In 2020, the COVID-19 pandemic shocked health systems, demanding the urgent identification and prioritization of immediate health care facility needs. Beginning in August 2020, USAID’s MOMENTUM Country and Global Leadership provided rapid technical and capacity development assistance to local health networks in Bangladesh and four other countries to improve facility readiness in water sanitation and hygiene (WASH) and infection prevention and control (IPC). This package of materials details the impact and outcomes of this work, as well as lessons learned to inform future WASH and IPC efforts in health care facilities and quality improvement programming.
