Studies show it can be spread by just breathing
Experts tell White House coronavirus can spread through talking or even just breathing.

[QUOTE]Fineberg told CNN this is true, but that research shows that aerosolized droplets produced by talking or possibly even by just breathing can also spread the virus.
His letter explains that research at a hospital in China shows the virus can be suspended in the air when doctors and nurses remove protective gear, or when floors are cleaned, or when staff move around.[/QUOTE]I'll go out on a limb here and suggest you can reasonably substitute the words "protective gear" with "a carrier's sports jacket" and "floors" with "furniture" in the case where a carrier or carriers have previously deposited those tiny aerosolized droplets on them. The virus particles can apparently survive for hours on some surfaces and, therefore, have a huge window of opportunity for them to be stirred up into the breathable air.
And if you think of the particles of dust you see hanging in the air when sunlight streams into a room, these virus particles are much tinier than those dust particles and might even be hitching a ride on them. Also, in real world conditions vs static, controlled lab test conditions, those particles get stirred up and re-enter the breathable air every time someone walks through a room, plops down on a couch, pulls back the drapes, opens and closes a cabinet door and so on. Or, in a restaurant, every time a server passed by your table after the woman over there flipped back her hair. Probably a ladyboy.
However, this does not fill me with alarm. Something quite the opposite, in fact. Assuming this is true, that means most of us have been exposed to COVID-19 much more often than we thought, have been introducing at least small amounts of it into our respiratory systems perhaps countless times in the past few months and yet a relative few of us have fallen prey to it and gotten sick from it.
