Chronic hepatitis B and liver schistosomiasis: a deleterious association.

Background: Chronic hepatitis B (CHB) and schistosomiasis are prevalent in several countries, but the impact of this association is unknown. We aimed to investigate the prevalence and morbidity of this co-infection in Minas Gerais, an endemic area of schistosomiasis in Brazil.

Methods: In total, 406 adults with CHB (HBsAg positive >6 months) were included in a cross-sectional study.
