Tick-borne encephalitis (TBE) trends in epidemiology and current and future management.
Tick-borne encephalitis (TBE) is considered an international health issue, as the number of risk areas and reported cases across Europe, Russia, and parts of Asia continues to increase. The incidence of TBE has fluctuated considerably from year to year in many countries, but in the past decade the number of TBE cases has significantly increased in the Baltic states, the Czech Republic, and Germany, in addition to occurring in countries previously considered to be free from TBE, such as Denmark (specifically the main island of Zealand), France, and Italy. A number of factors have been suggested to explain the increase in incidence, including climate change, and increased travel and outdoor pursuits, placing people in increased contact with infected ticks. There is no causal treatment available once infected, but TBE can be effectively prevented by vaccination, for which several vaccines are widely available. Three vaccination schedules are available for immunization against TBE, and the recommendations for TBE vaccination vary considerably across the countries in which TBE foci are found. However, plans are in place to raise awareness of TBE and to standardize the vaccination programme across Europe, with the aim of reducing the number of future cases of TBE.
