Coronavirus-COVID-19: Mask or not?

The virus spreads with saliva, so both with the droplets projected talking and breathing, both with the steam contained in the air that we exhale, and through the objects that are contaminated by these agents.

Coronavirus-COVID-19: Starnuto, how the virus spreads.

The surgical mask stops saliva droplets in both directions.
Saliva is also emitted when talking or breathing, not just when sneezing.
Droplets can reach up to four meters, but many settle within two meters.

The FFP3 mask also stops viruses contained in vapours.
If you feed on a cold glass you see the steam of your breath condensing.
This vapor can contain the virus and can go through a surgical mask, but not an FFP3 mask.
The virtus can survive in the steam for up to 30 minutes.

The gloves and hand washing are used to avoid contaminating the objects or contaminating their hands and then contaminating themselves by touching the face.

These are the recommendations in short, we invite you to read below the details and related documentation.

The mask should always be worn when passing or staying in indoor or outdoor areas where there are, or have been, other people who might be infected.
If you do not have the mathematical security that all the people present or transited before in the affected area were definitely healthy, you must wear all possible protections, compatible with the situation.
Not wearing a mask means exposing yourself to contagion and having a high probability of infecting people or infecting objects and animals that in turn could infect people.
Given the incubation period of the virus we can never be sure that we are not healthy carriers. We can never be sure that others are healthy. For this reason you should always wear the mask, except when you are at home with your cohabitants not quarantined.
Normally the surgical mask is fine as it stops most infections by blocking saliva droplets.
When possible and especially if it increases the likelihood of being infected or in environments with infected people, the FFP3 mask is strongly recommended, preferably without valve.

Consider that every time you go out a certain amount of virus enters inside your body,
so get out as little as possible and with the maximum protections,
so that your body can defend itself against the virus that attacks you,
and eliminate it completely before that you go out again.
