Nearly 1,000 serum samples were obtained from apparently healthy workers of both sexes in various factories in Beijing during 1988-1989 and were examined for hepatitis B virus infection markers by radioimmunoassay. The overall prevalence (all ages and both sexes combined) of cases positive for HBsAg, anti-HBs and anti-HBc were 3.7%, 36.6% and 37.7%, respectively and the rate of those negative to any of the three markers studied was 56.1%. The infection rate was lower than the values reported early in the 1980s for Beijing populations or the values for populations in other parts of China.
1988 - 1989年期间，从北京各工厂的近1000名貌似健康的男女工人中采集血清样本，并用放射免疫分析法检测乙肝病毒感染标志物。HBsAg、抗-HBs和抗-HBc阳性病例的总体患病率（所有年龄和男女合计）分别为3.7%、36.6%和37.7%，对所研究的三种标志物均呈阴性的比例为56.1%。感染率低于20世纪80年代初报道的北京人群的值或中国其他地区人群的值。
