Inhalation contagion: When a person sneezes or coughs, it emits droplets that may contain the virus. If these droplets are breathed in by someone else, it will spread. The health authorities (from the WHO, to those of our country) have confirmed that these droplets do not exceed in any case more than 1 meter and a half, therefore, the contagion by this mechanism can only be avoided with the distancing. You don't need a respiratory protection mask if you can distance yourself. In fact, doctors recommend not wearing a mask, because it creates a false sense of security, and people do not worry about keeping their distance, therefore being more exposed to contagion. It should also be borne in mind that most masks are not useful to avoid contagions (surgical, clothing, and simple powder called FFP1 are not useful for healthy people, they should only be worn by infected people). The effective ones are FFP2 and FFP3.

Contact contagion: A person who is infected can leave the virus on the surface (tables, door knobs, furniture, etc.) with the droplets of his cough, or with his hands when he has first touched his nose and then touches these objects. The COVID-19 virus can survive on these surfaces for a few hours. If during this period of time, another person touches these objects with their hands, the virus will be in their hands, and when this person touches their nose or mouth or eyes, the virus will be transmitted from their hand to their nose. , and through this route you will directly access the interior of the body, infecting it.
In no case the virus can penetrate the skin of the hand, if there is no open wound. Therefore, having gloves does not change the contagion system, because if the person wears gloves and touches the object that contains the virus, the virus will pass from the object to the glove, and from the glove to the person's nose or mouth, when this is touched. For this reason, it is necessary to wash your hands continuously (with or without gloves), especially when you have just touched objects that may have been touched by other people, and gloves will only be useful when we immediately change them every time we touch an object. possibly contaminated.
