HBV infection risk in hospital workers

Prevalence of HBV infection markers and its association with some risk factors has been studied on hospital staff of the University Polyclinic of Palermo. The results show that male sex, job category (technicians, nurses, cleaners) and age are significantly associated with a higher prevalence of HBV infection markers; length of service and working in departments with a presumably higher exposure to blood did not result as a risk factor of higher prevalence of HBV infection when submitted to multiple regression logistic analysis. It is suggested that results of this study may be affected by the elevated spread of HBV infection in this area, and extra risk associated to hospital exposure is too small to be demonstrated.
