Splash pads linked to over 10,000 illnesses in 25 years

December 5, 2024

Study design: This retrospective study analyzed data from CDC's Waterborne Disease and Outbreak Surveillance System (WBDOSS) and the National Outbreak Reporting System (NORS) from 1997 to 2022 and focused on waterborne disease outbreaks associated with splash pads.

Results: Sixty outbreaks were identified across 23 states and Puerto Rico, resulting in 10,611 cases, 152 hospitalizations, and 99 emergency department visits. Cryptosporidium was the most common pathogen, responsible for 91% of cases and 81% of hospitalizations. Norovirus was also implicated in some outbreaks, particularly those leading to emergency department visits.

Impact on clinical practice: Awareness of the potential for waterborne diseases from splash pads is important, especially when treating pediatric patients with GI symptoms. Encouraging preventive measures, such as avoiding splash pads when ill and maintaining proper hygiene, can help mitigate risk of outbreaks. Recognizing chlorine-resistant pathogens like Cryptosporidium is also key for timely diagnosis and effective management.
