Extremely High Tick Activity in the Czech Republic: Meteorologists Warn of High Risk of Infection

The tick season in the Czech Republic has already started early this year. Experts are therefore warning of a growing risk of Lyme disease and other illnesses – particularly in urban green spaces.

The Czech Hydrometeorological Institute Český hydrometeorologický ústav (ČHMÚ) has warned of exceptionally high tick activity over the long weekend. According to a report by news channel ČT24, the highest warning level five even applies to South Moravia. In large parts of the country, the risk also remains high at level four.

According to meteorologists, warm temperatures combined with high humidity are creating ideal conditions for the parasites. South Moravia is particularly affected, as the region is expected to remain largely unaffected by the current cold front with thunderstorms. However, tick activity also remains high in regions with rainfall, as experts say damp conditions further support the spread of the parasites.

Particularly concerning: experts from the Státní zdravotní ústav (National Institute of Public Health) are warning people not to underestimate the risk of infection in cities. Many people neglect protective measures, especially during short walks in parks or while walking dogs.

While statistically around every tenth tick in forests carries Lyme disease pathogens, experts say the proportion in urban green spaces can be as high as every third tick.

According to the National Reference Laboratories, nearly every second tick now carries at least one pathogen. In addition to Lyme disease, which is widespread in the Czech Republic, illnesses such as anaplasmosis and tularaemia are also becoming increasingly common.

Experts therefore advise people to use repellents even during short stays outdoors and to check their bodies thoroughly after returning home. Ticks can often move around on the body for many hours before finding a suitable place to feed.

The current situation is monitored by experts throughout the year. The ČHMÚ regularly publishes current risk forecasts online and via warning apps such as “Klíšťapka” (Android). Further information about tick activity in the Czech Republic can be found at www.kliste.cz.
