Community-based ivermectin distributors: onchocerciasis control at the village level in Plateau State, Nigeria.

The use of community residents as agents for distributing mass ivermectin therapy for onchocerciasis provides a component of community participation absent from mobile team delivery methods. Community-based distribution, however, presupposes preexisting human resources in the endemic villages capable of fulfilling the essential functions of an ivermectin distribution process: mobilizing and educating the population, dispensing the drug, maintaining records, and monitoring and treating adverse reactions. Even when such human resources exist, the community workers must continue to receive tangible support from both external (government and donor agencies) and internal (community) sources. Donor and government agencies must accept that their data collection demands will be limited by the literacy standards of the communities being served. Community leaders must agree to set and use their own local standards of payment (including food stuffs or exchange in kind) to compensate the distributors for their time and efforts. The use of locally available human and remunerative resources is a prerequisite for true community ownership of a program.
