To determine the relationship between consumption of E. coli contaminated well-water and gastrointestinal illness in rural families.
One hundred and eighty-one families with well-water as a drinking source participated in a one-year follow-up study. Water was tested for E. coli bacteria and health outcomes were monitored for house-hold members.
E. coli in well-water was significantly associated with gastrointestinal illness in family members, however the relationship was modified by the distance from the septic tank to the well. E. coli had an odds ratio of 2.16 [95% CI 1.04, 4.42] if the septic tank was greater than 20 metres from the well and 0.46 [95% CI 0.07, 2.95] if the septic tank was within 20 metres.
Consumption of contaminated well-water is associated with gastrointestinal illness. E. coli can be a useful marker for detecting wells that pose a potential public health problem in rural areas.
确定农村家庭饮用受大肠杆菌污染的井水与胃肠道疾病之间的关系。
181个以井水为饮用水源的家庭参与了一项为期一年的随访研究。对井水进行大肠杆菌检测，并对家庭成员的健康状况进行监测。
井水中的大肠杆菌与家庭成员的胃肠道疾病显著相关，但这种关系会因化粪池与水井的距离而改变。如果化粪池距离水井超过20米，大肠杆菌的比值比为2.16 [95%置信区间1.04, 4.42]；如果化粪池距离水井在20米以内，则为0.46 [95%置信区间0.07, 2.95]。
饮用受污染的井水与胃肠道疾病有关。大肠杆菌可作为检测农村地区存在潜在公共卫生问题的水井的有用标志物。
