The CDC handwashing technique involves the following steps:
Wet your hands with clean, running water and apply soap.
Lather your hands by rubbing them together with the soap, including the backs of the hands, between fingers, and under nails.
Rinse thoroughly from wrists to fingertips.
Dry hands with a clean towel or air blower.
If possible, use a towel to turn off the faucet and open the door when leaving a restroom.
Getting into the habit of consistent handwashing can protect you and others from a range of illnesses and is considered a key survival skill.
