An estimated 1 billion people in the world live without access to any type of sanitation facility, such as a toilet or latrine. Sanitation access is known to be associated with the risk of transmitting certain diseases, including parasitic worms. But the impacts don’t stop there. For children, living in a community with poor levels of sanitation access increases their odds of stunted growth, anemia, and diarrhea, even if their household has access to a sanitation facility.
