Keeping hands clean is one of the most important steps we can take to avoid getting sick and spreading germs to others.

Many diseases and conditions are spread by not washing hands with soap and clean, running water. If soap and water are unavailable, use an alcohol-based hand sanitizer that contains at least 60 percent alcohol to clean hands. Here's a refresher:

• Wet your hands with clean, running water and apply soap. Use warm water if it is available.
  
• Rub hands together to make lather and scrub all surfaces.
  
• Continue rubbing hands for 20 seconds. Need a timer? Hum the "Happy Birthday" song from beginning to end twice.
  
• Rinse your hands well under running water.
  
• Dry your hands using a paper towel or air dryer.
  
• If possible, use your paper towel to turn off the faucet.
