The research highlights the critical importance of sanitation in improving public health and alleviating poverty in Bangladesh. Low sanitation coverage, with only 33% of households having access to hygienic latrines, contributes to high disease burden and healthcare costs. Diarrheal diseases are a major issue, causing child mortality and impeding economic development. Improved sanitation interventions have shown significant positive impacts, reducing diseases and medical costs, increasing productivity, and empowering women. The government aims to achieve 100% sanitation coverage by 2010 through targeted strategies and collaboration with various stakeholders. The research underscores the need for holistic sanitation efforts to break the cycle of disease transmission and enhance overall well-being
