A study was carried out in March/April 1988 to determine the prevalence of Schistosoma haematobium and S. mansoni among schoolchildren in the Jebal ash Sharq District, Dhamar Governorate, Yemen Arab Republic. The average percentage of schoolchildren infected with schistosomies (one or both species) was 34.5%. The prevalence of S. mansoni was found to be 22.6% and S. haematobium was present in 16.8% of the urine samples. A negative correlation was found between prevalence and altitude.
