Various strategies have been proposed to control and prevent the infection, but for the adoption of effective control measures, a thorough understanding of the disease epidemiology is necessary. To establish this pathology scenery in Mato Grosso do Sul state, a retrospective study was carried out by the analysis of all requisitions for hepatitis B serology diagnosed by Central Public Health Laboratory, LACEN/FUNSAU/MS, from 1997 through 2003, when was founded that 71.1% of all cases were concentrated in the municipalities of Campo Grande, Dourados, Três Lagoas, Coronel Sapucaia, São Gabriel do Oeste, Naviraí, Ivinhema, Maracaju, Caarapó and Sonora. The available literature was analyzed, focusing the hepatitis B transmission, as an occupational risk in healthcare workers from different professional categories who works in a public primary care network. A total of 332 healthcare workers, from the municipalities mentioned above participated, with grate female predominance (86.7%) and mean age of 39 years. All healthcare workers declared that they had received at least one dose of vaccine, and 75.3% showed titer of Anti-HBsAg = 10 UI/ml. Serological markers of HBV infection were found in 11.1% of the samples. The highest positive rate (51.3%) was found in nursing technicians and auxiliaries. The exposure risk to this infection was identified by 53.6% of the participants and the most frequent occupational accident was a needle stick.
