乙型病毒性肝炎(乙型肝炎)的流行比甲型肝炎多见,临床及予后也都比甲型肝炎严重。为了解乙型肝炎在人群中的分布及HBsAg 携带者的转归,于1978年5—12月对健康人群和 HBsAg 携带者进行血清学调查。
The prevalence of hepatitis B (Hepatitis B) is more common than that of Hepatitis A, and it is also worse than that of Hepatitis A both in clinical and post-treatment. To understand the distribution of hepatitis B in the population and the outcome of HBsAg carriers, a serological survey of healthy and HBsAg carriers was conducted in May-December 1978.
