Hand washing:an essential barrier gesture against viruses

To fight against the Covid-19 coronavirus pandemic responsible for the confinement of several countries, properly carried out hand washing is essential. Soap or hydro-alcoholic gel, practicing this barrier gesture has become a civic gesture.

Transmission of viruses by hands

Some viral diseases are transmitted mainly by the hands:we speak of hand-borne transmission . It is enough to rub your eyes, nose or put your fingers in your mouth to be sick. We touch our face about 3000 times a day on average so to protect ourselves from contagion, hand washing is an effective and essential barrier gesture.

How do viruses get on hands?

Flu, colds, bronchitis, gastroenteritis and Covid-19 disease (new coronavirus) are transmitted by secretions from the sinuses and larynx, but also by direct contact of the hands with infected people. To be contaminated, it suffices to shake the hand of a patient, to be less than a meter from him by exposing himself to his infected droplets, or to touch a contaminated object:a door handle, a mobile phone , a shopping cart, an elevator button, a bus bar….

Some viruses can survive for a long time in the open air. The Influenza virus, responsible for the flu, and the gastroenteritis viruses can live for several days on inert surfaces.

A recent study published in the New England Journal Of Medicine and relayed on March 17 by the National Institutes of Health (NIH) compares the new coronavirus Covid-19 (or SARS-CoV-2) to the virus responsible for SARS in 2003 called SARS- CoV-1. Although the Covid-19 virus is a fragile virus in outdoor conditions, it would be detectable for 3 hours in aerosolized form and several days on certain surfaces such as plastic or stainless steel depending on the temperature, the humidity level and the quantity of virus present at the start.

The anti-coronavirus barrier gesture:hand washing

In addition to viruses, bacteria and fungi are also infectious agents that can be transmitted by the hands. Wash your hands scrupulously protects against many infections, and avoids infecting loved ones, especially in times of confinement .

The Directorate General for Health (DGS) and the Regional Health Agencies (ARS) regularly renew their recommendations:frequent hand washing, with soap and water, or with a disinfectant solution (hydro-alcoholic solution) is the essential gesture to stop epidemics.

How to wash your hands properly?

A simple rinsing with water before drying your hands on a damp cloth will not help much. You can learn to wash your hands effectively!

To kill germs , you can use soap and water or disinfectant gel. Handwashing with soap and water should take at least 40-60 seconds according to the recommendations, and is broken down into 3 stages. You will need to rub effectively in all corners before rinsing with water and drying.

  • Rub your hands , palm to palm, then palm of one hand to back of the other hand. Continue with interlaced fingers to reach all corners. Rub your fingers against the palm of the other hand, before insisting on the thumbs. Do not forget the underside of the nails which accumulates germs. Finally go up to the wrists to lather them vigorously.
  • Second step:rinsing . Allow 10 seconds for this phase by running the water from the fingertips to the wrists.
  • Proceed to drying . Cloth towels are vectors of contamination:they are reusable and create a humid and warm environment conducive to the development of microbes. Ideally, you should dry your hands with a single-use paper towel. Preferably, turn off the tap with this towel before throwing it away.

Hand washing with a disinfectant solution must last 30 seconds and requires no rinsing.
