厦门市区居民五型病毒性肝炎流行特征

The Epidemic Features of Viral Hepatitis in Xiamen, Fujian

按照全国五型病毒性肝炎血清流行病学调查方案，我市于1992年在居民中进行调查，以家庭为单位整群抽样，将1～59岁居民作为调查对象．共采血样403份，共180户。各型肝炎总感染率为：HAV68．49％、HBV75．43％、HCV4．22％、HDVO．50％、HEV20．60％，HBsAg阳性率11．17％、抗一HBc57．57％、抗一HBs41．94％、HBeAg1．99％。调查揭示市区居民病毒性肝炎血清流行病学的一些特点，如：我市为HAV、HBV、HEV高感染区，HAV、HBV感染有职业分布差异，HAV、HBV、HEV感染有家庭聚集性，HBSAg阳性率无性别差导，年龄分布上呈单峰型，HCV阳性与HBV阳性无明显相关性，而HAV阳性与HEV阳性重叠感染的相关性检验有意义。

According to the unified program of the national hepatitis sero-epidemiological study, an investigation was carried out in Xiamen, Fujian since 1992. 403 serum samples were taken from 180 families, includingpeople aged 1-59 years. The results showed that the infection rates of HAV, HBV, HCV, HDV and HEV were68. 49%,75. 43%, 4. 22%, 0. 5% and 20. 60% respectively. The positive rates of HBsAg, anti-HBs, antiHBC, HBeAg were 11. 17%, 57. 57%, 41. 94% and 1. 99% respectively. The study revealed some of theseroepidemiological features of viral hepatitis in the city: The infection rates of HAV, HBV, HEV were high;The prevalences of HAV and HBV vary with the occupations; The infection of HAV, HBV and HEV showed thefamily clustering. The HBsAg rate showed no sexual difference and only single peak for the curve of age distributi on. The rate of HCV showed no correlation with the rate of HBV. But the relevant study of overlapping prevalence between HAV and HEV showed the correlation significantly.
