为了研究福建省肝炎病毒感染的家庭聚集性，应用二项分布分析法，对福建省９个疾病监测点正常人群中１２３７户家庭的抗－ＨＡＶ、ＨＢｓＡｇ、抗－ＨＣＶ、抗－ＨＥＶ阳性分布进行分析。结果显示，除了抗－ＨＣＶ外，抗－ＨＡＶ、ＨＢｓＡｇ、抗－ＨＥＶ二项式分布χ２值分别为４９．８９、２１７．９１、２７．３９，Ｐ值均小于０．００１，表明均有极明显的家庭聚集性，聚集率分别为８４．１３％、３４．８３％和３５．２３％。研究结果提示，家庭聚集性主要是母婴传播和家庭内水平传播，ＨＥＶ感染存在性传播迹象
In order to study the familial aggregation of hepatitis B virus infection in Fujian Province, the distribution of anti-HAV, HBsAg, anti-HCV and anti-HEV was detected in 1237 families in the normal population of 9 disease surveillance sites in Fujian Province by binomial distribution analysis analysis. The results showed that in addition to anti-HCV, anti-HAV, HBsAg, anti-HEV binomial distribution χ2 values were 49.89,217.91,27.39, P values were less than 0.001, indicating that both have extremely Significant family aggregation, aggregation rates were 84.13%, 34.83% and 35.23% respectively. The results suggest that family aggregation is mainly mother-to-child transmission and horizontal transmission within the family, signs of sexual transmission of HEV infection
