According to the Centers for Disease Control and Prevention (CDC), handwashing can prevent one in three cases of diarrhea and one in five respiratory infections, such as a cold or the flu. To improve community hand hygiene, the CDC Foundation collaborated with CDC’s Waterborne Disease Prevention Branch to develop a new suite of handwashing materials that encourage adults to make handwashing and hand sanitizing a healthy habit, with special emphasis on parents and caregivers, people cooking at home, and people using public restrooms.
