protective equipment for health workers, and said testing for the virus was essential due to its "pandemic potential".
On 30 January 2020, with 7,818 confirmed cases across 19 countries, the WHO declared the COVID-19 outbreak a Public Health Emergency of International Concern (PHEIC), and then a pandemic on 11 March 2020 as Italy, Iran, South Korea, and Japan reported increasing numbers of cases.
On 31 January 2020, Italy had its first confirmed cases, two tourists from China. As of 13 March 2020, the WHO considered Europe the active centre of the pandemic. On 19 March 2020, Italy overtook China as the country with the most reported deaths. By 26 March, the United States had overtaken China and Italy with the highest number of confirmed cases in the world. Research on coronavirus genomes indicates the majority of COVID-19 cases in New York came from European travellers, rather than directly from China or any other Asian country. Retesting of prior samples found a person in France who had the virus on 27 December 2019 and a person in the United States who died from the disease on 6 February 2020.
On 11 June 2020, after 55 days without a locally transmitted case being officially reported, the city of Beijing reported a single COVID-19 case, followed by two more cases on 12 June. As of 15 June 2020, 79 cases were officially confirmed. Most of these patients went to Xinfadi Wholesale Market.
On 29 June 2020, WHO warned that the spread of the virus was still accelerating as countries reopened their economies, despite many countries having made progress in slowing down the spread.
On 15 July 2020, one COVID-19 case was officially reported in Dalian in more than three months. The patient did not travel outside the city in the 14 days before developing symptoms, nor did he have contact with people from "areas of attention."
In October 2020, the WHO stated, at a special meeting of WHO leaders, that one in ten people around the world may have been infected with COVID-19. At the time, that translated to 780 million people being infected, while only 35 million infections had been confirmed.
In early November 2020, Denmark reported on an outbreak of a unique mutated variant being transmitted to humans from minks in its North Jutland Region. All twelve human cases of the mutated variant were identified in September 2020. The WHO released a report saying the variant "had a combination of mutations or changes that have not been previously observed." In response, Prime Minister Mette Frederiksen ordered for the country – the world's largest producer of mink fur – to cull its mink population by as many as 17 million.
On 9 November 2020, Pfizer released their trial results for a candidate vaccine, showing that it is 90% effective against the virus. Later that day, Novavax entered an FDA Fast Track application for their vaccine. Virologist and U.S. National Institute of Allergy and Infectious Diseases director Anthony Fauci indicated that the Pfizer vaccine targets the spike protein used to infect cells by the virus. Some issues left to be answered are how long the vaccine offers protection, and if it offers the same level of protection to all ages. Initial doses will likely go to healthcare workers on the front lines.
On 9 November 2020 the United States surpassed 10 million confirmed cases of COVID-19, making it the country with the most cases worldwide by a large margin.
It was reported on 27 November, that a publication released by the Centers for Disease Control and Prevention indicated that the current numbers of viral infection are via confirmed laboratory test only. However, the true number could be about eight times the reported number; the report further indicated that the true number of virus infected cases could be around 100 million in the U.S.
On 14 December 2020, Public Health England reported a new variant had been discovered in the South East of England, predominantly in Kent. The variant, named Variant of Concern 202012/01, showed changes to the spike protein which could make the virus more infectious. As of 13 December, there were 1,108 cases identified. Many countries halted all flights from the UK; France-bound Eurotunnel service was suspended and ferries carrying passengers and accompanied freight were cancelled as the French border closed to people on 20 December.
On 2 January, VOC-202012/01, a variant of SARS-CoV-2 first discovered in the UK, had been identified in 33 countries around the world, including: Pakistan, South Korea, Switzerland, Taiwan, Norway, Italy, Japan, Lebanon, India, Canada, Denmark, France, Germany, Iceland, and China.
On 12 January, it was reported that a team of scientists from the World Health Organization would arrive in Wuhan on the 14th of the month; this is to ascertain the origin of SARS-CoV-2 and determine what were the intermediate hosts between the original reservoir and humans. On the following day, two of the WHO members were barred from entering China because, according to the country, antibodies for the virus were detected in both.
On 25 January, the Brazil variant was detected in Minnesota.
On 29 January, it was reported that the Novavax vaccine was only 49% effective against the 501.V2 variant in a clinical trial in South Africa. The China COVID-19 vaccine CoronaVac indicated 50.4% effectivity in a Brazil clinical trial.
As of 5 March 2021, more than 116 million cases have been reported worldwide due to COVID-19; more than 2.57 million have died and more than 65.5 million have recovered.
A total of 192 countries and territories have had at least one case of COVID-19 so far. Due to the pandemic in Europe, many countries in the Schengen Area have restricted free movement and set up border controls. National reactions have included containment measures such as quarantines and curfews (known as stay-at-home orders, shelter-in-place orders, or lockdowns). The WHO's recommendation on curfews and lockdowns is that they should be short-term measures to reorganise, regroup, rebalance resources, and protect health workers who are exhausted. To achieve a balance between restrictions and normal life, the long-term responses to the pandemic should consist of strict personal hygiene, effective contact tracing, and isolating when ill.
By 26 March 2020, 1.7 billion people worldwide were under some form of lockdown, which increased to 3.9 billion people by the first week of April—more than half the world's population.
By late April 2020, around 300 million people were under lockdown in nations of Europe, including but not limited to Italy, Spain, France, and the United Kingdom, while around 200 million people were under lockdown in Latin America. Nearly 300 million people, or about 90 percent of the population, were under some form of lockdown in the United States, around 100 million people in the Philippines, about 59 million people in South Africa, and 1.3 billion people have been under lockdown in India. On 21 May 2020, 100,000 new infections occurred worldwide, the most since the start of the pandemic, while overall 5 million cases were surpassed.
