“In closed spaces and with a reduced safety distance, the effectively protective masks are the Ffp2. In the metro, buses and public transport are the best choice”. Walter Ricciardi, professor of Hygiene at the Catholic University of Rome and consultant to the Minister of Health, explains this to Adnkronos Health, commenting on the debate on masks in France, where the Minister of Health has advised against the use of self-produced cloth masks and has invited to use those with greater filtering capacity in public.
“The masks as a garrison – explained Ricciardi – must always be worn according to the objectives that are proposed. If I am alone on the street, at a distance from others, the cloth mask is also fine. But if I enter in a closed environment. and I lower the safety distance, to be protected I need a mask type Ffp2. The scientific evidence tells us this: in a closed environment there is a need to have filtering masks. And the filtering ones are the Fp2 “.
The cloth masks, on the other hand, “only serve to keep the droplets of saliva from coming out of the mouth and nose of the people who wear them. They have no protective value for the wearer. So much so that the health personnel are also infected with surgical masks. All the more reason, therefore, it is possible to contagion with cloth masks. Obviously – he specifies – these are important devices in terms of virus circulation, precisely because they do not release droplets. But they are not a barrier to the virus. They are not protective towards the wearer, they are protective towards those who are close to the wearer “, concludes Ricciardi. (Adnkronos Health)
