title: Hepatitis B antigen-positive obstetric patients.
abstract: In a period of six years (1971--77) 9400 sera taken at booking from antenatal patients were examined for hepatitis B antigen (HBsAg), and 40 patients were positive. These 40 patients had 45 pregnancies and were treated with special precautions so far as venepuncture and the management of delivery were concerned. No member of the hospital staff dealing with the patients developed hepatitis B. All infants born to these mothers were normal, two infants were HBsAg-positive at 7 months and 2 years, but are clinically well. No obstetric problems attributable to the HBsAg-positive state were encountered.