As of 30 April 2020[update], cases have been reported in all Asian countries except for Turkmenistan and North Korea, although these countries likely also have cases. Despite being the first area of the world hit by the outbreak, the early wide-scale response of some Asian states, particularly Bhutan, Mongolia, Singapore, South Korea, Taiwan, Vietnam, has allowed them to fare comparatively well. China was criticised for initially minimising the severity of the outbreak, but its wide-scale response has largely contained the disease since March 2020. As of 29 January 2021, Singapore has the lowest case fatality rate in the world at <0.1%.
The pandemic has had direct side effects, per a report on 28 November, in Japan. According to the report by the country's National Police Agency, suicides had increased to 2,153 in October. Experts also state that the pandemic has worsened mental health issues due to lockdowns and isolation from family members, among other issues.
As of 14 July 2020, there are 83,545 cases confirmed in China— excluding 114 asymptomatic cases, 62 of which were imported, under medical observation; asymptomatic cases have not been reported prior to 31 March 2020—with 4,634 deaths and 78,509 recoveries, meaning there are only 402 cases. Hubei has the most cases, followed by Xinjiang. By March 2020, COVID-19 infections have largely been put under control in China, with minor outbreaks since. It was reported on 25 November, that some 1 million people in the country of China have been vaccinated according to China's state council; the vaccines against COVID-19 come from Sinopharm which makes two and one produced by Sinovac.
The first case of COVID-19 in India was reported on 30 January 2020. India ordered a nationwide lockdown for the entire population starting 24 March 2020, with a phased unlock beginning 1 June 2020. Six cities account for around half of all reported cases in the country—Mumbai, Delhi, Ahmedabad, Chennai, Pune and Kolkata. On 10 June 2020, India's recoveries exceeded active cases for the first time.
On 30 August 2020, India surpassed the US record for the most cases in a single day, with more than 78,000 cases, and set a new record on 16 September 2020, with almost 98,000 cases reported that day. As of 30 August 2020, India's case fatality rate is relatively low at 2.3%, against the global 4.7%.[needs update]
As of September 2020, India had the largest number of confirmed cases in Asia; and the second-highest number of confirmed cases in the world, behind the United States, with the number of total confirmed cases breaching the 100,000 mark on 19 May 2020, 1,000,000 on 16 July 2020, and 5,000,000 confirmed cases on 16 September 2020.
On 19 December 2020, India crossed the total number of 10,000,000 confirmed cases but with a slow pace.
The Indian Ministry of Science initiated a mathematical simulation of the pandemic, the so-called "Indian Supermodel", which correctly predicted the decrease of active cases starting in September 2020. In a paper on an improved simulation model published February 2021 the Supermodel authors estimate the immunity of the Indian population to be close to 60% and claim that India might be the only major economy that has successfully implemented a herd immunity strategy by "letting the reach of the virus increase in a controlled manner, so that the medical infrastructure does not get overwhelmed".
Iran reported its first confirmed cases of SARS-CoV-2 infections on 19 February 2020 in Qom, where, according to the Ministry of Health and Medical Education, two people had died that day. Early measures announced by the government included the cancellation of concerts and other cultural events, sporting events, Friday prayers, and closures of universities, higher education institutions, and schools. Iran allocated 5 trillion rials (equivalent to US$120,000,000) to combat the virus. President Hassan Rouhani said on 26 February 2020 there were no plans to quarantine areas affected by the outbreak, and only individuals would be quarantined. Plans to limit travel between cities were announced in March 2020, although heavy traffic between cities ahead of the Persian New Year Nowruz continued. Shia shrines in Qom remained open to pilgrims until 16 March.
Iran became a centre of the spread of the virus after China during February 2020. More than ten countries had traced their cases back to Iran by 28 February, indicating the outbreak may have been more severe than the 388 cases reported by the Iranian government by that date. The Iranian Parliament was shut down, with 23 of its 290 members reported to have had tested positive for the virus on 3 March 2020. On 15 March 2020, the Iranian government reported a hundred deaths in a single day, the most recorded in the country since the outbreak began. At least twelve sitting or former Iranian politicians and government officials had died from the disease by 17 March 2020. By 23 March 2020, Iran was experiencing fifty new cases every hour and one new death every ten minutes due to coronavirus. According to a WHO official, there may be five times more cases in Iran than what is being reported. It is also suggested that U.S. sanctions on Iran may be affecting the country's financial ability to respond to the viral outbreak.
On 20 April 2020, Iran reopened shopping malls and other shopping areas across the country. After reaching a low in new cases in early May, a new peak was reported on 4 June 2020, raising fear of a second wave. On 18 July 2020, President Rouhani estimated that 25 million Iranians had already become infected, which is considerably higher than the official count. Leaked data suggest that 42,000 people had died with COVID-19 symptoms by 20 July 2020, nearly tripling the 14,405 officially reported by that date.
COVID-19 was confirmed to have spread to South Korea on 20 January 2020 from China. The nation's health agency reported a significant increase in confirmed cases on 20 February, largely attributed to a gathering in Daegu of the Shincheonji Church of Jesus. Shincheonji devotees visiting Daegu from Wuhan were suspected to be the origin of the outbreak. By 22 February[update], among 9,336 followers of the church, 1,261 or about 13 percent reported symptoms. South Korea declared the highest level of alert on 23 February 2020. On 29 February, more than 3,150 confirmed cases were reported. All South Korean military bases were quarantined after tests showed three soldiers had the virus. Airline schedules were also changed.
