Asymptomatic transmission of CoVid. Remember that discovery?

That was it! Everyone knew it had to be airborne. No symptoms means no coughing, and no droplets.

Airborne.

A quick thread on 3 asymptomatic transmission cases.... of Monkeypox.
Let's go to Belgium!

Specifically, a large Belgium STI clinic. They tested swabs collected back in May.
And found 3 individuals who tested positive for monkeypox.

No symptoms. But had monkeypox.

How do we interpret this? Let's let the author do the honors.
Close contacts can transmit with no symptoms.

So, how does the virus get from one person to the other?

Nobody says and sprays it, that much.

Nobody licking doorknobs.

But friends chatting by the water cooler? Exchanging aerosols?

Happens all the time.
Thanks to @fitterhappierAJ for the intro picture.

Thank you to @IrithItm, I believe, who appears to be one of the authors of a fascinating study.

That may just have changed the world for a little bit better.
Thank you, and welcome to the thread, as I did not know that!

@threadreader unroll please
Thank you for the further evidence of Monkeypox asymptomatic patients!

Given that SARS1, Influenza, CoVid, chickenpox, measles, etc all have transmission either presymptomatically or asymptomatically?

Monkeypox will also fit in there, too.

Just a little bit closer to acknowledging H5N1 is airborne.

3 vets asymptomatic, + for bird flu antibodies. Did not wear respiratory gear or glasses.

Did wear gloves and coveralls - so rules out fomites.

One practicing in states with NO H5N1.

Vets get very close to /1 No seropositive practitioner knew that they were working with dairy cattle with known or suspected HPAI A(H5) infection. None of the seropositive practitioners reported wearing respiratory or eye protection while providing veterinary care to cattle. Neither respiratory or eye protection is recommended when working with uninfected animals in regions without confirmed cases; however, safety goggles and a respirator are recommended when working with uninfected animals in regions where there are confirmed or potentially infected animals (4).
Among 150 bovine veterinary practitioners, three had evidence of recent infection with HPAI A(H5) virus, including one who only practiced in two states (Georgia and South Carolina) with no known HPAI A(H5) virus infection in cattle and no reported human cases (1,2); this practitioner reported no exposures to animals with known or suspected HPAI A(H5) virus infections. These findings suggest that there might be HPAI A(H5) virus–infected dairy cattle in states where infection in dairy cattle has not yet been identified, highlighting the importance of rapid identification of infected dairy cat...
aerosol sources. Aerosol orifices.

This lines up with previous studies.

Latest Pew Poll.

Or an exercise on "How well did Biden disappear C0V1D?"

On one hand, 21% of Americans still view C0V1D as a major public threat 21% of Americans still view COVID as a major public threat.
On the other hand, still masking?

6% of Democrats
4% Americans
2% Republicans

Guess when Biden took over on the graph? On the other hand, still masking?  6% of Democrats  4% Americans 2% Republicans  Guess when Biden took over on the graph?
Yes - pretty much as soon as Biden took over, he began disappearing C0V1D.

BTW, the last poll was by yougov - masking was at 12% last year. On the other hand, still masking?  6% of Democrats  4% Americans 2% Republicans  Guess when Biden took over on the graph?

What do we need to do to make every healthcare worker in the world understand that flu is airborne?

Get IPC on board.

Let me introduce you to Dr. Zahir Hirji, President of @IPACCanada at #IPAC2023.

Where do we know him from?

That's a very interesting question.

/1 Image
In 2006, Dr. Tellier wrote an article in the CDC EID explaining that influenza was airborne via aerosols.

Quite nicely done.

pmc.ncbi.nlm.nih.gov/articles/PMC33…
Dr. Zahir Hirji and some other IPC doctors from the Canadian HUGE University Health Network disagreed.

Right back you, Tellier - in 2007.

Normally I do not retweet unsourced material, unless it's a personal story I think you might be interested in.

But.

AGI scares the daylights out of me.

Because I personally have the knowledge and ability to source a truly pathogenic COVID, aerosolize, and release it.

/1
If I can do that? Any AGI can.

And it is an easy logical step to remove most of humanity to restore balance.

It would be foolhardy as people would adapt, and begin N95ing their lives - but I could see an early AGI make that leap.
Srcs here. We really need to have an AI Doomsday Clock.

This is a very big deal. D1.1 now in cattle.

D1.1 has put 100% of the people it has infected into the hospital - and killed 50%.**

BC teen had to be intubated on ECMO - despite age and no preconditions.

Louisiana man died in the hospital.

aphis.usda.gov/news/program-u…On January 31, 2025, the USDA Animal and Plant Health Inspection Service (APHIS) National Veterinary Services Laboratories (NVSL) confirmed by whole genome sequence the first detection of highly pathogenic avian influenza (HPAI) H5N1 clade 2.3.4.4b, genotype D1.1 in dairy cattle.
** The numbers of those severely impacted SHOULD drastically go down as doctors become aware of the importance of ruling out H5N1 much quicker.

The teen had delayed care, and that is one possible reason for the severity of their infection.

** We need more numbers infected to
see if the severity is truly wide-spread - or did we just have a couple of very unlucky people.
