A large outbreak of hepatitis E occurred in 2005 in Hyderabad, Andhra Pradesh, India. A total of 1611 cases were reported between 1 March and 31 December 2005 (attack rate 40/100,000). The epidemic curve suggested a continuing common source outbreak. Cases were centred around open sewage drains that crossed the old city. The attack rate was significantly higher in neighbourhood blocks supplied by water supply lines that crossed open drains (203/100,000) than in blocks supplied by non-crossing water pipes with a linear trend (38/100 000, P<0.00001). Crossing water pipelines were repaired and the attack rates declined.
2005年,印度安得拉邦海得拉巴市发生了大规模戊型肝炎疫情。2005年3月1日至12月31日期间共报告了1611例病例(发病率为40/10万)。疫情曲线表明这是一次持续的共同来源疫情。病例集中在穿过老城区的露天污水排放管道周围。由穿过露天排水管道的供水管道供水的社区街区的发病率(203/10万)显著高于由不穿过排水管道的水管供水的街区(38/10万,P<0.00001),呈线性趋势。穿过排水管道的供水管道得到了修复,发病率也随之下降。
