To further investigate factors responsible for the recently documented changes in schistosomiasis patterns in the Nile Delta, questionnaire-derived information on antischistosomal drug usage was obtained from a 25% systematic sample of 609 residents of a stable village in the south-central Delta. Ten percent of the population had received antischistosomal drugs during the previous 4 years. Most of the drugs administered were injectable compounds, and 92% of individuals receiving them failed to complete the treatment regimen. Additional sources of information from a village physician, a pharmacist and a major pharmaceutical corporation confirmed and expanded the survey findings, indicating that antischistosomal drug usage cannot explain the recently observed changing patterns of human schistosome infections in the Nile Delta region.
