One hundred and sixty five Korean women in a shoe factory in Masan, Korea were evaluated on hepatitis B virus infection by solid-phase radioimmunoassay in 1986. The participants were women of child-bearing ages, mostly in 20's and 30's. About two thirds (105/165) of the subjects had serological evidence of past or present hepatitis B virus infection, and 17% (28/165) were HBsAg-positive. In view of possible risk of vertical transmission of hepatitis B virus, further epidemiological study was considered necessary to establish preventive measures.
