West-Nile-Fever (WNV)

The West Nile virus is primarily found in wild birds, though it can also be transmitted to humans (and horses) by mosquitoes. Protection from mosquito bites is the main preventive recommendation. In Switzerland, the West Nile virus was first detected in native mosquitoes in August 2022.
