【摘要】 <正> 近年来,随着国内对乙型肝炎病毒(HBV)感染标记敏感方法的建立和普及,对我军乙型肝炎的流行情况已有不少单位做过调查研究,但大多数局限于乙型肝炎某一感染标记的一次性(横断面)调查,系统、动态地观察部队中乙型肝炎流行情况的调查报告甚少。为此,我们以某校为观察点,自1983年12月至1985年7月,进行了为期一年半的调查研究,现将乙型肝炎的观察结果报告如下。更多还原

【Abstract】 Two thousand and fifty three persons were observed in December 1983. The positivity rate of HBsAg,anti-HBs, anti HBc and HBV infection rate were 8.2% , 32.0%, 41.2% and 53.1% respectively. Except HBsAg, the positive rates of anti-HBs, anti-HBc and HBV infection increased with growing of the age. The positivity rate of HBsAg of males was significantly higher than that of females. The positivity rate of anti-HBs turned out contrary to that of HBsAg. The positivity rate of anti-HBc and HBV infection rate were not significantly different between two sexes. The HBV infection rates of populations came from distinct provinces were significantly different. General speaking, the rate in the South was higher than that in the North. Six hundreds twenty and three persons of 2053 were followed up one and a half years. The incidence density of HB was 2.5/1000 person year (31/402.16 person-year). All thirty one persons were subclinically infected with HBV. We also observed that the pattern of HBV infection in a certain population was that of a two-way process.更多还原
