A recent study on COVID-19, conducted by Korean scientists from the Jeonbuk National University School of Medicine, found that airborne transmission of the virus occurs even after just 5 minutes more than 6 meters from a positive. And it has also been found that walking through narrow corridors increases the risk of contagion if there is a positive who has sneezed or coughed in front of him, even at a distance greater than the “safe” distance. At risk in this case I am especially children.
The latest discovery was made by a research team from the State Key Laboratory for Nonlinear Mechanics of the Chinese Academy of Sciences and the College of Engineering Sciences of the Academy University. “For him separate mode, the droplet concentration is much higher than in adjoint mode, five seconds after a cough”Said one of the experts who supervised the investigation. “These results represent a great challenge to determine a safe social distance in places like very narrow corridors, where a person can inhale viral droplets even if the positive is way ahead of us “added the expert. The scientists discovered that after a launch a launchand the clouds full of viral particles make they disperse in two different ways and it can increase the risk of contagion. In the first case, the particles remain attached to the body of the person, who carries them with him like a backpack; in the second they leave creating one floating bubble, where the above are much more concentrated compared to the first variant.
