| Russian spring-summer encephalitis virus | An arbovirus of the genus Flavivirus that occurs in Central Europe and the USSR in two subtypes, causing two forms of encephalitis in humans: tick-borne encephalitis (Central European subtype) and tick-borne encephalitis (Eastern subtype); the vectors are ticks of the genus Ixodes.

Synonym: biundulant meningoencephalitis, Central European tick-borne fever, diphasic milk fever, Russian spring-summer encephalitis (Western subtype). 2. (Eastern subtype) tick-borne encephalitis, a severe form of encephalitis caused by a flavivirus, a virus belonging to the Flaviviridae family, and transmitted by ticks (Ixodes pertulcatus and I. Ricinus). Synonym: Russian tick-borne encephalitis. (05 Mar 2000) |
