First in a series of manuals covering crucial aspects of monitoring and evaluation. Public health interventions using preventive chemotherapy to control neglected tropical diseases(NTDs) depend on people in endemic areas receiving the medicines or drugs they need in the places where they live, at appropriate regular intervals. After making arrangements to ensure access to such drugs, program managers must be able to follow the progress of the intervention. The first and fundamental step in the process consists of monitoring drug coverage when the drugs are swallowed by individuals at the point of delivery. Managers must know how many people in need of treatment received the treatment when and where it was offered. WHO, 2010.
