Handwashing can keep us healthy and prevent the spread of respiratory and diarrheal infections from one person to another. In fact, COVID-19 can spread from person to person or from surfaces when someone:

• He touches his eyes, nose, and mouth with unwashed hands.
• Prepare or consume food or drinks with unwashed hands.
• Touch a contaminated surface or object.
• Blows his nose or covers his nose and mouth with his hands when he coughs or sneezes and then touches another person's hands or touches common objects.

Earlier we talked about the hand washing where we list the key moments to carry out the cleaning of the hands but, on this occasion, we will list the 5 steps to comply with a correct disinfection that can be carried out at home, in the workplace, at school, in hospitals or in any other community.

• wet your hands with clean running water (warm or cold), turn off the tap.
• soap up your hands and start to foam.
• rub for at least 30 seconds your hands, the foam should cover the back of the hands, between the fingers and under the nails.
• rinse thoroughly your hands under clean running water.
• dry with a paper towel your hands and with the same one close the tap.

If you don't have access to soap and water, the CDC recommends using hand sanitizer that contains at least 60 % alcohol. The way to know if the sanitizer contains at least 60 % of alcohol is by reading the product label. Rub the gel over all surfaces of your hands and fingers until they are dry. This should take about 20 seconds.
