Proper hand washing is a simple yet effective way to help prevent the spread of illness. It's especially important to wash your hands frequently during cold and flu season, or during times when you are in close contact with others, such as at school or work. Follow these five simple steps to ensure that you are washing your hands correctly:

1. Wet your hands with clean, running water, and apply soap.
2. Rub your hands together to create a lather and scrub all surfaces, including the backs of your hands, between your fingers, and under your nails.
3. Continue scrubbing for at least 20 seconds. Need a timer? Hum the "Happy Birthday" song from beginning to end twice.
4. Rinse your hands well under clean, running water.
5. Dry your hands using a clean towel or air dry them.

It's important to wash your hands with soap and water whenever possible, but if those aren't available, an alcohol-based hand sanitizer can be an effective alternative. Be sure to use a hand sanitizer that contains at least 60% alcohol.

Remember, proper hand washing is an easy way to help protect yourself and others from getting sick. Make it a habit to wash your hands frequently throughout the day, and encourage others to do the same.
