As countries experience success in expanding programs targeting NTDs and meeting initial programmatic goals, new targets require more precise and thorough efforts to identify remaining populations in need of treatment. Therefore, there is a need to develop strategies to improve the quality of information on the geographic distribution of these infections.

• For onchocerciasis, the shift in program goals from control to elimination has necessitated the development of new mapping strategies for areas that were previously not thought to need intervention. New mapping strategies are also required to support implementation decisions in areas where co-endemicity with Loa loa infection may inhibit safe implementation of MDA.

• For schistosomiasis, changes in program targets require mapping at a finer scale to improve the precision of decisions to implement MDA.
