Community-directed distributors—The “foot soldiers” in the fight to control and eliminate neglected tropical diseases

The neglected tropical diseases (NTDs) affect hundreds of millions of people, predominantly in rural, often difficult-to-access areas, poorly served by national health services. Here, we review the contributions of 4.8 million community-directed distributors (CDDs) of medicines over 2 decades in 146,000 communities in 27 sub-Saharan African countries to control or eliminate onchocerciasis and lymphatic filariasis (LF). We examine their role in the control of other NTDs, malaria, HIV/AIDS interventions, immunisation campaigns, and support to overstretched health service personnel. We are of the opinion that CDDs as community selected, trained, and experienced “foot soldiers,” some of whom were involved in the Ebola outbreak responses at the community level in Liberia, if retrained, can assist community leaders and support health workers (HWs) in the ongoing Coronavirus Disease 2019 (COVID-19) crisis. The review highlights the improved treatment coverage where there are women CDDs, the benefits and lessons from the work of CDDs, their long-term engagement, and the challenges they face in healthcare delivery. It underscores the value of utilising the CDD model for strong community engagement and recommends the model, with some review, to hasten the achievement of the NTD 2030 goal and assist the health system cope with evolving epidemics and other challenges. We propose that, based on the unprecedented progress made in the control of NTDs directly linked to community engagement and contributions of CDDs “foot soldiers,” they deserve regional and global recognition. We also suggest that the World Health Organization (WHO) and other international stakeholders promote policy and guidance for countries to adapt this model for the elimination of NTDs and to strengthen national health services. This will enhance the accomplishment of some Sustainable Development Goals (SDGs) by 2030 in sub-Saharan Africa.Author summary: Community-directed distributors (CDDs), sometimes known as community health workers (CHWs), have proved to be critical in the delivery of medicines and other tools for the control of neglected tropical diseases (NTDs), prevention of malaria, and other beneficial health interventions. The distributors are the unsung heroes and heroines without whom the health of hundreds of thousands of communities in rural Africa would be worse than it is today. In this paper, we document more than 2 decades (1997–2019) of the contributions of 146,000 communities and 4.8 million CDDs of medicines for NTDs, unpaid or minimally compensated, some have provided 18 years of uninterrupted service. We report on the burden of work and their perspectives of the challenges involved in mass drug administration (MDA) across 27 countries in sub-Saharan Africa. We suggest that they have not been adequately recognised and that harnessing such community human resources could contribute to improving health system’s responses to the ongoing Coronavirus Disease 2019 (COVID-19) crisis. We recommend policy measures for a wider application of existing networks of CDDs by countries’ health systems to consolidate and accelerate the achievements made as well as for the attainment of the goals set forth in the newly developed World Health Organization (WHO) NTD Roadmap.
