Abstract
Hepatitis B and C virus (HBV and HCV) infections remain major public health problems in Egypt and data are needed on risk factors for infection. This study determined the prevalence of anti-HCV and HBV surface antigen seropositivity in Damietta Governorate, Egypt, and evaluated potential risk factors for infection and the impact of HBV vaccination on seroprevalence. A household, cross-sectional study was conducted of 2977 individuals. About 20% were vaccinated against HBV. Only 1.1% were infected with HBV and 9.3% with HCV; both infections coexisted in 12 people (0.4%) (all unvaccinated). The main risk factors for both HCV and HBV were exposure to dental procedures, surgery, stitches, schistosomiasis treatment and contact with infected person. HBV and HCV prevalences in Damietta were lower than the national rate, likely due to the routine compulsory HBV vaccination in those aged < 19 years. There is a need to educate the general population about HBV and HCV transmission routes and avoidance of risky behaviours.
