Content
Subtypes
Tick-borne encephalitis viruses are divided into three subtypes [2] :
- Far Eastern (the main carrier is the tick Ixodes persulcatus );
- Siberian (the main carrier is the tick Ixodes persulcatus );
- European (the main carrier is the tick Ixodes ricinus ).
The reference strain of tick-borne encephalitis virus is the Sofjin strain [3] .
Evolution
Tick-borne encephalitis virus evolution was studied using bioinformatics methods. It is assumed that the existing subtypes of the virus were divided in the range from 3300 [4] to 2750 [5] years ago, and the separation of the Siberian and Far Eastern subtypes occurred about 2250 years ago [5] .
Distribution
Tick-borne encephalitis virus is thought to have been transmitted to Japan at least three times in the sixteenth and eighteenth centuries [6] . Japanese encephalitis virus is not carried by ticks, but by mosquitoes .
Virus strains circulating in Latvia originate from both Russia and Western Europe [7] , while Estonian strains are primarily of Russian origin [8] , and Lithuanian strains are of Western European origin [9] .
