Past and present situation of human fascioliasis in Dakahlia Governorate, Egypt.

Zoonotic fascioliasis is a problem not only in Dakahlia Governorate, but also in other Egyptian Governorates. This work was conducted in ten centers at Dakahlia Governorate, Egypt. Three thousand cases were randomly selected annually from each center representing five rural and five urban areas. Cases were examined for Fasciola infection by stool examination using, direct smear, formol ether sedimentation and Kato-Katz technique. Infection was higher in rural areas than urban areas. Female /male ratio was 1.5:1. Children between five and ten years old represent the highest infected group. The prevalence of infection was more among illiterate compared to educated individuals examined. Remarkable reduction in the prevalence rate was recorded in the last year of study compared to previous years, which is a good index of excellent control measures conducted by the Egyptian governorate to overcome parasitic infections.
