The purpose of handwashing is to remove germs from the hands so that germs are not transferred to the eyes, nose, and mouth to cause illness. To do a good job, first wet your hands. Next, apply plain soap. Rub your hands together for 20 seconds or the time it takes to sing Happy Birthday. Rinse for 10 seconds. Finally, dry with a clean, disposable towel.
It is important to wash your hands:
• after using the toilet
• before eating or preparing food
• after blowing your nose or helping a child with a runny nose
• after being with someone who is sick
• after handling shared objects (money, for example)
• before inserting/removing contact lenses
• before flossing your teeth
If you aren’t near a sink, use an alcohol-based hand rub. However, these products don’t kill all germs so they aren’t a substitute for handwashing. Wash hands with plain soap and water as soon as you can.