South Korea introduced what was considered the largest and best-organised programme in the world to screen the population for the virus, isolate any infected people, and trace and quarantine those who contacted them. Screening methods included mandatory self-reporting of symptoms by new international arrivals through mobile application, drive-through testing for the virus with the results available the next day, and increasing testing capability to allow up to 20,000 people to be tested every day. Despite some early criticisms of President Moon Jae-in's response to the crisis, South Korea's programme is considered a success in controlling the outbreak without quarantining entire cities.
On 23 March, it was reported that South Korea had the lowest one-day case total in four weeks. On 29 March it was reported that beginning 1 April all new overseas arrivals will be quarantined for two weeks. Per media reports on 1 April, South Korea has received requests for virus testing assistance from 121 different countries. Persistent local groups of infections in the greater Seoul area continued to be found, which led to Korea's CDC director saying in June that the country had entered the second wave of infections, although a WHO official disagreed with that assessment.
As of 13 March 2020,[update] when the number of new cases became greater than those in China, the World Health Organization (WHO) began to consider Europe the active centre of the pandemic. Cases by country across Europe had doubled over periods of typically 3 to 4 days, with some countries (mostly those at earlier stages of detection) showing doubling every 2 days.
As of 17 March,[update] all countries within Europe had a confirmed case of COVID-19, with Montenegro being the last European country to report at least one case. At least one death has been reported in all European countries, apart from the Vatican City.
As of 18 March,[update] more than 250 million people were in lockdown in Europe.
On 21 August, it was reported the COVID-19 cases were climbing among younger individuals across Europe. On 21 November, it was reported by the Voice of America that Europe is the worst hit area by the COVID-19 virus, with numbers exceeding 15 million cases.
Although it was originally thought the pandemic reached France on 24 January 2020, when the first COVID-19 case in Europe was confirmed in Bordeaux, it was later discovered that a person near Paris had tested positive for the virus on 27 December 2019 after retesting old samples. A key event in the spread of the disease in the country was the annual assembly of the Christian Open Door Church between 17 and 24 February in Mulhouse, which was attended by about 2,500 people, at least half of whom are believed to have contracted the virus.
On 13 March, Prime Minister Édouard Philippe ordered the closure of all non-essential public places, and on 16 March, French President Emmanuel Macron announced mandatory home confinement, a policy which was extended at least until 11 May. As of 14 September[update], France has reported more than 402,000 confirmed cases, 30,000 deaths, and 90,000 recoveries, ranking fourth in number of confirmed cases. In April, there were riots in some Paris suburbs. On 18 May, it was reported that schools in France had to close again after reopening, due to COVID-19 case flare-ups.
On 12 November, it was reported that France had become the worst-hit country by the COVID-19 pandemic, in all of Europe, in the process surpassing Russia. The new total of confirmed cases was more than 1.8 million and counting; additionally it was indicated by the French government that the current national lockdown would remain in place.
The outbreak was confirmed to have spread to Italy on 31 January, when two Chinese tourists tested positive for SARS-CoV-2 in Rome. Cases began to rise sharply, which prompted the Italian government to suspend all flights to and from China and declare a state of emergency. An unassociated cluster of COVID-19 cases was later detected, starting with 16 confirmed cases in Lombardy on 21 February.
On 22 February, the Council of Ministers announced a new decree-law to contain the outbreak, including quarantining more than 50,000 people from eleven different municipalities in northern Italy. Prime Minister Giuseppe Conte said, "In the outbreak areas, entry and exit will not be provided. Suspension of work activities and sports events has already been ordered in those areas."
On 4 March, the Italian government ordered the full closure of all schools and universities nationwide as Italy reached a hundred deaths. All major sporting events were to be held behind closed doors until April, but on 9 March, all sport was suspended completely for at least one month. On 11 March, Prime Minister Conte ordered stoppage of nearly all commercial activity except supermarkets and pharmacies.
On 6 March, the Italian College of Anaesthesia, Analgesia, Resuscitation and Intensive Care (SIAARTI) published medical ethics recommendations regarding triage protocols. On 19 March, Italy overtook China as the country with the most coronavirus-related deaths in the world after reporting 3,405 fatalities from the pandemic. On 22 March, it was reported that Russia had sent nine military planes with medical equipment to Italy. As of 14 September[update], there were 287,753 confirmed cases, 35,610 deaths, and 213,634 recoveries in Italy, with the majority of those cases occurring in the Lombardy region. A CNN report indicated that the combination of Italy's large elderly population and inability to test all who have the virus to date may be contributing to the high fatality rate. On 19 April, it was reported that the country had its lowest deaths at 433 in seven days and some businesses were asking for a loosening of restrictions after six weeks of lockdown. On 13 October 2020, the Italian government again issued restrictive rules to contain a rise in infections.
On 11 November, it was reported that Silvestro Scotti, president of the Italian Federation of General Practitioners indicated that all of Italy should come under restrictions due to the coronavirus. A couple of days prior Filippo Anelli, president of the National Federation of Doctor's Guilds (FNOMCEO) asked for a complete lockdown of the peninsular nation due to the pandemic. On the 10th, a day before, Italy surpassed 1 million confirmed COVID-19 cases. On 23 November, it was reported that the second wave of the virus has caused some hospitals in Italy to stop accepting patients.
The virus was first confirmed to have spread to Spain on 31 January 2020, when a German tourist tested positive for SARS-CoV-2 in La Gomera, Canary Islands. Post-hoc genetic analysis has shown that at least 15 strains of the virus had been imported, and community transmission began by mid-February. By 13 March, cases had been confirmed in all 50 provinces of the country.
