Hand-washing is a simple and effective way to help prevent diseases, such as colds, flu, and food poisoning.
When to wash your hands
Wash your hands after:
The U.S. Centers for Disease Control and Prevention recommend the following steps for hand-washing:
If soap and water are not available, use gel hand sanitizers or alcohol-based hand wipes containing 60% to 90% ethyl alcohol or isopropanol. Most supermarkets and drugstores carry these products. Carry one or both with you when you travel, and keep them in your car or purse.
If using the gel sanitizer, rub your hands until the gel is dry. You don't need to use water. The alcohol in the gel kills the germs on your hands.
