目的了解江苏省农村散发性戊型肝炎的流行病学特征。方法通过建立覆盖市、镇、村三级医疗卫生服务机构的疑似肝炎主动监测网络,系统全面地监测戊型肝炎病例的发病情况。结果主动监测网络的敏感性明显高于网络报告系统,能更加准确、全面地掌握戊肝的发病规律。结果显示戊型肝炎病例占疑似急性肝炎病例的26.7%,男性戊肝发病率高于女性(P<0.01);发病随着年龄增长而上升,多见35岁以上人群;全年均有发病,冬春季节较高;戊型肝炎病毒株HEV1、4型并存,但以HEV4型为主(92.5%)。结论疑似肝炎主动监测系统数据显示目前戊肝发病率有被低估的风险。
Objective To understand the epidemiological characteristics of sporadic hepatitis E in rural areas of Jiangsu Province. Methods By establishing a network of suspected hepatitis active health care covering the municipal, township and village medical services, a systematic and comprehensive monitoring of the incidence of hepatitis E cases was conducted. Results The sensitivity of proactively monitoring the network was significantly higher than that of the network reporting system, and the pathogenesis of hepatitis E could be more accurately and comprehensively grasped. The results showed that hepatitis E cases accounted for 26.7% of the cases of suspected acute hepatitis, the incidence of hepatitis E in males was higher than that in females (P <0.01); the incidence increased with age, more common in people over 35 years old; Hepatitis E virus strain HEV1, 4 co-exist, but HEV4 type (92.5%). Conclusions The data from the active hepatitis A surveillance system show that the prevalence of hepatitis E is underestimated.
