This guidance note helps WASH staff in their preparedness and response to the current COVID-19 pandemic. It provides an overview of Infection Prevention and Control (IPC) and its intersection with water, sanitation and hygiene (WASH). It also provides key actions that staff can implement to help prevent infection and its spread in health-care facilities: from human to human, among health care workers and patients, through droplets, and by touching surfaces contaminated with the virus. WASH, including waste management and environmental cleaning, is essential for IPC.