A lockdown was imposed on 14 March 2020. On 29 March, it was announced that, beginning the following day, all non-essential workers were ordered to remain at home for the next 14 days. By late March, the Community of Madrid has recorded the most cases and deaths in the country. Medical professionals and those who live in retirement homes have experienced especially high infection rates. On 25 March, the official death toll in Spain surpassed that of mainland China. On 2 April, 950 people died of the virus in a 24-hour period—at the time, the most by any country in a single day. On 17 May, the daily death toll announced by the Spanish government fell below 100 for the first time, and 1 June was the first day without deaths by coronavirus. The state of alarm ended on 21 June. However, the number of cases increased again in July in a number of cities including Barcelona, Zaragoza and Madrid, which led to reimposition of some restrictions but no national lockdown.
Sweden differed from most other European countries in that it mostly remained open. Per the Swedish Constitution, the Public Health Agency of Sweden has autonomy which prevents political interference and the agency's policy favoured forgoing a lockdown. The Swedish strategy focused on measures that could be put in place over a longer period of time, based on the assumption that the virus would start spreading again after a shorter lockdown. The New York Times said that, as of May 2020, the outbreak had been far deadlier there but the economic impact had been reduced as Swedes have continued to go to work, restaurants, and shopping. On 19 May, it was reported that the country had in the week of 12–19 May the highest per capita deaths in Europe, 6.25 deaths per million per day. In the end of June, Sweden no longer had excess mortality.
Devolution in the United Kingdom meant that each of the four countries of the UK had its own different response to COVID-19, and the UK government, on behalf of England, moved quicker to lift restrictions. The UK government started enforcing social distancing and quarantine measures on 18 March 2020 and was criticised for a perceived lack of intensity in its response to concerns faced by the public. On 16 March, Prime Minister Boris Johnson advised against non-essential travel and social contact, suggesting people work from home and avoid venues such as pubs, restaurants, and theatres. On 20 March, the government ordered all leisure establishments to close as soon as possible, and promised to prevent unemployment. On 23 March, Johnson banned gatherings of multiple people and restricting non-essential travel and outdoor activity. Unlike previous measures, these restrictions were enforceable by police through fines and dispersal of gatherings. Most non-essential businesses were ordered to close.
On 24 April, it was reported that a promising vaccine trial had begun in England; the government pledged more than £50 million towards research. A number of temporary critical care hospitals were built. The first operating was the 4,000-bed NHS Nightingale Hospital London, constructed for over nine days. On 4 May, it was announced that it would be placed on standby and remaining patients transferred to other facilities; 51 patients had been treated in the first three weeks.
On 16 April, it was reported that the UK would have first access to the Oxford vaccine, due to a prior contract; should the trial be successful, some 30 million doses in the UK would be available.
On 2 December, the UK became the first Western country to approve the Pfizer vaccine against the COVID-19 virus; 800,000 doses would be immediately available for use. It was reported on 5 December that the United Kingdom would begin vaccination against the virus on 8 December, less than a week after having been approved. On 9 December, MHRA stated that any individual with a significant allergic reaction to a vaccine, such as an anaphylactoid reaction, should not take the Pfizer vaccine for COVID-19 protection.
The first cases in North America were reported in the United States in January 2020. Cases were reported in all North American countries after Saint Kitts and Nevis confirmed a case on 25 March, and in all North American territories after Bonaire confirmed a case on 16 April.
More than 28,800,000 confirmed cases have been reported in the United States since January 2020, resulting in more than 522,000 deaths, the most of any country and the ninth-highest per capita. The U.S. has nearly a quarter of the world's cases and a fifth of all deaths. More Americans have died from COVID-19 than during World War II. COVID-19 became the third leading cause of death in the U.S. in 2020, behind heart disease and cancer. U.S. life expectancy dropped from 78.8 years in 2019 to 77.8 years in the first half of 2020.
The first American case was reported on January 20, and President Donald Trump declared the U.S. outbreak a public health emergency on January 31. Restrictions were placed on flights arriving from China, but the initial U.S. response to the pandemic was otherwise slow, in terms of preparing the healthcare system, stopping other travel, and testing. Meanwhile, Trump remained optimistic on the future of the coronavirus in the United States.
The pandemic was confirmed to have reached South America on 26 February 2020 when Brazil confirmed a case in São Paulo. By 3 April, all countries and territories in South America had recorded at least one case.
On 13 May, it was reported that Latin America and the Caribbean had reported over 400,000 cases of COVID-19 infection with, 23,091 deaths. On 22 May, citing the rapid increase of infections in Brazil, the WHO declared South America the epicentre of the pandemic.
On 20 May, it was reported that Brazil had a record 1,179 deaths in a single day, for a total of almost 18,000 fatalities. With a total number of almost 272,000 cases, Brazil became the country with the third-highest number of cases, following Russia and the United States. On 25 May, Brazil exceeded the number of reported cases in Russia when they reported that 11,687 new cases had been confirmed over the previous 24 hours, bringing the total number to over 374,800, with more than 23,400 deaths. President Jair Bolsonaro has created controversy by referring to the virus as a "little flu" and frequently speaking out against preventive measures such as lockdowns and quarantines. His attitude towards the outbreak has been likened to that of former U.S. President Trump, with Bolsonaro being called the "Trump of the Tropics". Bolsonaro later tested positive for the virus.
In June 2020, the government of Brazil attempted to conceal the actual figures of the COVID-19 active cases and deaths, as it stopped publishing the total number of infections and deaths. On 5 June, Brazil's health ministry took down the official website reflecting the total numbers of infections and deaths. The website was live on 6 June, with only the number of infections of the previous 24 hours. The last official numbers reported about 615,000 infections and over 34,000 deaths. On 15 June, it was reported that the worldwide cases had jumped from seven to eight million in one week, citing Latin America, specifically Brazil as one of the countries where cases are surging, in this case, towards 1 million cases. Brazil briefly paused Phase III trials for the CoronavacCOVID-19 vaccine on 10 November after the suicide of a volunteer before resuming on 11 November.
