In August 1988 an increase was noted in the number of cases of cryptosporidiosis identified by the microbiology laboratory at Doncaster Royal Infirmary. By 31 October, 67 cases had been reported. Preliminary investigations implicated the use of one of two swimming pools at a local sports centre and oocysts were identified in the pool water. Inspection of the pool revealed significant plumbing defects which had allowed ingress of sewage from the main sewer into the circulating pool water. Epidemiological investigation confirmed an association between head immersion and illness. The pools were closed when oocysts were identified in the water and extensive cleaning and repair work was undertaken. The pool water was retested for cryptosporidial oocysts and found to be negative before the pool reopened.
1988年8月，唐卡斯特皇家医院微生物实验室鉴定出的隐孢子虫病病例数量有所增加。到10月31日，已报告67例病例。初步调查表明，当地一个体育中心的两个游泳池中的一个的使用可能与此有关，并且在池水中发现了卵囊。对游泳池的检查发现存在重大的管道缺陷，使得污水从主下水道流入循环池水中。流行病学调查证实头部浸入与疾病之间存在关联。当在水中发现卵囊时，游泳池被关闭，并进行了广泛的清洁和维修工作。在游泳池重新开放之前，对池水重新进行了隐孢子虫卵囊检测，结果为阴性。
