A vaccine is available. The risk to travelers who do not visit or work in forested areas and who avoid unpasteurized dairy products is apparently low. Tickborne Encephalitis occurs chiefly in Central and Western Europe including the countries from the Mediterranean to Scandinavia. It is of particular importance in Austria, Germany, and Switzerland. Tickborne Encephalitis is found less frequently in Finland and Sweden and is rare in Denmark and France.
Transmission occurs in the summer months.
Travelers are at risk if their plans include hiking, camping, or working in or around forested regions. The chance that a traveller to Western Europe will develop Tickborne Encephalitis is probably very small. A vaccine produced by Immuno, Vienna, Austria is not available in the United States. It can be obtained in Europe. Travelers who remain unimmunized should protect themselves from ticks and check for ticks daily.
