What does the Oms say Today about the use of the half masks?

Till now the Oms has maintained the "false sense of certainty" I date from putting the half mask on.
The last studies on the broadcasting of the virus have led the oms to see a little the positions again and to invite the population to put the half mask on to bound the diffusion of the coronavirus even if at sun they are not enough.
Then not only who he is is sliced by me or the one who assists infected persons, the half mask is carried in public places where it will be difficult to maintain the distance of certainty as transport, businesses and closed and crowded environments
The appeal is turned also to the one who assists the over 60 and persons with previous sicknesses, all others will have to put at least the half mask on in cloth to 3 layers
