在世界范围我国属于肝炎高发区。1979～1980年病毒性肝炎全国用血凝法流行病学调查结果现患率为2.77%,HBsAg、抗-HBs的阳性率为8.83%及3.47%。1987年在河北正定县调查病毒性肝炎非甲型肝炎(主要为乙型肝炎)患病率0.91%;在无甲肝流行年发病率为103/10万,有甲肝小流行年达253/10万;肝病死亡率为20～22/10万。用ABBOTT放免药盒检测HBsAg、抗-HBs及抗-HBc的阳性率分别是11.4%、32.1%、58.4%(孙永德,等,1987汇编)。以上资料表明我国乙型肝炎感染是严重的。为防治病毒性肝炎,现将1983～1988年肪治肝炎的成果简述如下。
In the world, our country belongs to the high incidence of hepatitis. The incidence of viral hepatitis from 1979 to 1980 in China was 2.77%. The positive rates of HBsAg and anti-HBs were 8.83% and 3.47% respectively. In 1987, Zhengding County, Hebei Province, investigated the prevalence of non-A (non-A) hepatitis B virus (mainly Hepatitis B) at a rate of 0.91%; in the year of a non-HAV prevalence was 103 / 100,000, with a Hepatitis A ; Liver disease mortality rate is 20 ~ 22/100000. The positive rates of HBsAg, anti-HBs and anti-HBc detected by ABBOTT kit were 11.4%, 32.1% and 58.4%, respectively (Sun Yongde, et al., 1987). The above data show that hepatitis B infection in China is serious. For the prevention and treatment of viral hepatitis, now the results of the 1983 to 1988 treatment of chronic hepatitis are as follows.
