摘要
目的进一步掌握我市甲型肝炎疫情动态,预测甲肝流行趋势,以便制定有效的防治措施和应急预案。方法对1990～2003年甲肝发病情况和流行特征进行分析。并随机抽查2000年及2002年本市健康居民1370名,检测甲肝病毒抗体水平。结果1990～2003年间,我市甲肝发病率波动在1.44/10万～124.42/10万,年均发病率为57.58/10万,于1991年出现流行高峰,以后呈逐年下降趋势,近几年来基本呈散发状态;全年均有发病,春季为高峰;城市发病率明显高于农村;年龄以儿童为主,男性多于女性。小年龄组抗体阳性率较低。结论我市存在甲肝流行的潜在危险性。应加强小年龄组甲肝防治措施,尤其应加强流动人口较多的城市地区的防治措施。
Objective This study was designed to get a further insight into the epidemic situation of hepatitis A in Qingdao city to benefit to the prediction of its epidemic trends and the formulation of effective preventive and therapeutic measures and emergency plans. Methods The incidence and epidemic characteristics of hepatitis A from 1990 to 2003 were analyzed. Meanwhile, 1370 healthy residents were randomly selected in 2000 and 2002, with their antibody levels of hepatitis A determined. Results The incidence of the disease in Qingdao city ranged from 1.44 to 124.42 /100,000 with an average of 57.58 of 100,000. There was an epidemic peak in 1991, and then a decrease trend of the incidence was seen year after year. There have been only sporadic cases in recent years, with individual cases observed all around the year. In spring, the incidence peaked and it was much higher in the city than in the countryside. Children were mostly involved with males affected more than females. The rate of positive antibody in younger age group was rather lower. Conclusion There is a potential risk of hepatitis A spreading in Qing Dao City. And the prevention and treatment for younger age group should be taken seriously and particular attention should be paid to the cities and regions where there are more floating population.
