Cryptosporidium is a parasitic protozoan found in water sources and spread through the fecal-oral route. Cryptosporidiosis is characterized by gastroenteritis and is increasingly associated with recreational water sources. On December 3, 2010, Niagara Region Public Health was informed of a laboratory-confirmed case of Cryptosporidium. Over the subsequent two weeks, a total of three additional laboratory-confirmed cases were reported. All cases had visited the same water park in Niagara Region, Canada, over November 14-16, 2010. A total of 12 cases associated with the outbreak ranged in age from 1 to 66 years. This article describes the outbreak, environmental investigation, and control measures. The environmental investigation revealed that the ultraviolet disinfection system was offline on November 14, 2010, which may have allowed for the transmission of Cryptosporidium to bathers. Further research into the detection of Cryptosporidium outbreaks and regulations and guidelines for water park operators may help to decrease future outbreaks.
隐孢子虫是一种寄生原生动物，存在于水源中，并通过粪口途径传播。隐孢子虫病以肠胃炎为特征，且越来越多地与娱乐用水源相关。2010年12月3日，尼亚加拉地区公共卫生部门接到通知，有一例经实验室确诊的隐孢子虫病病例。在随后的两周内，又报告了另外三例经实验室确诊的病例。所有病例均在2010年11月14日至16日期间去过加拿大尼亚加拉地区的同一个水上公园。此次疫情共涉及12例病例，年龄从1岁至66岁不等。本文描述了此次疫情、环境调查及控制措施。环境调查显示，紫外线消毒系统于2010年11月14日停止运行，这可能导致隐孢子虫传播给游泳者。对隐孢子虫病疫情检测以及水上公园运营者的法规和指南进行进一步研究，可能有助于减少未来的疫情发生。
