Four hundred fifteen fever cases occurred in village Katkalamba, in Nanded district, Maharashtra during November-December, 1995. Explosive nature of the outbreak, non involvement of infants, significantly higher incidence rate in the age group 1-14 years and clustering of almost all cases in the users of a particular well indicated it to be a water borne outbreak. Laboratory investigations in selected cases confirmed it to be an outbreak of enteric fever. Chemical and microbiological examination of water samples from the suspected wells gave evidence of faecal contamination of water. Circumstances under which the contamination occurred and the outbreak spread are discussed.
1995年11月至12月期间，在马哈拉施特拉邦南德县的卡特卡兰巴村发生了415例发热病例。此次疫情具有爆发性，婴儿未受感染，1至14岁年龄组的发病率显著更高，且几乎所有病例都集中在使用某一口特定水井的人群中，这表明这是一次水源性疫情爆发。对部分病例的实验室调查证实这是一次伤寒热疫情爆发。对疑似水井的水样进行化学和微生物检测发现了水被粪便污染的证据。文中讨论了污染发生及疫情传播的情况。
