ABSTRACT
This work aimed at studying time and geographical patterns of schistosomiasis Minia and Qualubia governorates during the last ten years. The data available at Ministry of Health [MOH] for the two governorates were manipulated. Moving average was used to clarify the real peaks or drops in prevalence by smoothing of curve. Results showed a gradual decrease overall trend of S. heamatobium prevalence overtime in Minia governorate with a peak in 1989. However, the prevalence goes up and down with peak in winter months. Epidemic-logic trend of schistosomiasis prevalence in Qualubia governorate showed low fluctuating prevalence with more or les stationary course allover the studied period [1987-1991] with the characteristic peak at early 1989. However, the manoni/haematobium ratio varied greatly between different districts
