Receptions outdoors? Can one fall in love with a conference? Pitter patter.
No one but us transmission prevention specialists know that transmission can still happen outdoors. But. Super-spreading is bloody well much less likely to happen.
So kudos.
Testing with 24 hours of conference start?
Rapid testing? Every day?!
"Have the bivalent boosters - or you are dead to us.".
Would have loved to see #corsirosenthalboxes or HEPAs involved. Headband N95s instead of KN95s (60-70% fake on Amazon), as those earloops slowly ease forward.
And of course, having virtual - but they went out of their way to talk about that...this entire clip is about it.
So, not perfection, but you can tell they are trying, and have done a fine job.
And that's 1000% better than some of the others we've seen.
Despite the pore sizes of the N95 filtration being so much larger than CO2 molecules, there is a greater concentration of CO2 in the N95, than outside.
Why?
We exhale 4–5% CO2 (40,000–50,000 ppm), much higher than the ~0.04% (400 ppm) in ambient air.
What is the the AVERAGE CO2 in the dead space below an N95? 1-3% - or 10,000 to 30,000 ppm.
Sounds scary high, right? It's the AVERAGE. Below you can see it rise and fall. See how at the end of the inhalation it's almost zero?
But what happens to that CO2? We inhaled it
all, so we must be poisoning ourselves!?
Nope, here is what is going on with our alveoli gas composition.
Not much of a change.
And that gets reflected in the amount of CO2 in our blood.
That is best measured by PaCO2 (arterial CO2 partial pressure).

71 guinea pigs gave their lives between 1956 and 1958 in the eponymous study by Riley et al, getting TB air piped in from some TB patients, to prove TB is airborne.
Influenza is kind of airborne per most doctors. But kind of not.
So....

We need some volunteers.
Will horses be those volunteers that finally lay it all out?
Yes - but none of them lost their lives.
Air samplers were deployed and tracked horses inoculated with Equine influenza virus (EIV).
From the very first day post inoculation (dpi), until the
12th day, EIV was found in the air, in this new study.
With no horses, or guinea pigs, hurt in the process.
But sure, influenza's not airborne - if you are the USDA, right, @nirav_maine?
@ThailandMedicaX, retweeted by some because of their controversial takes (ahem, their lies?), is saying that FAR-UVC is dangerous because somehow the light will get into the lungs.
Lol.
They are just apparent supplement grifters.

I noticed they were using @NukitToBeSure's excellent torches as their example picture.
Strange to be so selective of an example picture for someone purporting to be an independent news source on health.
Hmm. I helped defend Nukit against charges of
racism by a very nasty couple who it turned out just do not like UVC, personally. I wonder....
Yep, ThailandMedicalX has blocked me.
But, it's weird for a purported news source to block someone like me @gorskon
