Fatal Tick-Borne Encephalitis in Unvaccinated Traveler from the United States to Switzerland, 2022.

ABSTRACT: We report an unvaccinated traveler from the United States who contracted fulminant fatal tick-borne encephalitis while visiting Switzerland. Climate changes and international travel are intensifying tick exposure for unvaccinated persons. The increasing incidence of tick-borne encephalitis across Europe underscores the importance of tick bite prevention and vaccination against tick-borne encephalitis virus.
