Neglected Tropical Diseases (NTDs) affect over a billion people globally, with schistosomiasis, an acute and chronic disease caused by parasitic worms, remaining a major public health concern in sub-Saharan Africa. Praziquantel, the medication used to treat these infections, donated by Merck through WHO’s drug donation programme, is the cornerstone of Zambia’s fight against schistosomiasis. But challenges in ordering and distribution have led to stock imbalances, expiry risks, and delays in mass drug administration campaigns, threatening the sustainability of the programme.
