Would you have ever said, exactly one year ago, that our life would have changed so radically
that we would all be forced to use masks and leave the house only for necessity or work
Like a war, there is an enemy invisible and of infinitesimal proportions that can affect each of us. We can’t see it, we can’t defeat it, but we can minimize the risk of it seriously hurting us. And, it seems, in closed environments the danger is always at the door. The reason
is explained to us by the most recent scientific studies. Covid danger indoors
Probably each of us feels safer when we are indoors, but it could be quite the opposite. Especially if we received friends and relatives shortly before in our house. According to most scientific reports, Covid spreads indoors through aerosols that remain infectious for a long time in the air we breathe and in objects that are touched inside a room. This means that if traces remain inside our house we could come into contact with them even when the person has already left our house. Period in which you are generally more vulnerable and without masks. Covid, social distancing is needed
According to a recent report by the American Centers of Disease Control and Prevention (CDC), the tiny droplets that are suspended in the air – which could contain infected viruses – can be spread over six feet away (about two meters). If we add to all this the fact that the virus could remain for a long time in the air we breathe in a closed environment, it goes without saying that the latter is considered more dangerous and at high risk of contagiosity. Distant yes, but for how long
Another study, coordinated by Suresh Dhaniyala – a professor at Clarkson University – highlighted how initially the danger of contracting the Coronavirus in an internal environment is limited to the people who are next to the infected person. The problem arises when, after some time, the virus begins to spread even to more distant areas. By potentially infecting anyone in that environment. To reach these conclusions, Dhaniyala injected aerosol particles similar in size to those of humans and monitored them thanks to dedicated sensors in a university classroom that housed – generally – 30 students. In just 15 minutes the particles made it all the way to the back of the room, although the concentration was slightly reduced in the back. However, the scientist suggests that the risk of contracting Covid, with adequate ventilation, is certainly greater in the areas closest to the infected person. The danger can increase if the room is not well ventilated because the virus remains longer in certain areas. On the other hand, if you are next to air vents you expose yourself to a greater risk because the particles suspended in the air are first sucked and then made to flow together in a rather small area of ​​the room. Being nearby therefore means exposing yourself to a very high risk of contracting the virus. if you and near air vents you expose yourself to a greater risk because the particles suspended in the air are first sucked and then made to flow together in a rather small area of ​​the room. Being nearby therefore means exposing yourself to a very high risk of contracting the virus. if you and near air vents you expose yourself to a greater risk because the particles suspended in the air are first sucked and then made to flow together in a rather small area of ​​the room.

yourself Always wear a mask when visiting friends or relatives. Do not touch objects that have touched other people, and if you do, disinfect your hands well. Always open the window if someone has entered your home. And remember: the greatest danger comes with asymptomatic people.
