The Impact of WASH on Re-infection with STH
Soil-transmitted helminths (STH) refer to a group of parasites that live in the human digestive system. These parasites include roundworm, whipworm, and hookworm. The parasites live in the soil in warm and humid climates and are spread through contact with feces of infected people. Worldwide, approximately 1 billion people are infected with STH or at risk of infection
This grant allows the investigators to add STH outcomes to an NIH-funded cluster randomized trial that randomizes a group of communities in Ethiopia to either a water, sanitation, and hygiene (WASH) intervention at the beginning of the study (WASH intervention group) or at the end of the study (comparison group).
