Tick-Borne Diseases on the Rise in the Czech Republic

The number of cases of tick-borne diseases has seen a significant increase in the Czech Republic, with 1,313 cases of Lyme disease detected in the first half of the year, a six percent increase from the previous year, according to data from the National Institute of Public Health. The number of tick-borne encephalitis cases has also remained high, with only one fewer patient than last year, making it a concerning trend. Experts attribute the rise in cases to climate warming, which allows ticks to live at higher altitudes and survive for a greater part of the year. Both illnesses can result in meningitis and require prompt treatment, with Lyme disease caused by a bacterium and treated with antibiotics, while tick-borne encephalitis is caused by a virus.
