Frequent and proper handwashing with soap is one of the most important measures that can be used to prevent the spread of diseases and infections, such as the coronavirus. Yet recent statistics demonstrate that 40 percent of households lack access to a handwashing facility with soap and water. And 18 percent of those households have nowhere to wash their hands.
These statistics translate into billions of households without the basic essentials to fight the coronavirus—soap and a sufficient water supply. USAID and the Global Handwashing Partnership (GHP) continue their collaboration to raise awareness about the persistent inequalities in access to water, sanitation, and hygiene (WASH) and work to ensure that lifesaving supplies of soap and water will be available to those in need to prevent new infections now and provide a foundation for economic recovery later.
We would like to thank GHP for its collaboration on this issue of Water Currents, which contains peer-reviewed studies and reports on handwashing that were published from January through June 2020.
