【Abstract】 In a follow up study of 47 HBsAg families, nine mothers from nine families were subtype adr and three mothers from three families were subtype adw. These 12 mothers had a total of 30 HBsAg positive children of which 21 belonged to the same subtype as their mothers. Seven of the offspring tested positively to a different subtype from their mothers, The subtype of the other two offspring could not be confirmed. These results demonstrate that HBV infection within the household is mainly through family relationships. It also shows, however, that social relationships are also an epidemiological factor.更多还原