By early 2021, the death toll had climbed to 231,534. The total number of cases on 7 February exceeded 9.5 million. The only countries with worse outbreaks were India and the United States.
The pandemic was confirmed to have spread to Africa on 14 February 2020, with the first confirmed case announced in Egypt. The first confirmed case in sub-Saharan Africa was announced in Nigeria at the end of February. Within three months, the virus had spread throughout the continent, as Lesotho, the last African sovereign state to have remained free of the virus, reported a case on 13 May. By 26 May, it appeared that most African countries were experiencing community transmission, although testing capacity was limited. Most of the identified imported cases arrived from Europe and the United States rather than from China where the virus originated. It is believed that there is widespread under-reporting in many African countries with less developed healthcare systems.
New strains of the virus were found in December 2020 in South Africa and Nigeria, in addition to the Lineage B.1.1.7 variant reported in the United Kingdom in September.
As a result of the pandemic, many countries and regions imposed quarantines, entry bans, or other restrictions, either for citizens, recent travellers to affected areas, or for all travellers. Together with a decreased willingness to travel, this had a negative economic and social impact on the travel sector. Concerns have been raised over the effectiveness of travel restrictions to contain the spread of COVID-19. A study in Science found that travel restrictions had only modestly affected the initial spread of COVID-19, unless combined with infection prevention and control measures to considerably reduce transmissions. Researchers concluded that "travel restrictions are most useful in the early and late phase of an epidemic" and "restrictions of travel from Wuhan unfortunately came too late".
The European Union rejected the idea of suspending the Schengen free travel zone and introducing border controls with Italy, a decision which has been criticised by some European politicians.
Owing to the effective lockdown of Wuhan and Hubei, several countries evacuated their citizens and diplomatic staff from the area, primarily through chartered flights of the home nation, with Chinese authorities providing clearance. Canada, the United States, Japan, India, Sri Lanka, Australia, France, Argentina, Germany, and Thailand were among the first to plan the evacuation of their citizens. Brazil and New Zealand also evacuated their own nationals and some other people. On 14 March 2020, South Africa repatriated 112 South Africans who tested negative for the virus from Wuhan, while four who showed symptoms were left behind to mitigate risk. Pakistan said it would not evacuate citizens from China.
On 15 February 2020, the U.S. announced it would evacuate Americans aboard the cruise ship Diamond Princess, and on 21 February, Canada evacuated 129 Canadian passengers from the ship. In early March, the Indian government began evacuating its citizens from Iran. On 20 March, the United States began to partially withdraw its troops from Iraq due to the pandemic.
The United Nations response to the pandemic has been led by its Secretary-General and can be divided into formal resolutions at the General Assembly and the Security Council (UNSC), and operations via its specialised agencies.
In June 2020, the Secretary-General launched its 'UN Comprehensive Response to COVID-19'. The United Nations Conference on Trade and Development (UNSC) has been criticised for a slow coordinated response, especially regarding the UN's global ceasefire, which aims to open up humanitarian access to the world's most vulnerable in conflict zones.
The WHO is a leading organisation involved in the global coordination for mitigating the pandemic.
The WHO has spearheaded several initiatives like the COVID-19 Solidarity Response Fund to raise money for the pandemic response, the UN COVID-19 Supply Chain Task Force, and the solidarity trial for investigating potential treatment options for the disease. The WHO's COVAX vaccine-sharing program aims to distribute 2 billion doses of COVID-19 vaccine for free or at a reduced cost by the end of 2021, and has begun distributing them.
In several countries, protests have risen against governmental restrictive responses to the COVID-19 pandemic, such as lockdowns – ironically, some of these protests have been directly linked to a rise in cases.
The outbreak is a major destabilising threat to the global economy. Agathe Demarais of the Economist Intelligence Unit has forecast that markets will remain volatile until a clearer image emerges on potential outcomes. One estimate from an expert at Washington University in St. Louis gave a $300+ billion impact on the world's supply chain that could last up to two years. Global stock markets fell on 24 February due to a significant rise in the number of COVID-19 cases outside China. On 27 February, due to mounting worries about the coronavirus outbreak, U.S. stock indexes posted their sharpest falls since 2008, with the Dow falling 1,191 points (the largest one-day drop since the financial crisis of 2007–08) and all three major indexes ending the week down more than 10 percent. On 28 February, Scope Ratings GmbH affirmed China's sovereign credit rating but maintained a Negative Outlook. Stocks plunged again due to coronavirus fears, the largest fall being on 16 March.
Lloyd's of London has estimated that the global insurance industry will absorb losses of US$204 billion, exceeding the losses from the 2017 Atlantic hurricane season and 11 September attacks, suggesting the COVID-19 pandemic will likely go down in history as the costliest disaster ever in human history.
Tourism is one of the worst affected sectors due to travel bans, closing of public places including travel attractions, and advice of governments against travel. Numerous airlines have cancelled flights due to lower demand, and British regional airline Flybe collapsed. The cruise line industry was hard hit, and several train stations and ferry ports have also been closed. International mail between some countries stopped or was delayed due to reduced transportation between them or suspension of domestic service.
The retail sector has been impacted globally, with reductions in store hours or temporary closures. Visits to retailers in Europe and Latin America declined by 40 percent. North America and Middle East retailers saw a 50–60 percent drop. This also resulted in a 33–43 percent drop in foot traffic to shopping centres in March compared to February. Shopping mall operators around the world imposed additional measures, such as increased sanitation, installation of thermal scanners to check the temperature of shoppers, and cancellation of events.
