1992年1月至6月，俄勒冈州杰克逊县爆发了大规模隐孢子虫病。流行病学调查显示，俄勒冈州塔伦特小社区43例隐孢子虫病与饮用水系统有关。该市一家滤水厂的机械和操作缺陷，以及由于低流量导致的异常糟糕的原水供应条件，可能是疫情爆发的原因。过滤厂缺陷的纠正导致净化水水质大幅改善，这一改善与人才相关疫情的结束相吻合。包括19个参考文献、图表。

From January to June 1992, a large outbreak of cryptosporidiosis occurred in Jackson County, Oregon. Epidemiologic investigations associated 43 cases of cryptosporidiosis with the drinking water system in the small community of Talent, Oregon. Mechanical and operational deficiencies at one of the city's water filtration plants along with unusually poor raw-water supply conditions because of low stream flows were possible cocauses of the outbreak. Correction of the deficiencies in the filter plant resulted in substantial improvement in treated-water quality, and this improvement coincided with the end of the Talent-related outbreak.
