It turns out that not all popular coronavirus protection methods work really well. However, VTT researchers have found that there is one highly effective way to avoid infection. About this – in the material of the publication Yle.
According to experts at the VTT Research Center, airing the premises will reduce the likelihood of infection with COVID-19. At the same time, the risk can easily be reduced by 90 percent. After airing, the room becomes safe for two hours. But in a poorly ventilated room, in just a few minutes, a person can catch a coronavirus.
According to the scientist Aku Karvinen, in the process of breathing, singing or talking, a person leaves small particles in the air. Moreover, the smallest of them disappear only after aeration or air exchange. The most dangerous thing is that such particles are able to stay in the air for several minutes or hours. In addition to airing, you can get rid of viruses with ventilation.
But social distance is not as effective as it seemed before. The fact is that, for example, in shopping centers there may be certain premises with a dangerous level of viral particles. Therefore, experts recommend wearing masks with protection classes FFP2 and FFP3 in public places. The problem is that a dangerous cloud with a virus can be several meters wide and long. In other words, it can be more than 1.5-2 meters, which is spoken about while maintaining social distance.
