The virus is similar to Severe acute respiratory syndrome (Sars) and Middle Eastern respiratory syndrome (Mers). Meanwhile, a study conducted by the Northwestern Medicine health system on 509 COVID-19 patients in the Chicago area has concluded that almost a third of them suffered from altered mental functions, known as encephalopathy.
A group of experts in aerosolized particles and infectious diseases urged officials to incorporate more of the science on aerosolization into the public health response in a letter published Monday, saying that if symptomatic people are staying home, there should be more emphasis on protecting people from asymptomatic spread through indoor air with proper ventilation and moving events and gatherings outside whenever possible. However risk of transmission decreases with distance and passing time as the larger particles fall to the ground, and; "with passing time, the amount of infectious virus in respiratory droplets also decreases".
The main way coronavirus spreads is through larger droplets propelled through the air by the actions of an infected person.
In September, the CDC first updated its guideline, acknowledging that the coronavirus can spread through aerosols, but it was reverted a few days after.
The agency said its recommendations for avoiding the virus remain the same.
Now, the CDC's new update says that COVID-19 can sometimes be spread by airborne transmission.

It should be mentioned that a mesh face mask , for those not aware, is not appropriate Personal Protection Equipment. Del Rey later posted a video of herself reading poetry in a camo fabric mask .
"Some infections can be spread by exposure to the virus in small droplets and particles that can linger in the air for minutes to hours".
"Today's update acknowledges the existence of some published reports showing limited, uncommon circumstances where people with COVID-19 infected others who were more than six feet away or shortly after the COVID-19-positive person left an area", the CDC said. For example, the infected person might be breathing heavily after a workout session, and the droplets did not leave the place due to inadequate ventilation. Small droplets and particles spread apart in the air, CDC added. The people infected were in the same space at the same time as the infected person, or soon after the infected person had left.
As per the agency's website, you need to be six feet away - given that close contact still appears to be a more common way of transmission - as well as wear a mask, wash hands frequently, and clean surfaces regularly.
The CDC also said Monday that "increasing evidence" suggests "children and adolescents can efficiently transmit" COVID-19.
Poorly ventilated enclosed crowded spaces are are riskier than outdoors. People can protect themselves from COVID-19 by staying at least 6 feet away from each other.
