Tailoring water, sanitation and hygiene (WASH) targets for soil-transmitted helminthiasis and schistosomiasis control


The World Health Organization’s (WHO) 2015–2020 global strategy on water, sanitation and hygiene (WASH) and neglected tropical diseases (NTD) encourages integration, while maintaining existing structured NTD investments, and acceleration towards Sustainable Development Goal (SDG) targets. Accordingly, SDG-associated and WASH–NTD indicators have been developed, commencing important intersectoral dialogue, alongside opportunities for future disease-specific refinements. The rationale for soil-transmitted helminthiasis (STH) and schistosomiasis-specific WASH considerations, and a traffic-light figure, are presented here to indicate where current international definitions may, or may not, suffice. Certain unique aspects in control dynamics and parasitic lifecycles, however, necessitate additional implementation research with more appropriate measurement indicators developed to record programmatic interventions and to define strategic priorities more effectively.
