Ali Derbala Ali Hussein

This work was done to study the prevalence of HBsAg carriage rate and other HB sero markers (anti HBc , 1The Ag , and anti HBe ) as indicators for exposure rate , in Qaliobia Governorate (rural area) toapparently healthy population above 40 years (1989). The relation of HBV infection and bilharziasis was also studied.•The HBs Ag carriage rate is 2.5% among apparently healthy population above 40 years.•The anti HBc rate is 51.5% and the total HB seropositivity rate is 52.0% indicating exposure rate.•To all cases(5 cases) with positive HBsAg, HBe Ag were negative, anti HBe were positive, and anti HBc were positive except one case . Only one case was HBs Ag positive , anti HBc negative, but with HBe Ag negative and anti HBe positive.•Anti delta was done to cases with positive HBs Ag, with prevalence 1% of total individuals (196), but it is 2/5 (40% of HBsAg positive cases).•HBsAg carriage rate is higher four times in males (4.2%) than females (1%) but with no significant difference statistically.•HBsAg carriage rate is not affected by age groups I (40-50 ys), II (51-60 ys) and III (above 60 ys).•Anti HBc and total HB seropositivity (exposure rate) are significantly higher in males (58% and 59% respectively) than in
