CDC Warns of Waterborne Illness Risks at Splash Pads Linked to Over 10,000 Cases

A 25-year study reveals Cryptosporidium as the leading cause of outbreaks, prompting calls for stricter safety measures and public education.

The CDC identified 60 waterborne disease outbreaks at splash pads between 1997 and 2022, resulting in 10,611 illnesses, 152 hospitalizations, and 99 emergency visits, with no reported fatalities.
Cryptosporidium, a chlorine-resistant parasite, caused 67% of outbreaks, accounting for 91% of cases and 81% of hospitalizations, primarily affecting young children.
Splash pads face unique challenges in maintaining adequate chlorine levels due to the aerosolization of water, which reduces disinfectant concentration.
The CDC recommends enhanced safety practices, including public education, improved facility management, and the adoption of secondary disinfection methods like UV or ozone treatment.
Parents are urged to prevent sick children from using splash pads, ensure frequent bathroom breaks, and avoid behaviors like sitting on water jets to reduce contamination risks.
