Soil-transmitted helminthiasis (STH) is among the most common infection globally, primarily affecting the world’s poorest and most deprived communities. Over 24 million SAC are at-risk for STH in the 11 countries in Act | West’s portfolio. Caused by three categories of parasitic worms—hookworms, whipworms and roundworms—STH spreads when people inadvertently ingest contaminated food or water or walk barefoot on contaminated soil. Contamination occurs when worm eggs are passed into the soil or water via the feces of an infected person. STH can cause pain and diarrhea, fatigue, weakness malnutrition, impaired growth and development in children, and even intestinal obstruction and death.
