Resumo
To assess the prevalence of hepatitis C virus infection among men who have sex with men
(MSM) in Central Brazil, a cross-sectional study was conducted in the City of Goiânia, Central
Brazil, using Respondent-Driven Sampling (RDS). All serum samples were tested for anti HCV and also for alanine aminotransferase (ALT). Anti-HCV positive samples and/or those
with elevated ALT were tested for HCV RNA and genotyped. Ofthe 522 participants,four were
found to be anti-HCV positive, and one was also HCV RNA positive (active HCV infection).
Elevated ALT was found in 14 individuals. Of these, one showed evidence of acute HCV
infection (HCV RNA positive and anti-HCV negative). Therefore, five MSM were positive for
either anti-HCV and/or HCV RNA, giving a crude overall HCV prevalence of 1.0%; 1.3% (95%
CI: 0.3–5.5) after being weighted by RDSAT. All five individuals reported high-risk sexual
behaviors, including two who showed evidence of active HCV infection (genotype 1, subtypes
1a and 1b). Although the study population reported high-risk sexual practices, HCV infection
was not more frequent in MSM than in the general Brazilian population.
