title: Hepatitis B surveillance: 4-year survey of staff in a National Blood Transfusion Service.
abstract: The prevalence of HBsAg and anti-HBs in personnel of the Canadian Red Cross Blood Transfusion Service (BTS) during 1979 was not found to be significantly different from that of staff first employed in 1978-1979 or from that found among voluntary blood donors. Between 1976 and 1979, 2525 individuals were tested, of whom 13 seroconverted to HBsAg-positive; 54% of these cases appeared to be accident-related. During the same period 29 staff developed anti-HBs; of these 21% were apparently accident-related. Actual rates of seroconversion were not calculated because of staff turnover. The data suggest that BTS employees do not constitute a 'high-risk' group.
