一系列胃肠道疾病，包括一例溶血性尿毒症综合征和一例培养证实的大肠杆菌O 157：H7感染，发生在拖车公园的游泳池派对之后。我们采访了一群派对参与者和公园居民。原发病例定义为7月5日至7月20日期间家庭内首次发生胃肠道疾病，其中E.大肠杆菌O 157（如测定）升高。在51名参加派对的人和拖车公园的居民中，18人患上了胃肠道疾病，其中10人符合原发病例的定义。在游泳池中游泳显著增加了原发性疾病的风险（相对风险= 6.3; 959%置信区间= 1.8-18.9）。在控制了合并暴露后，没有其他暴露与原发疾病显著相关。在7月4日至10日期间，涉及的游泳池几乎没有添加氯。这次爆发提供了新的证据，证明了适当的游泳池维护在控制传播方面的重要性。coli O157：H7。
A cluster of gastrointestinal illnesses, including one case of hemolytic-uremic syndrome and one culture-confirmed Escherichia coli O157:H7 infection, followed a trailer park pool party. We interviewed a cohort of party attendees and park residents. A primary case was defined as the first gastrointestinal illness within a household between 5 July and 20 July in which the titer of IgG antibody to E. coli O157 (if determined) was elevated. Of 51 party attendees and trailer park residents, 18 developed a gastrointestinal illness, including 10 who met the definition of a primary case. Swimming in the pool significantly increased the risk of primary illness (relative risk = 6.3; 959% confidence interval = 1.8-18.9). No other exposure was significantly associated with primary illness, after pool exposure was controlled for. The implicated pool had little to no chlorine added during the period of 4-10 July. This outbreak provides new evidence of the importance of proper pool maintenance in controlling the spread off. coli O157:H7.