Hundreds of millions of jobs could be lost globally. More than 40 million Americans lost their jobs and filed unemployment insurance claims. The economic impact and mass unemployment caused by the pandemic has raised fears of a mass eviction crisis, with an analysis by the Aspen Institute indicating between 30 and 40 million Americans are at risk for eviction by the end of 2020. According to a report by Yelp, about 60% of U.S. businesses that have closed since the start of the pandemic will stay shut permanently.
According to a United Nations Economic Commission for Latin America estimate, the pandemic-induced recession could leave 14–22 million more people in extreme poverty in Latin America than would have been in that situation without the pandemic. According to the World Bank, up to 100 million more people globally could fall into extreme poverty due to the shutdowns. The International Labour Organization (ILO) informed that the income generated in the first nine months of 2020 from work across the world dropped by 10.7 per cent, or $3.5 trillion, amidst the coronavirus outbreak.
The outbreak has been blamed for several instances of supply shortages, stemming from globally increased usage of equipment to fight outbreaks, panic buying (which in several places led to shelves being cleared of grocery essentials such as food, toilet paper, and bottled water), and disruption to factory and logistic operations. The spread of panic buying has been found to stem from perceived threat, perceived scarcity, fear of the unknown, coping behaviour and social psychological factors (e.g. social influence and trust). The technology industry, in particular, has warned of delays to shipments of electronic goods. According to the WHO director-general Tedros Adhanom, demand for personal protection equipment has risen a hundredfold, leading to prices up to twenty times the normal price and also delays in the supply of medical items of four to six months. It has also caused a shortage of personal protective equipment worldwide, with the WHO warning that this will endanger health workers.
The impact of the coronavirus outbreak was worldwide. The virus created a shortage of precursors (raw material) used in the manufacturing of fentanyl and methamphetamine. The Yuancheng Group, headquartered in Wuhan, is one of the leading suppliers. Price increases and shortages in these illegal drugs have been noticed on the streets of the UK. U.S. law enforcement also told the New York Post Mexican drug cartels were having difficulty in obtaining precursors.
The pandemic has disrupted global food supplies and threatens to trigger a new food crisis. David Beasley, head of the World Food Programme (WFP), said "we could be facing multiple famines of biblical proportions within a short few months." Senior officials at the United Nations estimated in April 2020 that an additional 130 million people could starve, for a total of 265 million by the end of 2020.
In early February 2020, Organization of the Petroleum Exporting Countries (OPEC) "scrambled" after a steep decline in oil prices due to lower demand from China. On Monday, 20 April, the price of West Texas Intermediate (WTI) went negative and fell to a record low (minus $37.63 a barrel) due to traders' offloading holdings so as not to take delivery and incur storage costs. June prices were down but in the positive range, with a barrel of West Texas trading above $20.
The performing arts and cultural heritage sectors have been profoundly affected by the pandemic, impacting organisations' operations as well as individuals—both employed and independent—globally. Arts and culture sector organisations attempted to uphold their (often publicly funded) mission to provide access to cultural heritage to the community, maintain the safety of their employees and the public, and support artists where possible. By March 2020, across the world and to varying degrees, museums, libraries, performance venues, and other cultural institutions had been indefinitely closed with their exhibitions, events and performances cancelled or postponed. In response there were intensive efforts to provide alternative services through digital platforms.
Holy Week observances in Rome, which occur during the last week of the Christian penitential season of Lent, were cancelled. Many dioceses have recommended older Christians stay home rather than attend Mass on Sundays; services have been made available via radio, online live streaming and television, though some congregations have made provisions for drive-in worship. With the Roman Catholic Diocese of Rome closing its churches and chapels and St. Peter's Square emptied of Christian pilgrims, other religious bodies also cancelled in-person services and limited public gatherings in churches, mosques, synagogues, temples and gurdwaras. Iran's Health Ministry announced the cancellation of Friday prayers in areas affected by the outbreak and shrines were later closed, while Saudi Arabia banned the entry of foreign pilgrims as well as its residents to holy sites in Mecca and Medina. The 2020 Hajj was limited to around 1,000 selected pilgrims, in contrast to the usual number of over 2 million.
The pandemic has caused the most significant disruption to the worldwide sporting calendar since the Second World War. Most major sporting events have been cancelled or postponed, including the 2019–20 UEFA Champions League, 2019–20 Premier League, UEFA Euro 2020, 2019–20 NBA season, and 2019–20 NHL season. The outbreak disrupted plans for the 2020 Summer Olympics in Tokyo, Japan, which were originally scheduled to start at 24 July 2020, and were postponed by the International Olympic Committee to 23 July 2021.
The entertainment industry has also been affected, with many music groups suspending or cancelling concert tours. The Eurovision Song Contest, which was due to be held in Rotterdam, the Netherlands in May, was cancelled; however, the Netherlands was retained as host for 2021. Many large theatres such as those on Broadway also suspended all performances. Some artists have explored ways to continue to produce and share work over the internet as an alternative to traditional live performance, such as live streaming concerts or creating web-based "festivals" for artists to perform, distribute, and publicise their work.
The large number of people working or learning from home via videoconferencing software led to several new terms and trends, including "Zoom fatigue", a decline in demand for formal clothing, and increased fashion focus on masks and clothes for the upper body (the lower body generally not being visible on a videoconference). The term "doomscrolling" became more widely used. Online, numerous COVID-19-themed Internet memes have spread as many turn to humour and distraction amid the uncertainty. A popular Twitter account called "Room Rater" jokingly commented on and assigned numerical scores to the backgrounds of journalists and others appearing in mass media from home.
