江苏省甲肝防治对策及其效益评估

流行病学调查显示,始于１９８８年江苏省病毒性肝炎高发是由甲型肝炎春季流行高峰所致。其危险因素包括：人群甲肝抗体水平降低、生食海产品和有接触史等。为使发病强度得到控制,自１９９４年起采用以接种甲肝疫苗为主导措施的防治对策,每年全省开展“压春峰”活动。该对策取得显防病效果,６年间共减少发病６５２８７９例,发病强度从全国第一位降至全国平均水平以下,急性肝炎病例中甲肝病例比例下降,甲肝爆发点显减少,６

The Preventive Measurements of Hepatitis A in Jiangsu Province and Its Benefit Cost Ratio Analysis

The epidemiological survey showed that the high incidence of viral hepatitis in Jiangsu started in 1988 was resulted from the high peak of epidemic hepatitis A in spring time. The inducing factors include low level of antibody of hepatitis A, intake of raw sea food and contact history. To control the incidence of hepatitis A. immunization of hepatitis A with vaccination was taken as the preventive measures since 1994 in the whole province to reduce the high incidence in spring. We have obtained remarkable effect. The total number of infected patients were cut down by 652.879 cases during last 6 years. The incidence reduced from the top in the country to a level under average. Among the cases of acute hepatitis ,the incidence of hepatitis A dropped yearly. The outbreak points of hepatitis A markedly decreased. The conclusion based on the above shows the direct ecomonic loss reduced 1 . 305. 758 million yuan and the indirect loss reduced 780. 483 million yuan. The vaccination cost was 288. 30 million yuan. The benefit cost ratio is 7. 24. Our conclusion is that the preventive measures to control the "spring peak" of hepatitis A are quite effective with low cost.
