Serum samples were investigated from 213 health service workers in Szczecin with a particular exposure to infection with HBV. In 5 samples (2.34%) the HBs antigen was demonstrated, and 120 workers (56.33%) anti-HBc antibodies were present. History data showed that only one-fifth of them had had a manifest form of virus hepatitis, thus the asymptomatic infection prevailed. After one year the investigations were repeated in 62 subjects who had had no HBV markers in the first determination and seroconversion was demonstrated in 11 of them (17.74%).
