Abstract: We investigated the seroprevalence of hepatitis A virus (HAV) and hepatitis E virus (HEV) infection in subjects living in the community of Manguinhos, Rio de Janeiro, Brazil, and assisted Key words: hepatitis A virus -hepatitis E virus -seroprevalence -epidemiology -Rio de Janeiro -Brazil Viral hepatitis is a public health problem worldwide. Two of the agents that cause viral hepatitis are enterically transmitted: hepatitis A virus (HAV) and hepatitis E virus (HEV).In the last years, improvements in environme… Show more

“…In these countries the prevalence ranged from 3.0% in Southeast Brazil (12) to 10.5% in Mexico (1). Although serological evidences of HEV presence in Brazil have been published (6,8,12,22,29,42), until this report, molecular characterization of HEV isolates circulating in Brazil has not been done.…”

“…As a consequence, increasing proportions of those populations have had no contact with HAV and are therefore more susceptible to infection. In Brazil, hepatitis A is still considered an endemic disease, although data collected in the state of Rio de Janeiro indicate that a shift in the hepatitis A epidemiological pattern has taken place (Santos et al 2002, Villar et al 2002. …”

“…Other studies performed in the Southeastern region of Brazil have shown lower seroprevalence rates, especially when groups with higher socioeconomic status were analyzed 10,20,23 . By contrast, studies performed in the Northern region showed a 86.4% seroprevalence of hepatitis A among children from two to nine years (n = 487) 3 , and 90.9% in riverine children from 0 to 10 years old (n = 22) 16 .…”
