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.
1987年6月,在参加游泳课程的儿童中爆发了一种疾病,调查显示,在室外浅水池游泳的26名儿童比未在浅水池游泳的儿童患病几率更高(比值比12.1,95%置信区间 = 2.9,74.2)。在疾病发作前,泳池氯化系统运行不当,氯含量处于或非常接近零。本报告强调操作人员和检查人员需要特别注意浅水池的消毒。
