Hand washing is by far the best way to prevent germs from spreading and to keep you from getting sick. Good hand washing is the first line of defense against the spread of many illnesses, from the common cold to more serious illnesses such as meningitis, and influenza. http://kidshealth.org/parent/general/sick/hand_washing.html
Let’s scrub those germs away. To get started you will need water, liquid or bar soap, and a drying material such as paper towel or hand towel.
Turn on the water. Make sure the water isn't too hot. You should use warm water so that you do not burn or scald your skin.
Thoroughly wet your hands and wrist.
Get your soap. Antibacterial soap isn't necessary — any soap will do.
Now that you have your soap, lather your hands and wrist for about 10 to 15 seconds. You can also sing the happy birthday song to make sure you have lathered and scrubbed long enough. Remember to scrub between the fingers and under your nails where germs are plentiful and don’t forget your wrist.
Rinse your hands completely. Make sure that all soap is gone from your fingers, finger nails, and wrist.
Dry hands and wrist completely using a paper towel or a clean hand towel.
Turn off the water using your paper towel or a hand towel. Remember when you first turned the water on your hands were dirty. To prevent recontamination do to not touch the faucet again with your bare hands.
To help prevent the spreading of germs always remember to wash your hands * before eating and cooking * after using the bathroom * after touching animals, including classroom and family pets * after blowing your nose, coughing, or sneezing * and after being outside
