An outbreak investigation was initiated following an unusual occurrence of hepatitis A reported among people residing in the coastal belt of Vadi to Vedikunnu area, Kollam district, Kerala, southern India. The time frame of disease occurrence, pattern of its distribution, and the incubation period of hepatitis A infection indicated the probability of occurrence of the outbreak as a result of pipe line water contamination due to mixing of sewage from a canal. The results add evidence to the epidemiology of hepatitis A in the state and warrant the establishment of an efficient water quality surveillance system.
在印度南部喀拉拉邦科拉姆区瓦迪至韦迪昆努地区沿海地带居住的人群中报告出现甲型肝炎异常病例后,开展了一次疫情调查。疾病发生的时间框架、分布模式以及甲型肝炎感染的潜伏期表明,此次疫情爆发可能是由于一条运河的污水混入管道水所致。这些结果为该邦甲型肝炎的流行病学提供了证据,并证明有必要建立一个高效的水质监测系统。
