Health officials warn of Lyme disease risk from ticks in Prague

About 27 percent of ticks collected in Prague parks and green areas in 2025 were infected with Lyme disease, slightly more than a year earlier, according to the city’s public health authority. The highest share of infected ticks was found in Hostivař Forest Park and the Satalice game reserve, while the lowest was recorded in Klánovice Forest. Health officials say the parasites commonly transmit Lyme disease and tick-borne encephalitis, though only the latter has a vaccine. Authorities advise using repellents and checking the body after time outdoors. Ticks are increasingly active in urban environments due to favourable microclimates and abundant animal hosts.
