通过对湖北省钟祥县官庄湖农场一般人群进行3年后复查,比较各种类型乙型肝炎感染携带者对家庭易感接触者的传染性大小。结果:3年后HBV续发感染率为40.45％,HBsAg,抗-HBs、抗-HBc、HBeAg及抗-HBe分别为1.37％、2.73％、29.55％、5.28％和14.91％。家中上次有HBV感染或抗-HBc感染对易感接触者续发抗-HBc感染的传染性增加,有HBsAg感染的易感接触者续发HBeAg感染危险度增高,而上次有抗-HBc感染的家庭的易感接触者HBeAg续发感染减少。
The general population of Guanzhuang Lake Farm in Zhongxiang County of Hubei Province was reviewed after 3 years to compare the contagious size of carriers of various types of hepatitis B in susceptible families. Results: After 3 years, the rate of HBV infection was 40.45%. The rates of HBsAg, anti-HBs, anti-HBc, HBeAg and anti-HBe were 1.37%, 2.73%, 29.55%, 5.28% and 14.91% respectively. The last infection with HBV or anti-HBc in the family increased in contagious anti-HBc infections in susceptible contacts, and the risk of subsequent HBeAg infection was increased in susceptible contacts with HBsAg infection, whereas the last with anti-HBc Susceptible contacts in infected families have reduced HBeAg infection.
