Tick-borne diseases

Ticks are abundant in woodlands all across Europe from early spring to late autumn. They live by sucking blood from animals and occasionally bite humans.

Ticks themselves do not cause disease but if a tick is infected with a virus or bacterium, then that pathogen can be transmitted through the tick’s bite and cause disease in humans.

Tick-borne encephalitis (TBE) is a common tick-borne disease in Europe (along with Lyme borreliosis).

Factsheet about Borreliosis

Borreliosis, also known as Lyme disease, is caused by the bacterium Borrelia burgdorferi and is transmitted to humans by the bite of infected ticks. If left untreated, infection can spread to joints, the heart, and the nervous system. Most cases of Borreliosis can be treated successfully with a few weeks of antibiotics. No vaccine against Borreliosis is currently available.
