In the latest evaluation, the American Centers confirm that the virus can be transmitted through large droplets or small particles when a person coughs or sneezes, speaks and breathes.
Although the virus can be transmitted through the air, this method is not the main cause of the spread of the infection, according to the American academic who specializes in the spread of viruses, Linzi Marr.

According to the “New York Times” newspaper, US centers had underestimated these risks, in a position they expressed just two weeks ago.
New estimates warn that the virus that causes “Covid 19” can travel in the air within an enclosed space at a distance of up to 6 feet, or about 1.8 meters.
And the American Centers stated that this type of contagion with the Coronavirus was registered inside closed places that do not have adequate ventilation.
He added that in some cases, “the person with corona infection was breathing heavily (ie, closer to panting), as happens when a person is singing or exercising.
Due to this inconsistency in scientific opinions on the method of transmission, the US centers did not recommend the use of a protective mask until last April, that is, many months after the start of the epidemic.
As for the World Health Organization, it was recommended to use the muzzle last June, after the epidemic spread widely around the world.
Initially it was believed that the Corona virus was transmitted only through contact with surfaces contaminated with the virus, the handshake and the approach, so the gloves became preventive tools during the spread of Corona.
Last July, 239 researchers and experts urged the World Health Organization to recognize that the Corona virus is also transmitted through the air.
In the latest evaluation, the American Centers confirm that the virus can be transmitted through large droplets or small particles when a person coughs or sneezes, speaks and breathes.
Although the virus can be transmitted through the air, this method is not the main cause of the spread of the infection, according to the American academic who specializes in the spread of viruses, Linzi Marr.
