There are still many mysteries surrounding the virus of the Covid-19 and its baud rate. Distance, for example, has already been seen as a effectively to combat contamination. However, a study at Cambridge University in the United Kingdom shows that this alone is not enough.

The study published in the scientific journal Physics of Fluids indicates that airborne transmission may exceed the two meter barrier. Of course, the greater the distance, the lower the chances of contamination. However, the use of masks is essential.

“I thought to myself, if that were the case, the virus should leave an infected person and land on the surface or disperse into the air through fluid mechanical processes,” said Epaminondas Mastorakos, a professor in the Cambridge Department of Engineering and research leader .

Distancing against Covid-19

The result indicates that distancing alone is ineffective to avoid contamination by Covid-19. The conclusion is that an unmasked person who coughs can make the particles reach two meters away.

Scientists ran simulations to see how many droplets hit a person at a certain distance. There was no very sudden change in the particles' path at a distance of two meters. 

Although large samples can hardly overcome this barrier, smaller samples can go beyond this. “Small droplets can be suspended in the air for a long time and can transport pathogens significantly long distances, while larger droplets follow a ballistic trajectory and tend to settle quickly under the influence of gravity,” says the study.
