目的:调查了解嘉善县戊肝病毒在不同人群中的感染状况和分布规律,对相关危险因素进行探讨,为防制戊肝提供科学依据。方法:2014年对嘉善县不同人群共752人开展HEV-IgG抗体检测与分析。结果:2014年嘉善县752人中HEV-IgG抗体阳性为350例,阳性率为46.54%;阳性率男性(54.31%)高于女性(41.00%),P<0.01,并随着年龄的上升而逐步上升(P<0.01);高危职业人群抗-HEV IgG阳性率为71.86%,职业体检人群抗-HEV IgG阳性率为38.81%,普通农村居民抗-HEV IgG阳性率为40.00%,不同行业人群间的差异有统计学意义(P<0.01)。结论:嘉善县不同人群中HEV感染率均较高,特别是饮食业、饲养业、动物(主要为猪肉及猪内脏、禽类)贩卖等高危职业人员的HEV感染率非常高,这些人群应作为重点防护对象。
Objective: To investigate and understand the infection status and distribution of hepatitis E virus in different populations in Jiashan County, to explore the related risk factors and to provide a scientific basis for the prevention of hepatitis E. Methods: In 2014, 752 persons from different population in Jiashan County were tested for HEV-IgG antibody. Results: The positive rate of HEV-IgG antibody in 752 persons was 46.54% in 2014 in Jiashan County, while the positive rate was 54.31% in women (41.00%), P <0.01. With the increase of age (P <0.01). The positive rate of anti-HEV IgG in high-risk occupational groups was 71.86%, the positive rate of anti-HEV IgG in occupational health examination population was 38.81%, and the positive rate of anti-HEV IgG in ordinary rural residents was 40.00% The difference was statistically significant (P <0.01). Conclusion: The prevalence of HEV infection among different population groups in Jiashan County is high. In particular, HEV infection rates among high-risk occupational workers in the catering industry, breeding industry and animals (mainly pork and pig offal, poultry) are very high, and these groups should be regarded as key protection Object
