The relative prevalence of hepatitis B surface antigen (HBsAg), anti-HBs, and anti-hepatitis B virus core antigen (HBc), as markers of hepatitis B virus infection, among 1,866 apparently healthy residents of two Egyptian provinces representing Upper and Lower Egypt populations was determined using solid-phase radioimmunoassay (SPRIA). The prevalence rate of HBsAg in the Egyptian population was moderately high (10.1%); it was higher in the Upper Egypt (11.7%) than the Lower Egypt (8.0%) population and more frequent in young adults--especially those of Upper Egypt--and males than females in both populations. The prevalence of anti-HBs gradually increased with age; it was higher in the Lower Egypt (51.1%) than the Upper Egypt (41.7%) population, and it was higher in females than males. A remarkably high infection rate, as shown by the prevalence of anti-HBc, was found in both populations (88.0%), with minor variations depending on age, sex, and geographic area.
采用固相放射免疫分析法（SPRIA）测定了代表埃及上埃及和下埃及人群的两个省份中1866名表面健康居民的乙肝表面抗原（HBsAg）、乙肝表面抗体（抗-HBs）和乙肝核心抗体（抗-HBc）作为乙肝病毒感染标志物的相对流行情况。埃及人群中HBsAg的流行率中等偏高（10.1%）；在上埃及人群（11.7%）中高于下埃及人群（8.0%），且在两个群体中，年轻人——尤其是上埃及的年轻人——以及男性中的流行频率高于女性。抗-HBs的流行率随年龄逐渐升高；在下埃及人群（51.1%）中高于上埃及人群（41.7%），且女性高于男性。两个群体中抗-HBc的流行率均显示出极高的感染率（88.0%），因年龄、性别和地理区域的不同存在细微差异。
