Water, sanitation and hygiene and neglected tropical diseases in the Democratic Republic of Congo: a narrative review and policy perspective

Abstract

Neglected tropical diseases (NTDs) remain a significant public health challenge in the Democratic Republic of Congo (DR Congo) due to its direct connection with the scarcity of clean water, poor sanitation facilities, and insufficient hygiene practices. Therefore, investigating comprehensive strategies to decrease NTDs by addressing Water, Sanitation, and Hygiene (WASH) issues is pertinent. This paper presents a narrative review of available literatures and policy briefs, and explains the aspect of WASH in NTD control with special reference to DR Congo. We review the country-specific barriers to the incorporation of WASH in NTD programs, such as conflict and governance issues, and limitations in infrastructure. In our synthesis, although WASH interventions have been established to effectively mitigate schistosomiasis, trachoma and soil-transmitted helminths at the global level, they are complicated by factors including insecurity in the eastern provinces of the DRC, poor health governance and inadequately funded water infrastructure. We also determine community-based innovations, and policy integration opportunities. Emphasizing WASH strategies in combating NTDs can lead to better health outcomes, less disease impact, and greater quality of life for affected communities.
