Serological markers for evidence of past exposure to hepatitis B virus (HBV) and hepatitis C virus (HCV) were investigated in a cohort of refugees from Mozambique. Serological markers for past exposure to HBV were detected in 56% of the population and, in addition, 13.2% carried the HBV surface antigen. Anti-HCV antibodies could be confirmed in 3.2% of the population and occurred mostly in the older individuals. Only one anti-HCV antibody positive individual was positive for HBsAg. Immunity to rubellavirus had reached 85% by 11 years of age.
