Il virus Absettarov (ABSV) è un ceppo di virus dell'encefalite da zecche (TBEV) (sottotipo dell'Estremo Oriente), un arbovirus della famiglia Flaviviridae, genere Flavivirus, ed appartiene al IV gruppo dei virus a ((+) ssRNA).

Fu isolato nel 1951 a Leningrado dal sangue di un bambino di 3 anni con febbre bifasica e segni di meningite. È stato trovato in Svezia, Finlandia, Polonia, nell'ex Cecoslovacchia, Ungheria, Austria, Bulgaria e parti occidentali dell'ex Unione Sovietica. Era considerata una specie solo fino al 2000.

Oggi è noto come il virus dell'encefalite trasmessa da zecche (TBEV) è suddiviso in tre sottotipi: sottotipi europei (TBEV-Eu), siberiani (TBEV-Sib) ed estremo-orientali (TBEV-FE). Questi ceppi sono stati isolati dalle zecche Ixodes persulcatus, dallo scoiattolo macinato a coda lunga (Spermophilus undulatus) e dal sangue umano nei focolai naturali della Siberia occidentale e orientale, in Russia.

È stata segnalata la trasmissione del virus dell'encefalite da zecche (TBEV) nel luglio 2008 attraverso latte di capra non pastorizzato a 6 esseri umani e 4 maiali domestici in un pascolo alpino a 1.500 m sul livello del mare in Austria.

Ricerche mostrano come la 4-iodoantipirina (derivato del fenazone) abbia effetto terapeutico e profilattico nell'encefalite da zecche sperimentale in topi da laboratorio.
