As our dear authorities are unable to provide masks to the population, let's be smart and resourceful !!
I therefore anticipated the opinion of this researcher at the CNRS

Philippe Dumas, research director emeritus at the CNRS in Strasbourg, launched a call for the manufacture of handmade masks in order to compensate for the lack of "official" masks for the general public.
"It is absolutely necessary to reduce the speed of spread of the virus," he explains. The doubling rate is currently 3 days. If we can get it to 6 days, it's considerable! " For him, this goal can only be achieved if the entire population has access to masks. However, industrially manufactured masks are reserved primarily for nursing staff and professionals in contact with the most fragile people.
Hence the idea of making your own masks out of fabric, washable and reusable. An activity which could also have the advantage of occupying the hands during confinement. "These masks are not perfect," admits the researcher. However, they should not be disparaged as some people do. Because they can help, provided you change them every two or three hours and wash them, to slow down the epidemic by providing protection. "
Philippe Dumas also pleads for people to be forced to wash their hands when entering super and hypermarkets. “Either with the alcoholic solution, or with water and soap. It is quite possible for large surfaces to organize this. It's little things like that that can decrease the speed of spread of the virus. ”
Manufacturing explanations and a pattern are available on this site. But Philippe Dumas made a simpler version of it by making a fabric mask with a pocket in front of the nose and mouth, in which he places several layers of handkerchiefs or paper towels that can be changed very easily. “You just have to make sure that the mask fits properly around the nose and mouth.
