Answer:
Washing your hands is one of the most important things you can do to avoid getting sick and spreading germs to people around you.
The best way to prevent the spread of infections and decrease the risk of getting sick is by washing your hands with plain soap and water, advises the Centers for Disease Control and Prevention (CDC). If soap and water are not available, the CDC recommends using an alcohol-based hand sanitizer that contains at least 60 percent alcohol to reduce the number of germs on your hands. However, hand sanitizers do not eliminate all types of germs, are not as effective when hands are visibly dirty or greasy, and may not remove harmful chemicals.
Hand sanitizers are an easy, quick alternative when handwashing with plain soap and water isn’t convenient or possible. Hand sanitizers often have a form of alcohol, such as ethyl alcohol, as an active ingredient and are used as an antiseptic.
