Clean water, sanitation, and hygiene (WASH) access is a foundation of public health. This Public Health World Conference (PHWC)session will explore international initiatives to enhance sanitation facilities and hygiene habits in low-resource environments. Experts will present new water purification technologies and waste management techniques. Case studies will also demonstrate the effectiveness of WASH interventions in preventing childhood mortality and infectious disease prevalence. The session will examine the influence of international assistance and policy change on achieving universal access to safe water. Participants will learn about community-based sanitation programs and how they are sustainable in the long term.
