研究乙型肝炎的传播因素是杜绝乙肝蔓延的基础。为了解旅客列车能否成为乙肝的传播因素,我们于1990年10月用RPHA法对管内9/10、97/98、307/308、521/522、527/528次10组部份列车车厢扶手及茶几表面作了HBsAg污染的调查。共采样300件,其中9组11件检出HBsAg,其检出率为3.67％。观察不同车种时,发现普客的检出率最高达5.00％,普快3.33％,特快
Study of hepatitis B transmission is to prevent the spread of hepatitis B basis. In order to understand whether passenger trains can become a factor in the transmission of hepatitis B, we conducted the RPHA method in October 1990 on the 9 / 10,97 / 98,307 / 308,521 / 522,527 / 528 train sets of 10 train handrails And the surface of the coffee table HBsAg pollution survey. A total of 300 samples were collected, of which 11 were detected in 9 groups HBsAg, the detection rate was 3.67%. When observing different vehicle types, it was found that the detection rate of up to 5.00% of general passenger, general fast 3.33%, Express
