Objective:To determine the disease prevalence and its relationship with hepatitis B and C viruses among school children in five endemic areas by schistosomiasis.Methods:During June 2007 and March 2009,1 484 school children aged between 5-16 years participated in the current study from 32 basic schools in five districts(Al-Dhabab,Hedran,Warazan,Al-Barh and Al-Shmaytin) in Taiz Governorate,Republic of Yemen.Out of school children who participated in the study;1 406 stool samples,1 484 urine samples and 214 blood samples were collected and examined.Results:Schistosoma mansoni(S.mansoni) was found in all the studied areas except Al-Barh.However,Schistosoma haematobium(S.haematobium) was recorded only in Al-Shmaytin and Al-Barh.Both S.mansoni and S.haematobium were observed in Al-Shmaytin district.The overall prevalence was 20.76%for S.mansoni and 7.41%for S.haematobium. The prevalence rate of infection among males was higher than females,shwing no significant differences.Rate of light,moderate and heavy infections in the case of S.mansoni were 41.78%, 25.34%and 32.87%respectively.Whereas,for S.hematobium it was 50.90%for light infection and 49.09%for heavy infection.Regarding to the prevalence of viral hepatitis among infected school children with schistosomiasis,it could be noticed that hepatitis B virus was higher than the prevalence of hepatitis C virus.But,the presence of HBsAg and anti-HCV was not associated with Schistosoma infection.Conclusions:Schistosomiasis infection is an important public health problem in Taiz Governorate,Republic of Yemen.There was a correlation between S. haematobium and hepatitis B,but no association between 5.mansoni infections and hepatitis B and C viruses.
