1979年,我省病毒性肝炎流行病学抽样调查发现HBsAg阳性率达7.65％(R PHA),据此估计全省约有二百万左右HBsAg无症状携带者。为了解HBsAg携带者的动态变化及造成的长期危害,进一步为乙肝的预防管理提供依据,我们在卫生部病毒性肝炎专题委员会的统一布署下,于1983年9—11月对我省1979年肝炎流行病学调查中查出的HBsAg携带者进行了随访观察,现报告如下。材料和方法一.观察内容: (一)对1979年我省病毒性肝炎流行病学调查时,7个调查点(贵阳市、遵义市、毕节、独山、玉屏、天柱、道真县)发现的380例HBsAg无症状携带者进行随访,了解其动态变化,包括转阴、持续携带以及与慢性肝炎、肝硬化和肝癌的关系。
In 1979, the epidemiological survey of viral hepatitis in our province found that HBsAg positive rate of 7.65% (R PHA), estimated that about 2 million in the province asymptomatic HBsAg carriers. In order to understand the dynamic changes of HBsAg carriers and the long-term harm caused by, to further provide a basis for the prevention and management of hepatitis B, we in the unified deployment of the Ministry of Health virus Hepatitis Committee in September-November 1983 to our province in 1979 HBsAg carriers found in the hepatitis epidemiological survey were followed up and are reported below. MATERIALS AND METHODS A. Observations: (1) In the epidemiological investigation of viral hepatitis in Shaanxi Province in 1979, seven investigation points (Guiyang, Zunyi, Bijie, Dushan, Yuping, Tianzhu, Daozhen) were found 380 cases of HBsAg asymptomatic carriers were followed up to understand the dynamic changes, including negative, persistent and with chronic hepatitis, cirrhosis and liver cancer.
