自从1968年明确了肝炎协同抗原(Hepatitis Associated Antigen,以下简称HAA)与乙型病毒肝炎的关系以来,国内已有较多流行病学调查及临床资料发表,但迄今有关儿科方面的资料并不多见。以往国外一般认为儿童时期的病毒性肝炎主要属于甲型(即传染性肝炎),而乙型(即同种血清性肝炎)少见,儿童时期的抗原携带者更为罕见。为了对儿童中乙型肝炎传布情况获得较为明确的概念,以利今后的肝炎防治工作,我科于1973年3月起,对部分健康儿童及门诊和住院病儿进行了肝炎协同抗原的调查工作。
Since the relationship between Hepatitis Associated Antigen (HAA) and Hepatitis B virus has been clarified in 1968, there have been more epidemiological investigations and clinical data published in China, but so far the data on pediatric diseases are few see. In the past, it was generally considered that viral hepatitis in childhood mainly belongs to type A (infectious hepatitis), while type B (ie, allogeneic hepatitis) is rare, and childhood antigen carriers are even rarer. In order to obtain a clearer concept of transmission and distribution of hepatitis B among children, in order to facilitate future prevention and treatment of hepatitis, our department conducted a survey on hepatitis co-antigen in some healthy children and outpatients and inpatients as of March 1973 .
