Answer

A closely related virus transmitted by the bite of the European sheep tick Ixodes ricinus has been reported in West Germany. Of the other tick-borne viral diseases, the most notable is tick-borne encephalitis, which occurs in Scandinavia, central and eastern Europe, and Russia. A different RNA virus belonging to the Flaviviridae family causes this tick-borne encephalitis and is transmitted by the ticks Ixodes persulcatus and Ixodes ricinus. Effective vaccines are available in Europe and Canada, but not the United States.
