Sanitation prevents soil transmitted helminth infections

Sanitation is a primary prevention strategy for soil-transmitted helminthiases. It prevents faecal pathogens such as intestinal worm eggs from contaminating the environment and infecting people through contaminated food, water, dirty hands and direct skin contact with the soil. Soil-transmitted helminthiases currently affect hundreds of millions of children worldwide, leading to undernutrition, anaemia and poor school performance.
