Seroprevalence of viral hepatitis in riverine communities from the Western Region of the Brazilian Amazon Basin

Prevalence and genotyping of hepatitis C virus in blood donors in the state of Pará, Northern Brazil

“…Epidemiological studies on the prevalence of antibodies to HCV have been conducted in certain populations in the Northern region of Brazil (Soares et al 1994, Ferrari et al 1999, De Paula et al 2001, Tavares-Neto et al 2004, El Khouri et al 2005. We found a seroprevalence of antibodies to HCV of 0.22%.…”

“…In Northern Brazil, the seroprevalence among blood donors has been determined in the states of Acre (AC) (5.9%), Pará (PA) (0.5-2%), Roraima (1.2%) and Amazonas (AM) (0.8%) (GESBH 1999, Da Fonseca & Brasil 2004. Epidemiological studies conducted of indigenous, riverside and immigrant populations in Northern Brazil indicate a range of 0.38-2.4% seroprevalence (Soares et al 1994, Ferrari et al 1999, De Paula et al 2001, Tavares-Neto et al 2004, El Khouri et al 2005.…”
