In Africa, schistosomiasis prevalence is second only to malaria. The disease overwhelmingly affects the poor, and often strikes people who are forced by their conditions to work in water where the schistosomes reside in intermediate snail hosts.
Demand for praziquantel is highest in African countries where the disease is endemic. However, demand is surging due to increased awareness about the disease and availability of treatment. the success of the Schistosomiasis Control Initiative in the East African countries (Uganda, Republic orf Tanzania, and Zambia) has led more people to demand treatment (2). While many people were previously unaware that they were infected with the disease or were unable to receive a propoer diagnosis, many now recognize that treatment is available. People have reported significant improvements in health after taking drugs that have become readily available, leading to increased demand for treatment.
The success of the current SCI program, with over 1.5 million people treated in Uganda alone as of 2005, has led a number of other countries to prepare a national plan and appl to SCI to roll out similar worm control initiatives. The countries include: Burkino Faso, Cameroon, Ghana, Kenya, Malawi, Mali, Niger, and Nigeria.
