Scientists have figured out how far germs spread when coughing and sneezing.

Coronavirus, continuing to collect more and more victims around the world, respiratory infection. This means that it is transmitted from the patient to healthy when coughing or sneezing.. Scientists at the beginning of the last century identified safe distances at which you can be without fear of catching the infection from the virus carrier. Until now, these recommendations have been used by doctors..

However, as it turned out, it’s not one or two meters that are safe, but a much greater distance. American physicists from the Massachusetts Institute of Technology proved that an air cloud sneezes 7-8 meters from a source and viruses stay in the air much longer than previously thought.

To prove their case, they used a rapid camera, capable of doing 2000 frames per second. With its help, it was possible to fix the process of sneezing, then to evaluate the sedimentation rate of droplets of different sizes and measure the distance over which they fly.

It is also proven that when coughing, droplets of saliva with viruses scatter by about 2. 5 meters and can carry the risk of infection for up to several minutes, until they dry out and settle.

These data are very important for the fight against coronavirus.. The authors of the study give an example when patients were infected with coronavirus in Singapore hospitals, even when they could not find it in the air of rooms. It could well be that a virus in a cloud of particles from coughing or sneezing patients could get into the ventilation and spread through it. That is why surface disinfection and wet sanitation are so important..

Yes, and staying away from a coughing and sneezing person should be at a much greater distance than a meter or two previously prescribed. The virus carrier itself should think about others and cover its face with a scarf or mask..
