[Incidence of markers of HBV and HAV infections in workers of the departments and clinics of anesthesiology and intensive care at the medical academy in Wrocław].

The frequency of markers of infection by hepatitis virus A and B was studied among the workers (physicians, nurses, auxiliary personnel) of the Chair and Department of Anaesthesiology and Intensive Therapy, Medical Academy in Wroclaw. Serological tests were done by the immunoenzymatic method using kits of Abbott Diagnostics Division. IgG anti-HAV antibodies were found in 62.8% of the tested subjects. HBV markers were present in 44.3% of the subjects, that is several times more frequently than in the general population. HBsAg carriers accounted for 4.3% of the whole group, while in 40% of the group anti-HBV antibodies were present in various combinations suggesting an immunity against HBV infection.
