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
Epidemiological analysis of serological survey data of A, B, C and E in 596 families found that there was a difference in the distribution of hepatitis B among families with different populations. The G statistics showed that the incidence of hepatitis A and B infection in the family was statistically significant (HAVT = 7.31, P <0.01; HBVT = 2.25, P <0.05). With the increase of family population, A and B hepatitis B virus infection rates are on the rise. There was a positive correlation between household infection rate and household population (HAVr = 0.98, P <0.05; HBVr = 0.80, P <0.05). The rate of family aggregation was 63.13% and type B was 68.13%. C, hepatitis B virus infection in the family aggregation phenomenon is not significant. The results of these types of hepatitis prevention and treatment to take targeted measures have some significance
