目的了解目前我市1～59岁人群中甲、乙、丙、戊型肝炎病毒的血清学流行状况。方法采用多阶段随机抽样方法选取研究样本,用ELISA方法检测血清学抗体。结果我市HBsAg、抗-HBs、抗HBC、抗-HAV、抗-HCV、抗-HEV的阳性率分别为3.5%、26.8%、29.6%、71.6%、1.1%和22.1%。HAV、HBV的感染率小年龄组很低;HBV感染率城镇高于农村,感染率较高的职业为行政事业、商业服务业者;抗HEV阳性标本中98.8%抗HAV阳性。结论随着免疫规划的开展,小年龄组HAV、HBV的感染率很低,高暴露人群各型肝炎感染率较高,应继续加强重点人群中病毒性肝炎的防控,强化成人及重点人群的疫苗接种工作。
Objective To understand the seroprevalence of A, B, C and E hepatitis viruses among people aged 1- 59 in our city. Methods The multi-stage random sampling method was used to select the study samples and the serological antibodies were detected by ELISA. Results The positive rates of HBsAg, anti-HBs, anti-HBC, anti-HAV, anti-HCV and anti-HEV in our city were 3.5%, 26.8%, 29.6%, 71.6%, 1.1% and 22.1% respectively. HAV, the infection rate of HBV in the small age group is very low; the infection rate of HBV in urban areas is higher than that in the rural areas, and the occupations with high infection rate are administrative and commercial service providers; 98.8% of anti-HAV positive in anti-HEV positive specimens. Conclusions With the development of immunization programs, the infection rate of HAV and HBV in the small age group is very low, and the infection rate of various types of hepatitis in high-exposure groups is high. Prevention and control of viral hepatitis in the key population should be continued to strengthen the Vaccination work.
