I've been bitten by a tick. What should I do?
In that case immediately go the Red Cross! Do not remove the tick yourself! If there appears a growing reddening around the spot where you have been bitten (mostly a few hours after the incident) you may be infected with borreliosis / Lyme disease. This is a serious disease that has to be treated by a doctor as soon as possible! Borreliosis is easy to treat in early stage. Consider a FSME vaccination before the festival.
