摘要
目的了解北京地区戊型肝炎（戊肝）病毒感染现状。方法采用EIA诊断试剂检测人群、猪和鸡血清中戊肝病毒（HEV）抗体。结果1208份人群血清中有260份HEV－IgG抗体阳性，总阳性率为21．52％，对260份HEV IgG阳性血进行IgM抗体检测，有22份阳性，占8．46％。32份猪血清中有15份阳性，阳性率为46.88％，34份鸡血清HEV抗体全部为阴性。人群不同年龄组HEV抗体阳性率依次为11～20岁为5．60％（14／250），21～30岁为20％（42／210），31～40岁为24．03％（62／258），41～50岁为26．44％（78／295），51～60岁为32．82％（64／195），男女不同性别HEV感染率比较，男性阳性率为29．51％（144／488），女性为21．70％（102／470）。结论北京地区人群和与人接触密切的家畜猪均存在戊肝病毒感染，人群戊肝病毒感染率随年龄增长而升高，尤其是男性戊肝病毒感染率明显高于女性，郊区流动人群戊肝病毒感染率明显高于市内人群，家畜猪感染率是人群的2倍以上。
Objective To investigate the seroprevalenee of HEV infection in human population, swine and chicken in Beijing region. Methods EIA was used for detecting anti-HEV IgG of the serum samples. All samples were collected in 2006-2007 in Beijing areas. Results The anti-HEV IgG was detected positive in 21.52% of human （260/1208）, 46.88 % （15/32） of swine, but was negative in chickens （0/24） . The positive rate of human at different age group, was 5.60% （14/250）of 11-20 year, 20% （42/210）of 21-30 year,24.03% （62/258）of 31-40 year, 26.44% （78/295） of 41-50 year, 32.82% （64/195）of 51-60 year. The male（29.51% ） was higher than the female （21.70%） . Conclusion The HEV infection was correlation with age and sex significantly. The infection rate was increased with age, the positive rate in swine was more double than the human population.
