Abstract | BACKGROUND: Rural populations present an elevated risk of exposure to hepatitis A virus. OBJECTIVE: The objective of this study was to estimate the prevalence and risk factors associated with hepatitis A virus infection among residents of rural settlement projects of southwest Goiás, Central Brazil. METHODS: A total of 466 residents were interviewed and tested for the detection of anti- hepatitis A virus antibodies by ELISA. RESULTS: The global prevalence of anti- hepatitis A virus was 82.2%. In individuals aged 5-9 years and 10-19 years, the prevalence was 15% and 58.8%, respectively. Persons in the 10-19 age group, with a history of life in encampments, with more than five people per residence consuming well water, were predictors for exposure to hepatitis A virus. CONCLUSION: Our results suggest that the hepatitis A virus endemicity in rural settlements in southwest Goiás similar to that found in the urban population of the Midwest Region, confirming the implementation of universal hepatitis A vaccination in children.
