Water, Sanitation, Hygiene

According to the Centers for Disease Control, global access to safe water, adequate sanitation, and proper hygiene education can reduce illness and death from disease, leading to improved health, poverty reduction, and socio-economic development. However, many countries are challenged to provide these basic necessities to their populations, leaving people at risk for water, sanitation, and hygiene (WASH)-related diseases. Resources available within this theme offer information on providing access to safe water and appropriate sanitation facilities, and introducing sound hygiene behaviors.
