Abstract
PURPOSE OF THE STUDY: The purpose of this study was to screen for hepatitis B virus (HBV) in Maracan~ a stadium construction workers. It is part of the ‘Ball begins with B and Champion with C’ campaign that started in July 2012, with the objective of analyzing 12 stadiums that will be part of the World Cup in 2014 and were under construction/renovation. METHOD: Out of the 5500 construction workers, 1200 were tested for HBsAg. Sera from HBsAg positive patients were collected for additional tests. Sequencing of the HBV polymerase was carried out in the DNA Sequencing Platform PDTIS/FIOCRUZ, using BigDye Terminator model 3730 (Applied Biosystems, Foster City, CA). HBV genotyping and subtyping are been conducted by using phylogenetic analyses. SUMMARY OF RESULTS: From the 1200 individuals analyzed, 8 (0.6%) were HBsAg positive. Serum HBV-DNA was detectable in 6/8 (75%) patients and all these six patients were anti-HBe positive. All of them were male with mean age of 50 years. CONCLUSION: The prevalence of HBV in the Maracan~ a construction workers was lower. The most probable route of transmission was the injection in the army in the 80’s decade. None of them heard about viral hepatitis. This kind of campaign is very important to prevent and educate the population.
