1988年初春,上海市发生居民因进食产自江苏启东地区甲型肝炎病毒(HAV)污染的毛蚶而发生甲型肝炎(甲肝)暴发性流行。为了解本次甲肝流行的预后,确切统计本次流行中甲肝的死亡率,我们对流行期中死亡的患者进行调查,对死亡率和死亡原因作一分析。 In the early spring of 1988, an outbreak of hepatitis A (Hepatitis A) occurred in Shanghai due to the consumption of hairtail contaminated with Hepatitis A virus (HAV) from Qidong, Jiangsu Province. In order to understand the prognosis of this prevalence of hepatitis A and make an accurate statistics on the mortality of hepatitis A in this epidemic, we investigated the patients who died in the epidemic period and analyzed the causes of death and mortality.
