WHY YOU SHOULD WASH YOUR HANDS OFTEN

Nearly everything we touch is covered with germs. This includes bacteria, viruses, and parasites that can make us sick. You don't have to see dirt on an object for it to spread germs. If you touch something with germs on it, and then touch your own body the germs can spread to you. If you have germs on your hands and touch something or shake someone's hand, you can pass the germs on to the next person. Touching foods or drinks with unwashed hands can spread germs to the person who consumes them.

Washing your hands often during the day can help prevent the spread of a number of different illnesses. Here are a few examples:

There is a proper way to wash your hands that works best to get them fully clean. For cleaning your hands, all you need is soap and running water. Soap lifts dirt and germs from your skin, which is then washed away by the water.

Soap and water work the best, but if you don't have access to them, you can use hand sanitizer. Hand sanitizer works nearly as well as soap and water to kill germs.