The pandemic has affected the political systems of multiple countries, causing suspensions of legislative activities, isolations or deaths of multiple politicians, and rescheduling of elections due to fears of spreading the virus. Starting in late May, large-scale protests against police brutality in at least 200 U.S. cities and later worldwide in response to the killing of George Floyd raised concerns of a resurgence of the virus, although research has determined that they were not.
Although they have broad support among epidemiologists, social distancing measures have been politically controversial in many countries. Intellectual opposition to social distancing has come primarily from writers of other fields, although there are a few heterodox epidemiologists.
On 23 March 2020, United Nations Secretary-General António Manuel de Oliveira Guterres issued an appeal for a global ceasefire in response to the pandemic; 172 UN Member States and Observers signed a non-binding statement in support of the appeal in June, and the UN Security Council passed a resolution supporting it in July.
The government of China has been criticised by the United States, the UK Minister for the Cabinet Office Michael Gove, and others for its handling of the pandemic. A number of provincial-level administrators of the Communist Party of China were dismissed over their handling of the quarantine measures in China, a sign of discontent with their response to the outbreak. Some commentators believed this move was intended to protect CCP general secretary Xi Jinping from the controversy. The U.S. intelligence community claims China intentionally under-reported its number of coronavirus cases. The Chinese government maintains it has acted swiftly and transparently. However, journalists and activists who have reported on the pandemic have been detained by authorities, such as Zhang Zhan, who was arrested and tortured for reporting on the pandemic and the detainment of other independent journalists.
In early March, the Italian government criticised the EU's lack of solidarity with coronavirus-affected Italy—Maurizio Massari, Italy's ambassador to the EU, said "only China responded bilaterally", not the EU. On 22 March, after a phone call with Italian Prime Minister Giuseppe Conte, Russian president Vladimir Putin had the Russian army send military medics, disinfection vehicles, and other medical equipment to Italy. President of Lombardy Attilio Fontana and Italian Foreign Minister Luigi Di Maio expressed their gratitude for the aid. Russia also sent a cargo plane with medical aid to the United States. Kremlin spokesman Dmitry Peskov said "when offering assistance to U.S. colleagues, [Putin] assumes that when U.S. manufacturers of medical equipment and materials gain momentum, they will also be able to reciprocate if necessary." In early April, Norway and EU states like Romania and Austria started to offer help by sending medical personnel and disinfectant, and Ursula von der Leyen offered an official apology to the country.
The outbreak prompted calls for the United States to adopt social policies common in other wealthy countries, including universal health care, universal child care, paid sick leave, and higher levels of funding for public health. Political analysts believe it may have contributed to Donald Trump's loss in the 2020 presidential election. Beginning in mid-April 2020, there were protests in several U.S. states against government-imposed business closures and restricted personal movement and association. Simultaneously, protests ensued by essential workers in the form of a general strike. In early October 2020, Donald Trump, his family members, and many other government officials were diagnosed with COVID-19, further disrupting the country's politics.
The planned NATO "Defender 2020" military exercise in Germany, Poland, and the Baltic states, the largest NATO war exercise since the end of the Cold War, was held on a reduced scale. The Campaign for Nuclear Disarmament's general secretary Kate Hudson criticised the exercise, saying "it jeopardises the lives not only of the troops from the U.S. and the many European countries participating but the inhabitants of the countries in which they are operating."
The Iranian government has been heavily affected by the virus, with about two dozen parliament members and fifteen current or former political figures infected. Iran's President Hassan Rouhani wrote a public letter to world leaders asking for help on 14 March 2020, saying they were struggling to fight the outbreak due to a lack of access to international markets from the United States sanctions against Iran. Saudi Arabia, which launched a military intervention in Yemen in March 2015, declared a ceasefire.
Diplomatic relations between Japan and South Korea worsened due to the pandemic. South Korea criticised Japan's "ambiguous and passive quarantine efforts" after Japan announced anyone coming from South Korea would be placed in quarantine for two weeks at government-designated sites. South Korean society was initially polarised on President Moon Jae-in's response to the crisis; many Koreans signed petitions either calling for Moon's impeachment or praising his response.
Some countries have passed emergency legislation in response to the pandemic. Some commentators have expressed concern that it could allow governments to strengthen their grip on power. In the Philippines, lawmakers granted president Rodrigo Duterte temporary emergency powers during the pandemic. In Hungary, the parliament voted to allow the prime minister, Viktor Orbán, to rule by decree indefinitely, suspend parliament as well as elections, and punish those deemed to have spread false information about the virus and the government's handling of the crisis. In some countries, including Egypt, Turkey, and Thailand, opposition activists and government critics have been arrested for allegedly spreading fake news about the COVID-19 pandemic.
In India, journalists criticising the government's response were arrested or issued warnings by police and authorities. Rates of imprisoned or detained journalists increased worldwide, with some being related to the pandemic.
The government of the UK faced criticism for after the now-former Chief of Staff Dominic Cummings was discovered multiple times breaking lockdown.
The COVID-19 pandemic has disrupted agricultural and food systems worldwide. COVID-19 hit at a time when hunger or undernourishment was once again on the rise in the world, with an estimated 690 million people already going hungry in 2019. Based on the latest UN estimates, the economic recession triggered by the pandemic may lead to another 83 million people, and possibly as many as 132 million, going hungry in 2020. This is mainly due to a lack of access to food – linked to falling incomes, lost remittances and, in some cases, a rise in food prices. In countries that already suffer from high levels of acute food insecurity, it is no longer an issue of access to food alone, but increasingly also one of food production.
