RESUMO
Disease concepts and medical treatment practices surrounding schistosomiasis haematobium were studied among males in Upper Egyptian villages and towns using interview methods. Most informants considered bilharzia to be a serious disease for which they commonly sought treatment. Its occurrence was attributed primarily to natural causes, particularly various aquatic worms and insects, dirts, excrement, dead animals, toxins and stagnant and vegetated waters, mostly large canals. Contact with water from the Nile river was generally thought to be quite safe. Drug treatment was weakly associated with amount of education. All groups reported use of antischistosomal drugs and plant medicines. Seventy-four per cent of the sample had a treatment history, 64% having taken oral drugs and/or injections, 40% plant medicines and 29% both. Drinking decoctions of damsissa (Ambrosia maritima) was the most commonly used household remedy. Plant materials were usually obtained from fields, gardens and local markets and patent medicines from nearby clinics and private physicians in towns. Recommendations are made for the national mass chemotherapy programme.
