Good hand hygiene is one of the most reliable ways to not get sick. Wash your hands with soap and warm water for at least 20 seconds, especially after coughing, sneezing or touching surfaces in public. If soap and water aren’t available, use an alcohol-based hand sanitizer with at least 60% alcohol. Hand sanitizer isn’t a replacement for washing your hands. Use hand sanitizer when it’s all that’s available, but remember to wash your hands as soon as possible afterward.