The pandemic, alongside lockdowns and travel restrictions, has prevented movement of aid and greatly impacted food production. As a result, several famines are forecast, which the UN called a crisis "of biblical proportions," or "hunger pandemic." It is estimated that without intervention 30 million people may die of hunger, with Oxfam reporting that "12,000 people per day could die from COVID-19 linked hunger" by the end of 2020. This pandemic, in conjunction with the 2019–2021 locust infestations and several ongoing armed conflicts, is predicted to form the worst series of famines since the Great Chinese Famine, affecting between 10 and 20 percent of the global population in some way. 55 countries are reported to be at risk, with three dozen succumbing to crisis-level famines or above in the worst-case scenario. 265 million people are forecast to be in famine conditions, an increase of 125 million due to the coronavirus pandemic.
The pandemic has severely impacted educational systems globally. Most governments have temporarily closed educational institutions, with many switching to online education. As of 30 September 2020, approximately 1.077 billion learners are currently affected due to school closures in response to the pandemic. According to UNICEF monitoring, 53 countries are currently implementing nationwide closures and 27 are implementing local closures, impacting about 61.6 percent of the world's student population. 72 countries' schools are currently open. School closures impact not only students, teachers, and families but have far-reaching economic and societal consequences. School closures in response to the pandemic have shed light on various social and economic issues, including student debt, digital learning, food insecurity, and homelessness, as well as access to childcare, health care, housing, internet, and disability services. The impact has been more severe for disadvantaged children and their families.
The pandemic has had many impacts on global health beyond those caused by the COVID-19 disease itself. It has led to a reduction in hospital visits for other reasons. There have been 38 per cent fewer hospital visits for heart attack symptoms in the United States and 40 per cent fewer in Spain. The head of cardiology at the University of Arizona said, "My worry is some of these people are dying at home because they're too scared to go to the hospital." There is also concern that people with strokes and appendicitis are not seeking timely treatment. Shortages of medical supplies have impacted people with various conditions.
In several countries there has been a marked reduction of spread of sexually transmitted infections, including HIV/AIDS, attributable to COVID-19 quarantines, social distancing measures, and recommendations to not engage in casual sex. Similarly, in some places, rates of transmission of influenza and other respiratory viruses significantly decreased during the pandemic.
The worldwide disruption caused by the pandemic has resulted in numerous effects on the environment and climate. The global reduction in modern human activity such as the considerable decline in planned travel was coined anthropause and has caused a large drop in air pollution and water pollution in many regions. In China, lockdowns and other measures resulted in a 25 percent reduction in carbon emissions and 50 percent reduction in nitrogen oxides emissions, which one Earth systems scientist estimated may have saved at least 77,000 lives over two months. Other positive effects on the environment include governance-system-controlled investments towards a sustainable energy transition and other goals related to environmental protection such as the European Union's seven-year €1 trillion budget proposal and €750 billion recovery plan "Next Generation EU" which seeks to reserve 25% of EU spending for climate-friendly expenditure.
However, the pandemic has also provided cover for illegal activities such as deforestation of the Amazon rainforest and poaching in Africa, hindered environmental diplomacy efforts, and created economic fallout that some predict will slow investment in green energy technologies.
Heightened prejudice, xenophobia, and racism have been documented around the world toward people of Chinese and East and Southeast Asian descent. Reports from February 2020 (when most confirmed cases were confined to China) documented racist sentiments expressed in groups worldwide about Chinese people 'deserving' the virus. Chinese people and other Asian peoples in the United Kingdom and United States have reported increasing levels of racist abuse and assaults. Former U.S. President Donald Trump was criticised for referring to the coronavirus as the "Chinese Virus" and "Kung Flu", which has been condemned as racist and xenophobic.
Following the progression of the outbreak to new hotspot countries, people from Italy (the first country in Europe to experience a serious outbreak of COVID-19) were also subjected to suspicion and xenophobia, as were people from hotspots in other countries. Discrimination against Muslims in India escalated after public health authorities identified an Islamic missionary (Tablighi Jamaat) group's gathering in New Delhi in early March 2020 as a source of spread. Paris has seen riots break out over police treatment of marginalised ethnic groups during the coronavirus lockdown. Racism and xenophobia towards South Asian groups increased in the Arab states of the Persian Gulf. In China, some people of African descent were evicted from their homes and told to leave China within 24 hours, due to disinformation that they and other foreigners were spreading the virus. This policy was criticised by some foreign governments, diplomatic corps, and the Chinese ambassador to Zimbabwe.
Ongoing COVID-19 research is indexed and searchable in the NIH COVID-19 Portfolio. Some newspaper agencies removed their online paywalls for some or all of their coronavirus-related articles and posts, while scientific publishers made scientific papers related to the outbreak available with open access. Some scientists chose to share their results quickly on preprint servers such as bioRxiv.
Maps have played a key role in disseminating information concerning the spatial distribution of the disease, especially with the development of dashboards to present data in near real-time. Methods of data visualisation have drawn some criticism, however, in the over-simplification of geographical patterns indicated by choropleth maps that adopt national, rather than local, map scales.
The COVID-19 pandemic has resulted in misinformation and conspiracy theories about the scale of the pandemic and the origin, prevention, diagnosis, and treatment of the disease. False information, including intentional disinformation, has been spread through social media, text messaging, and mass media. Journalists have been arrested for allegedly spreading fake news about the pandemic. False information has also been propagated by celebrities, politicians, and other prominent public figures. A Cornell University study found that US President Donald Trump was "likely the largest driver" of the COVID-19 misinformation infodemic in English-language media. The spread of COVID-19 misinformation by governments has also been significant.
Commercial scams have claimed to offer at-home tests, supposed preventives, and "miracle" cures. Several religious groups have claimed their faith will protect them from the virus. Without evidence, some people have claimed the virus is a bioweapon accidentally or purposefully leaked from a laboratory, a population control scheme, the result of a spy operation, or the side effect of 5G upgrades to cellular networks.
