[Seroepidemiological study of HBV infection in Hunan area].
A seroepidemiological study of HBV infection was carried out in a "normal population" of 3,089 in Hunan area by means of SPRIA and ELISA in 1983-1986. The positivity rates of HBsAg, anti-HBs and anti-HBc were 17.87%, 31.76% and 73.03% respectively. The overall rate of HBV infection was 80.77%, All the positive rates of HBsAg, anti-HBs and anti-HBc peak at the age of 10-15 years, then, it remains on a similar level. This results indicate that Hunan is a high epidemic area of HBV and the age of persons at peak infection rate is very young. About half of HBsAg positive persons is HBeAg positive and a part of persons who are both HBsAg and HBeAg positive has the lesion of liver function. Thus these persons could be the reservoirs of HBV infection and it was necessary to treat and deal with them seriously.
