Abstract (Summary)
Hepatitis B virus (HBV) infection is an important worldwide public health problem and it has been cause of elevated morbidity and mortality rates. Health professionals are more exposed to HBV contamination. The objectives of this study were determine the prevalence of serological markers of hepatitis B and possible risk factors for this disease in 138 health care workers from six dialysis units at Pernambuco state, northeast Brazil. Blood samples were collected between March and July 2007 and tested for HBV markers: HBsAg, anti-HBs and anti-HBc total by enzyme-linked immunosorbent assay (ELISA) of 3rd generation. An overall HBV infection prevalence determined by presence of markers HBsAg and/or anti-HBc total in professionals of dialysis was 13%. The positive rates of anti-HBs were 75,4 % (104/120). However, 11,6 % (16/120) staff members were susceptible to this infection. Multivariate analysis of risk factors showed that length of employment, the frequency of protection equipments use (EPIs) and incomplete vaccination were significantly associated with HBV seropositivity. This study showed that dialysis units studied have been obeying the control norms and disease prevention. We rebound, however, the necessity of monitoring serological markers, once it?s significative percentual of susceptible professionals to infection by this virus
