title: Characteristics of HBsAg subtypes distribution in Beijing area.
abstract: This paper reports that 300 HBsAg positives were distributed in 262 families. 14 of the 262 families had two or more HBsAg positives. In the 14 families, 7 showed the same subtype HBsAg, probably due to HBV infection from family source. Another 7 families showed HBsAg of different subtypes, definitely due to infections from the community.
