An outbreak of an enterovirus-like illness at a community wading pool: implications for public health inspection...

In June 1987, following an outbreak of an illness among children participating in a swim class, investigation revealed that 26 children who had swum in the outdoor wading pool were more likely to be ill than those who had not (OR 12.1, 95% CI = 2.9, 74.2). The pool chlorination system was operating improperly prior to onset of illness and chlorine levels were at or very near zero. This report emphasizes the need for operators and inspectors to give special attention to disinfection of wading pools.
