The Czech Republic is grappling with an unprecedented surge in Legionnaires’ disease cases, with infections more than doubling compared to the same period last year. Just a quarter into the year, over 200 cases have been reported, putting the country on track to surpass last year’s record of 620 cases.
The disease, which can lead to pneumonia and presents initially with flu-like symptoms including joint pain, headaches, fever, and cough, has proven particularly dangerous for seniors and immunocompromised individuals. Last year alone, at least fifty deaths were attributed to the infection.
Epidemiologists point to several factors behind this sharp increase, including poorly maintained water pipes, air conditioning systems, and a concerning trend of households reducing their water heating temperatures to save on energy costs. The bacteria thrives in water temperatures between 30-40°C, while experts recommend maintaining hot water temperatures at a minimum of 50°C.
The Czech Republic isn’t alone in this battle. Countries across continents, including Australia, the United States, and Spain, have reported increasing cases. Sources of infection extend beyond household plumbing to include air conditioning units, outdoor cooling mist systems, and industrial cooling towers.
