Handwashing is an important aspect of good hygiene and a critical way to reduce the spread of sickness, including coronaviruses. Proper handwashing includes using soap and water for at least 20 seconds and rubbing all parts of the hands, including between the fingers and under the nails. Washing hands often, especially after coming in contact with other people or being in public, is one of the most effective ways to reduce the spread of viruses. Handwashing can also help reduce other forms of sickness, such as colds and flu. To ensure the most effective handwashing technique, the World Health Organization recommends the following steps: 1. Wet hands with warm running water. 2. Apply ample soap. Lather the soap by rubbing hands between palms. 3. Rub hands together for at least 20 seconds, making sure to cover each part of the hands, including the nails and the area between fingers. 4. Rinse hands under warm, running water. 5. Dry hands thoroughly with a clean towel, paper towel, or air dryer. 6. Use alcohol-based hand sanitizer if soap and water are not available. Good handwashing is the best way to protect yourself and others from the spread of viruses and other illnesses. It is important to remember to wash your hands often, especially when coming in contact with other people or being in public.
