Objective: An outbreak of skin rash illness was reported from people who had been to a water park located in Yeongcheon-si. Epidemiologic investigation was performed to elucidate the cause of this outbreak and to prevent a recurrence.
Methods: Medical records of clinics and hospitals in Yeongcheon-si were reviewed to find cases of skin rash illness. The manager of the water park was interviewed, and the collected water samples were analyzed and tested for bacterial culture.
Results: Seventy-one cases, consisted of 42 men (59.2%) and 29 women (40.8%), were experienced skin rash illness. Most of the cases (98.6%) were children under 20 years and all cases went to the water park. A swimming pool for adults used underground and lake water, and residual chlorine was not detected. The water samples were positive for various bacteria, including Aeromonas sobria and Pseudomonas putida.
Conclusion: This outbreak was linked to the contaminated water of swimming pools. The water park was reopened after appropriate chlorine disinfection, and another outbreak was not reported until late 2014. Chlorine disinfection of water in swimming pools should be conducted, and enhanced chlorine monitoring is needed.
