Tick-borne encephalitis in Switzerland and Liechtenstein

19 Apr 2024

Public health authorities report an increase in cases of tickborne encephalitis in Switzerland and neighbouring Liechtenstein. There were 27 cases in the first three months of 2024, compared to 11 cases in the same period of 2023.

Tick-borne encephalitis (TBE) is an infection spread mainly through tick bites. Infection can also occur through consumption of unpasteurised dairy products. TBE can cause a flu-like illness or lead to more severe symptoms such as meningitis or brain inflammation.

Advice for Travellers

If you are planning to spend long periods of time outdoors in forests or rural areas of countries where TBE infection is common, you should be aware of how to avoid tick bites.

The most effective way to prevent infection is by having the TBE vaccine, particularly if you are planning to do outdoor activities such as walking, hiking, camping, cycling, fishing orienteering or running in rural or forested areas.

When travelling in high risk areas, you should inspect your whole body daily for ticks, particularly after outdoor activities. Ticks should be removed as early as possible. Avoid consuming unpasteurised dairy products.
