A focus of human fascioliasis in the Nile Delta, Egypt.

This study was carried out in Abis II village. A representative sample of the population was examined for parasitic infections. Of these 40 cases were positive for Fasciola ova and the diagnosis was confirmed. The prevalence of fascioliasis was 7.3 per cent. The egg size was determined in both human and animal samples. Although the ova measurements corresponded in many instances to Fasciola hepatica, yet the identification of the Fasciola spp. needs further investigations.
