Handwashing is more than just running water over your hands. Washing your hands with soap and water is one of the best ways to prevent the spread of infections. It helps prevent diseases, such as colds, influenza (flu), and foodborne illness. It's easy. It doesn't cost much. And it works.
Wash your hands:
- Often, especially during cold and influenza (flu) season. This can reduce your risk of catching or spreading a cold or influenza.
- Before, during, and after you prepare food. This reduces your risk of catching or spreading bacteria that cause a foodborne illness. Be especially careful to wash before and after you prepare poultry, raw eggs, meat, or seafood.
- Before and after you care for someone who is sick. It's also important to wash your hands before and after you treat a cut or wound.
- Before you eat.
Wash your hands after you:
- Go to the bathroom or change diapers. This reduces your risk of catching or spreading diseases such as salmonella or hepatitis A.
- Cough, sneeze, or blow your nose.
- Handle or prepare foods, especially after you touch raw meat, poultry, fish, shellfish, or eggs.
- Touch an animal, animal waste, pet food, or pet treats.
- Handle garbage, use the phone, or shake hands.
Public health experts recommend the following steps for handwashing:
If soap and water aren't available, use a hand sanitizer or alcohol-based hand wipe that contains at least 60% ethyl alcohol or isopropanol. Carry one or both with you when you travel, and keep them in your car or purse. These products can help reduce the number of germs on your hands. But they don't get rid of all types of germs.
If you use sanitizer, rub your hands and fingers until they are dry. You don't need to use water. The alcohol quickly kills many types of germs on your hands.
