Hand-washing is the basic tool for the fight against Covid-19. It has been shown that an adequate handwashing technique removes the virus from our skin, which significantly reduces the rate of infections. However, a bad washing technique can mean that we can infect more people or ourselves.

It has been shown that the use of alcohol gel with concentrations greater than 70% is similar to the use of soap and water. The advantage of alcohol is that it can be carried in your pocket in more portable containers.

The technique for hand washing is as follows:

1. Apply enough water and soap in the hand to distribute it evenly to the wrist, or failing that enough alcohol gel to cover evenly to the wrist.

2. Rub the palms of your hands to each other. In the case of soap, favor the formation of foam.

3. Rub with the palm of one hand and the back of the hand on the opposite side interlacing your fingers. Perform the same procedure with the opposite hand.

4. Rub both palms intertwining your fingers.

5. Rub the back of your fingers with the palm of your hand on the opposite side, placing your hands in the shape of a "C", grabbing your fingers.

6. Take your thumb by catching it with your hand on the opposite side, and rub it with circular movements. Perform the same action with the opposite hand.

7. Rub the tips of the fingers of one hand with the palm on the opposite side with circular movements. Perform the same action with the opposite hand.

8. Take a doll by catching it with the palm of your hand on the opposite side and rub it in circular movements. Perform the same action with the opposite hand.
