Corona virus Is Too Dangerous Only 8 Meters Is Safe!

As the new coronavirus spreads worldwide, more and more scientists are beginning to study this terrible infectious and contagious seemingly unprecedented plague killer, looking for ways to get rid of demons, or at least avoid them. Recently, Professor Lydia Brubar from the Massachusetts Institute of Technology discovered that virus particles ejected when humans cough and sneeze can spread at a speed of 10-30 meters/second in the warm and humid air. The infectious "turbulent clouds" formed can reach places more than seven or eight meters away-this means that the so-called safe social distance of 2 meters, which is widely known and widely observed, is simply not safe at all. It is terrible.

Professor Brupa took a video of a healthy person exhaling and sneezing violently and then slowed down his speed to conduct research and discovered this terrible phenomenon. If a potentially infected person in front of you, once he coughs or sneezes, he may spray the virus into the air within 8 meters and suspend it there. The humid and warm air can also make the virus droplet stay there more. For a long time, you have almost nowhere to escape!. This is only based on distance estimation and does not take into account that the flowing air will spread the virus particles to a larger range and farther away. According to another study published recently, when these droplets fall, they can also contaminate railings, handrails, furniture surfaces and even food. Depending on the temperature and material, the virus can survive for hours to days or even a month. Even if the droplets evaporate, these viral particles may be trapped in indoor ventilation and air-conditioning systems in supermarkets, hospitals, and so on.
