I'm not sure I have the time to explain just how much information is out there so I am just going to post screenshots of articles dealing with airborne/aerosol spread until I get tired.
Lancet, 50s?
80s I think?
1972
air sampling culturable bacteria
2002
Measuring proteins in the air bc they bother the throat, I think.
book review from 1986 of an aerosol textbook where the reviewer says it would be useful to occupational hygiene
investigating fates of particles in infection control rooms, with improved ventilation set up proposed
Newcastle disease - I don't even know what that is, but in 1983 this was written mentioning that people thought it might spread through the air.
Lancet 1994
"Airborne transmission plays a major role in the epidemic spread of some of the most virulent human pathogens"
2003
Can't very well leave that title out here without also posting the authors' conclusion. So here it is:
1998
From 1938, suggesting ventilation worked very well for TB and might work in fever hospitals as well
1890
Yes, 18.
1934
1936
1/4 Lancet 1938 saying strep definitively through the air
2/4
3/4 about measuring colonies from the dry particles
4/4
good little blurb about patients coughing and how they found that the strep in the air was the same strain as the patients had
That's about 1/4 of what I happened to collect in that directory, which of course isn't at all what's out in the world but just whatever I happened to store there. I'll continue later...
I know you will be sad until my return, so I will give you this book search for "airborne virus"
I also recommend #20 which is a WHO report about dampness in buildings and organisms n the air, in which it says:
1938 and still applicable, TO THE WORD, today.
Talked about this one, from 1938, in another thread.
1939
1939 talking about using "aerosols" meaning particles of disinfectants, to kill airborne bacteria. See picture lower right. I've talked about this before.
1939
1940
1941. This is the study that some people say "ferrets are not humans" to. So, apparently ferrets can flu through the air, but human flu is much much heavier - maybe say ten pounds per virion? - and falls straight to the ground.
Right.
Whole book 1940-something about aerobiology
Laid out agar plates and grew bacteria blown out of the ocean.
Love the typesetting.
Oh, and the trying to stop people from dying.
Famous. Explosive outbreak of flu on a plane stopped on the tarmac for three hours. Plane ventilation was turned off.
Can you believe some _ have written that "the people were allowed to walk around so they might have spread it by droplets?"
Mad libs. Fill in the blank.
We're just to the 80s now.
Riley was Wells' protegee.
Both famously spent their entire careers on airborne spread of pathogens.
"The Johns Hopkins School of Hygiene and Public Health"
Must be some amateur hour nut club never heard of it.
I could never find this article but want it.
Legionella is a bacteria. So if viruses "fall to the ground" as some _ say, bacteria must REALLY fall to the ground.
Mad libs again. Let your imagination run wild.
Summary TB. Says airborne in there.
Outbreak of flu at a naval base and on a plane.
Read first sentence
Talks about masks working to reduce droplet expulsion, shared airspace not leading to a lot of transmission (in this case) and greater risk when eating (sound familiar?)
We have just entered THIS CENTURY.
Yes, we have reached the year 2000.
First sentence.
Posted earlier, I believe.
Hilariously comments that "strong inverse relationship between ventilation and whether mice give flu to other mice" has been shown, but goes on to question whether we can extrapolate those results to humans.
Get new excuses. These ones bore me.
Example of a portable HEPA used during SARS in hospitals.
Where are they now? Hmm.
Could be used in schools and businesses I suppose if anyone cared to actually do something about this problem.

Missing some Tweet in this thread? You can try to
force a refresh
Ontario engineers and scientists now taking up the mantle and pushing for Ontario to recognize air transmission, to which the gov responds with the usual blathering response about "not through an air vent yet"
Lest there be any confusion at all, this is an excerpt from a 1980s article citing back to the 1930s/40s that measles was proven to be in the air. So no, this is not new. And in relation to coronaviruses, animal coronas were known to be in the air, and SARS and MERS suspected
And of course this needs to be reflected in HCW precautions, which still reflect droplet + N95 for aerosol-generating procedures only
