The prevalence of hepatitis B and C infections among immigrants to a newly reclaimed area endemic for Schistosoma mansoni in Sinai, Egypt.
Serology for hepatitis B and C markers was performed on a community-based random sample of 506 residents of an area recently reclaimed from the desert and endemic for Schistosoma mansoni. The mean age of the study subjects was (20 +/- 14), and 52% were males. The overall seroprevalence of hepatitis B (Anti-HBc and/or HBsAg) was 19.6%, hepatitis C (Anti-HCV) was 10.3%, while 5% were positive for both hepatitis B and C. A strong association was present with increasing age for both hepatitis B and C markers. However, there was no association with either sex, S. mansoni infection or schistosomal periportal fibrosis. Also HBV seropositivity was not associated with increased risk of HCV seropositivity. Anti-HCV seropositivity was significantly associated with previous parenteral treatment for schistosomiasis (OR = 7.9), and with history of previous surgery (OR = 3). Hepatitis B and C are major public health problems in this population. It is recommended to consolidate the Egyptian programme of infant hepatitis B vaccination, and to extend it to older children and high risk adult groups. There is also an urgent need to study more closely the epidemiology, natural history, risk factors and modes of transmission of hepatitis C.
