Water, sanitation, and hygiene (WASH) services that are safely managed are important to preventing and preserving human health during infectious disease outbreaks, such as the current COVID-19 pandemic. Investing in critical public health infrastructure, such as water and sanitation systems, is one of the most cost-effective methods to enhance pandemic preparedness, especially in resource-constrained areas. Regularly executed WASH and waste management procedures act as barriers to human-to-human transmission of the COVID-19 virus in families, communities, health care facilities, schools, and other public places.
