It is NOT just the larger droplets, but now WHO says possible it is the aerosol that is the the problem.
WHO: Indoor airborne spread of coronavirus possible

LONDON (AP) The World Health Organization is acknowledging the possibility that COVID-19 might be spread in the air under certain conditions after more than 200 scientists urged the agency to do so.
In an open letter published this week in a journal, two scientists from Australia and the U.S. wrote that studies have shown beyond any reasonable doubt that viruses are released during exhalation, talking and coughing in microdroplets small enough to remain aloft in the air.
The researchers, along with more than 200 others, appealed for national and international authorities, including WHO, to adopt more stringent protective measures.
WHO has long dismissed the possibility that the coronavirus is spread in the air except for certain risky medical procedures, such as when patients are first put on breathing machines.
In a change to its previous thinking, WHO noted on Thursday that studies evaluating COVID-19 outbreaks in restaurants, choir practices and fitness classes suggested the virus might have been spread in the air.
Airborne spread particularly in specific indoor locations, such as crowded and inadequately ventilated spaces over a prolonged period of time with infected persons cannot be ruled out, WHO said.
Still, officials also pointed out that other modes of transmission like contaminated surfaces or close contacts between people in such indoor environments might also have explained the diseases spread.
WHOs stance also recognized the importance of people spreading COVID-19 without symptoms, a phenomenon the organization has long downplayed. ............................................

Letter from 239 scientists: "Time to Address Airborne Transmission of COVID-19"
Bottomline: Time to guard against inhalation of microdroplets -- small droplets that don't fall to the ground within 6ft but travel longer distances and remain suspended in air.

We know viruses are released during exhalation, talking, and coughing in microdroplets.
Studies of SARS-CoV-1 points to airborne route; every reason to expect that SARS-CoV-2 behaves similarly.
Avoid overcrowding and provide ventilation!

(3,427 posts)I recall watching videos illustrating this, and how wearing masks greatly reduces the distance the small particles travel, at least two months ago. Apparently the WHO was slow to acknowledge it.

(22,100 posts)I have a friend who occasionally talks to research doctors. He said they told him the virus can actually be expelled 32 feet, but they had to say 6 feet is a safe distance because no one is going to stay 32 feet from anybody else.
