A quick thread.

Literally, because I opened this PDF.

pubmed.ncbi.nlm.nih.gov/23771256/
Viruses able to be spread by airborne can also spread over short.
1966, adenovirus isolated from aerosol samples
1970, enterovirus isolated from aerosol samples
potential large number of hosts
Controversy because (a) R lower for flu, so see less over distance and (b) if hospitals had to use airborne for flu, would cost a lot.
Virus found in respired breath.

Interruption of influenza by UV irradiation of upper room air (3 references)
Found in air
Found flu RNA in air
Probably aint yer hands, you dirty monster bros
Transmission during air travel documented, and hard to measure.
RHINOvirus
70% secondary attack rate. Must be airborne then, right? ;)
By touch etc but also ... by aerosols:
THE RONA

Our most favourite friend
Transmits mostly at close range (of course, as aerosols do) but airborne also known.
Including on a plane
... 7 rows ahead ...
... same floor of hotel (Metropole) ...
... and Amoy Gardens, which was aerosolized via the sewage system. [ed, was most definitely not rats]...
ADENOVIRUS
Can lead to persistent infections ... shedding for months ...
Transmits by all modes, which is to say, aerosol short and long, and touch

[ed. sorry droplet, and also touch, good luck with that]

Inhalation takes only small doses to infect.
Detected in the air by real-time PCR ...
Detected in various indoor environments, but of course data sparse because as the EXPERTS have said, isolating from air is difficult - you tend to crush up the virus.
RSV

The babies' revenge!
What? 100%?

Then it simply _has_ to be airborne like measles [ed. lifts pinky, sips tea]
Disgusting huge discharges from the nose ...
Controversy here.

Controversy here?

[ed. not really. Those are poorly designed studies, misusing p-test, on tiny N samples of babies to "disprove" aerosol. When a baby belts an opera, I'll reconsider]
RNA found in air 7m from patient bed.

Inb4 not live virus. Again, remember, hard to sample actual virus. Rawr.
Found throughout hospital, in aerosols.
Article ends with GI virus, which can be aerosolized by vomiting. Explosive outbreaks, but still thought to be by touch, although air spread not much studied . Going to skip this one because it's a bit off base, except one though ...
... infection is a numbers game. Up to a trillion copies per gram feces egested.
Le fin.

Remember, a close contact by any other name would aerosol as sweet.

#COVIDisAirborne
In these papers, comments about infection at close contact do not tell you HOW infect, b/c aerosols infect at close AND long range

Dividing viruses into short and long range by HOW INFECTIOUS they are is fine, but once call short "droplet" & start to believe it...thats the error
(not really by touch)

Has anyone worked up the ladder of denial for bird flu?

- We have not found bird flu.

- We have found bird flu in one bird. There is no evidence of bird to bird transmission.
- We have found bird flu in many birds and there is bird to bird transmission but it has not moved to other mammals.

- We have found bird flu in a cow. However, we have not found evidence of cow to cow transmission.

- We have now found bird flu in many cows.
- We have now found evidence of cow to cow transmission but we do not know how this is happening.

- We found some bird flu in the milk. You should not worry because this might not be live virus. However, for some reason, we now think milk is the vector of transmission.

I'm so fed up with people taking the WHO seriously.

This is from 2014. Image

They already said "airborne" although they had said long-range (throw back to 1910, by the way)

But wait for it Image

Wow they buried the lead.

COVID might be up to an R0 of 24, eating measles for breakfast. Image
Very comparable at median of 11 to measles, which is probably 9 to 12.

Anyway from p. 19 iris.who.int/handle/10665/3…
And measles from much much older reports...

Somewhere I posted an article that looked at how they arrived at 12 to 18 and concluded it was more like 9 to 12. Probably on the low end too.

For anyone reading this, he means "Airborne" as in the three viruses that require Airborne precautions.

Those are _defined_ as TB, measles and chickenpox.

They are "airborne" because they are "Airborne."

It is totally ludicrous, yes.
It means negative pressure rooms and N95s, which is why they desperately do not want COVID to be called "Airborne".
This is why, during SARS, when a roomful of Canadian doctors and nurses got sick even though they were using "Droplet precautions" (I'll capitalize) - that is, medical masks - they invented AGMP, so they could explain how a droplet virus infected people using Droplet Precautions.

⚠️Please people.

We are no longer calling it "fire".

It is "potentially harmful chemical combustion energy output".
This of course means the fire department will be renamed as well.

It will be called the "organization for the suppression of potentially harmful chemical combustion energy output situations."
And please do not ask them to get your cat out of your tree. They will not understand.

It is an "affective feline mammal trapped in a heightened potential energy state of arboreal origin."

@mvankerkhove @CIDRAP @WHO Thanks.

Seems most health care locations (in Ontario) ignore the WHO. That's too bad.

This is December 2020 for anyone who wants it.
