Clean Hands

Washing your hands the right way can stop the spread of illness-causing bacteria.

Here’s how to do it:

  • Wet your hands with warm water and apply soap.
  • Rub your hands together and scrub them well. Make sure to scrub the backs of your hands and between your fingers.
  • Rub your hands for at least 20 seconds. Sing the Happy Birthday song if you need a timer.
  • Rinse your hands well under running water.
  • With the water still running, dry your hands using a clean towel and use the towel to turn the faucet off.
