通过对ＨＢＶ高感染地区医院职工和当地居民的ＨＢＶ血清学比较研究显示：两组人群无论在总感染率（４４．０５％和４４．８０％）和ＨＢｓＡｇ阳性率方面（１６．６７％和１７．０５％）均无显著性差异（Ｘ１２＝０．０２，Ｐ１＞０．０５；Ｘ２２＝０．２６，Ｐ２＞０．０５，提示在ＨＢＶ高感染地区不存在高危人群的概念。两组人群ＨＢＶ感染的一般特征基本相似。乙型肝炎密切接触史在两组人群中未显示明显的传播作用，可能在ＨＢＶ高感染地区存在“感染阈值”。关键词
HBV serology in hospitals and local residents in areas with high HBV infection showed that in both groups, no significant difference was found in the overall infection rates (44.05% and 44.80%) and HBsAg positive rates (16.67% and 17 .05%) showed no significant difference (X12 = 0.02, P1> 0.05; X22 = 0.26, P2> 0.05), suggesting that there is no concept of high-risk population in high-HBV infected areas. The general characteristics of HBV infection were similar, and the close history of hepatitis B infection did not show any significant transmission in the two groups of patients, which may have an “infection threshold” in HBV-infected areas.
