What about the reasons for wearing a mask in all circumstances? Does is mean that it only takes for a person to come near someone else closer than 1m to have the virus spread? Even without touching or talking to him?

  1. The routes of infection are the hands and the air droplets that you share through breathing and speaking.

If you are not able to keep your distance (supermarket, bakery, …), it is useful to wear a mask outside of your house.
