【Abstract】 This paper reports the sequential change of HBV infection markers in 138 pupils at a primary school in Daxing County, Beijing. Our investigation established that the total infection rate of HBV in 1983 was 55.8% and the annual average new infection rate to 1986 was 7.3%. During a period of 36 months, six cases in which HBsAg was positive were observed. The negative conversion rate was 33.3%. We found that the HBsAg titre, the anti-HBe titre, and positive or negative results of HBeAg in carriers of HBsAg bore a close relationship to conversions. The patients with positive HBsAg were all of the adr subgroups.更多还原
