Wash Your Hands

Washing handsHandwashing is one of the best ways to protect yourself and your family from getting sick.

Washing your hands is easy, and it's one of the most effective ways to prevent the spread of germs. Clean hands can stop germs from spreading from one person to another and throughout an entire community—from your home and workplace to childcare facilities and hospitals.

When should you wash your hands?

You can help yourself and others stay healthy by washing your hands often, especially during these key times when germs are likely to get on your hands and can easily spread to others:

Scrub your hands for at least 20 seconds.

  • Before, during, and after preparing food
  • Before eating food
  • Before and after caring for someone who is sick
  • Before and after treating a cut or wound
  • After using the toilet
  • After changing diapers or cleaning up a child who has used the toilet

What should you do if you don't have soap and clean, running water?

Washing hands with soap and water is the best way to get rid of germs in most situations. If soap and water are not available, use an alcohol-based hand sanitizer [423 KB] that contains at least 60% alcohol. You can tell if the sanitizer contains at least 60% alcohol by looking at the product label. Alcohol-based hand sanitizers can quickly reduce the number of germs on hands in some situations, but sanitizers do NOT get rid of all types of germs.

Hand sanitizers may not be as effective when hands are visibly dirty or greasy. Furthermore, hand sanitizers might not remove harmful chemicals like pesticides and heavy metals from hands. Be cautious when using hand sanitizers around children; swallowing alcohol-based hand sanitizers can cause alcohol poisoning if a person swallows more than a couple mouthfuls.

How do you use hand sanitizers?

  • Apply the gel to the palm of one hand (read the label to learn the correct amount).
  • Rub your hands together.
  • Rub the gel over all surfaces of your hands and fingers until your hands are dry.
