Ticks can transmit various pathogens. The two most important diseases are:
The most widespread tick species in Switzerland is the wood tick. It prefers deciduous woods with abundant undergrowth, the edge of the forest and forest paths, and waits on low growing plants until a warm-blooded host (person or animal) brushes against the plant. Ticks do not fall from trees.
All areas where ticks occur are considered risk areas for Lyme borreliosis.
The risk areas for ESME include the entire or parts of the cantons ZH, TG, SH, SG, GR, AG, LU, BE, SO, BL, NW, OW, UR, ZG, FR, VD, VS. To date, no areas with ESME-infected ticks have been above an altitude of around 1000 m above sea level.
You will find the latest information on the Federal Office of Public Health’s website about the areas where vaccination is recommended.
There is no vaccination available against Lyme borreliosis. This disease is more common than ESME and can usually be treated with antibiotics.
There is a vaccination against ESME, which the Federal Office of Public Health recommends for people who live or spend time in risk areas. Costs for vaccination in risk areas are covered by compulsory health insurance. The employer pays the cost of vaccination for people who are advised to get vaccinated for professional reasons (forest workers, foresters, farmers).
Infection or toxic reactions caused by insect bites or stings, such as a tick bite, are considered an accident.
