【摘要】 对５９６户家庭甲、乙、丙、戊型肝炎病毒感染血清学调查资料进行流行病学分析，发现四型肝炎感染率在不同人口的家庭中分布存在差异。经Ｇ统计量检验，甲、乙两型肝炎感染率家庭聚集有统计学意义（ＨＡＶＴ＝７．３１，Ｐ＜０．０１；ＨＢＶＴ＝２．２５，Ｐ＜０．０５）。随着家庭人口增多，甲、乙两型肝炎病毒感染率在增高。户感染率与户人口数之间存在着正相关（ＨＡＶｒ＝０．９８，Ｐ＜０．０５；ＨＢＶｒ＝０．８０，Ｐ＜０．０５）。家庭聚集率甲型为６３．１３％，乙型为６８．１３％。丙、戊两型肝炎病毒感染家庭聚集现象不显著。此结果对这几型肝炎防治采取针对性措施有一定意义更多还原

【Abstract】 An seroepidemiological study on the HAV,HBV,HCV and HEV infections were carried out in 596 families.The data showed that the distribution of the 4 types of viral hepatitis was different in families with various number of persons.There was a difference of the family clustering among the infectious rates of 4 hepatitis infectious.By using Gtest,there was statistical difference between the family clustering rates of HAV and HBV.There was a positive correlation between the infectious rates of the above two infections and the number of persons in a family.The results did not support that the infection rates of HCV and HEV were related with the number of persons in a family.The authors suggested that these results are useful for hepatitis control.更多还原
