Social Distancing: What distance to protect you infected Coronavirus

Lydia Buruiba, Ph.D. from MIT, investigated how far the particles of fluid spread when we sneeze. After analyzing the results, she published a scientific article. According to which it turns out that protecting yourself from COVID-19 is more difficult than we used to think.

Tests have shown that the rate of fluid propagation at the peak of expiration can reach 30 meters per second. As a result, a cloud of small droplets is formed, spreading up to 7–8 meters. If a person is infected, these droplets may contain SARS-CoV-2 pathogens and infect a healthy person who is nearby.

Keeping a distance: at what distance will you not get infected if someone sneezes nearby

At the same time, WHO is now recommending a distance of 1 meter, and the US Centers for Disease Control and Prevention are  talking about 6 feet, or about 2 meters. A new study showed that only 7-8 meters would be a safe distance.

Such a distance is difficult to keep in confined spaces, for example, in a store, at the post office or even just in the staircase (especially if you need to use the elevator). That is why you should listen to the recommendations of the authorities and stay at home. If possible, food should be bought immediately for a long time – or use delivery .
