Urinary schistosomiasis: options for control within endemic rural communities: a case study in south-west Nigeria.

A preliminary investigation was conducted into factors that may bring about control of morbidity due to endemic urinary schistosomiasis in rural communities. A Knowledge, Attitudes, Practices and Beliefs (KAPB) study was conducted among primary schoolchildren (those with more than four years elementary education) in Ogbagba village, Osun State, Nigeria, from October 1990 to December 1993, to ascertain their understanding of urinary schistosomiasis. The study further assessed the potential of subjective haematuria, i.e. asking children with haematuria in the recent past to so indicate, in detecting urinary schistosomiasis. It was established that subjective haematuria is both sensitive and specific for detecting urinary schistosomiasis in endemic communities. The study also established that subjective haematuria offers a valid, easy to recognize target for morbidity control in endemic situation. It is proposed that with appropriate health education; availability of safe, effective, easy-to-administer drugs, such as praziquantel, morbidity control of urinary schistosomiasis is feasible within the primary health care system with the lower cadre health worker or even a volunteer village health worker (VVHW) at the centre of the control effort.
