Abstract: A population-based survey to provide informa-tion on the prevalence of hepatitis viral infection and the pattern of risk factors was carried out in the urban population of all Brazilian state capi-tals and the Federal District, between 2005 and 2009. This paper describes the design and meth-odology of the study which involved a popula-tion aged 5 to 19 for hepatitis A and 10 to 69 for hepatitis B and C. Interviews and blood samples were obtained through household visits. The sample was selected using stratified multi-stage cluster sampling and was drawn with equal probability from each domain of study (region and age-group). Nationwide, 19,280 households and ~31,000 residents were selected. The study is large enough to detect prevalence of viral infec-tion around 0.1% and risk factor assessments within each region. The methodology seems to be a viable way of differentiating between distinct epidemiological patterns of hepatitis A, B and C. These data will be of value for the evaluation of vaccination policies and for the design of control program strategies.
