A large outbreak of Campylobacter jujuni gastroenteritis attributed to contamination of an unchlorinated municipal water system was investigated. Unlike most previous summer outbreaks, this one began in early spring and was attributed to meltwater entering one or more municipal wells. 241 suspected cases were documented, but retrospective information from local health care workers suggested a much larger outbreak. 45 laboratory-confirmed cases participated in a case-control study which showed a significant association between infection and amount of town water consumed. Stool specimens from 29 patients were studied with detailed serotyping by the method of Lior, with eight known serotypes and one previously unknown one identified. It is concluded that intensive surveillance of water quality during periods of spring runoff is essential, and that timely reporting of disease outbreak patterns in emergency department settings is necessary to protect the public's health.
对一起因未氯化的市政供水系统污染导致的空肠弯曲菌肠胃炎大规模暴发进行了调查。与以往大多数夏季暴发不同，此次暴发始于早春，原因是融水进入了一口或多口市政水井。记录了241例疑似病例，但当地医护人员的回顾性信息表明暴发规模要大得多。45例实验室确诊病例参与了一项病例对照研究，该研究表明感染与城镇用水量之间存在显著关联。采用Lior方法对29例患者的粪便标本进行了详细的血清分型研究，确定了8种已知血清型和1种以前未知的血清型。得出的结论是，在春季径流期间加强水质监测至关重要，在急诊科及时报告疾病暴发模式对于保护公众健康是必要的。
