I get it. You need a place to decompress.

So, the Covid Careful tend to take umbrage to outdoor transmission studies.

Outdoors IS safer. But study after study has shown outdoor transmission.

As do these 2 studies.

Catching Covid Camping.

🧵.

I deliberately began this thread with white men, because the only countries doing these detailed studies are Asian countries. As is this one.

But every time, a tinge of ethnocentrism creeps into replies. Please keep this in mind :) .
Many don't know that measles is airborne outdoors based on an hour long conversation with a young boy and his family, after the Special Olympics. No CCTV. No credit card tracing. No GPS.

Our first study? July 24–26, 2020. South Korea. South Korea had done an
amazing job, total 13,970 cases, with 51.63 million people. Population density 515versus 35 inhabitants/km², and an older population.

In comparison, US had had 4,639,523 cases, 330 million people.

Study here.
worldometers.info/coronavirus/co…
jstage.jst.go.jp/article/jea/34…


13,979 cases in South Korea total by July 24, 2020
4 million cases in USA by July 28, 2020
Population density South Korea 515 versus USA 35 inhabitants/km², and an older population..
The reason the number of cases is important? Low background transmission.

6 families (3 each) went camping, 18 people. 10 ended up positive - 55.6%.

They took over Section 1.

There were 6 other families in Section 2- no one got infected.

There was a male/female toilet The campground was largely divided into two sections and was completely separated (Figure 1). Section 1 was a yard covered with crushed stone and Section 2 was a wooden floor. Public play facilities included a swimming pool and trampoline. Other public facilities included a sink and a male/female toilet and shower for each area. Each family moved to the campsite using their own vehicles, and installed three shade curtains and six tents in Section 1. The companions of Section 1 were involved in close, repeated conversations, eating, and drinking with the index case during the camping period,...
and shower for each area.

They basically were... camping 👇

There was no genomic testing, but as they were the only cases in the area? Not necessary.

South Korean trace and contact with CCTV and credit card are very good. It's part of the reason their case load was so low.

and installed three shade curtains and six tents in Section 1. The companions of Section 1 were involved in close, repeated conversations, eating, and drinking with the index case during the camping period, without properly following the prevention rules, such as incorrect wearing of masks while staying at outdoor tables and tents. The other 18 participants (6 teams) who used Section 2 of the same campsite during the same period were placed under passive surveillance after confirming that they had no contact wit
The evidence supporting the transmission is as follows: first, the only common place of exposure was identified as the campsite based on the location tracking by global positioning system, the history of visiting hospitals, credit card usage information for the confirmed cases without contact with previously confirmed cases; second, the region did not have an outbreak prior to the occurrence of the group; third, none of the other campers who did not have any contact with the cases were infected while staying in the same campsite at the same time.
Cctv used
So, we have the index, infecting their family, so that leaves 8 more.

As I mentioned, this is all on CCTV, with the South Korean CDC who has gone through SARS and MERS.

They are very experienced at airborne investigations, and their indoor investigations are amazing.
These experienced airborne investigators reviewed the tapes:
" close, repeated conversations, eating, and drinking with the index case during the camping period, without properly....such as incorrect wearing of masks while staying at outdoor tables and tents" Image
So, not infection in the tents. But at the tables with close, extended conversations with masks probably around chins.

If someone was in a tent, could aerosols penetrate it? Absolutely.

As I found out with a bit of Citizen Science.

Outdoors IS SAFER. Outdoor far field transmission, more than 6 feet away, is very rare due to dilution, UV, etc.

I, personally, would not camp in a campground - my risk continuum does not let me. No shame to those who do!

But life in a tent? That's tough, and ....
Brings us to this. Do you appreciate my efforts to keep you safe?

Can you help with a couple of bucks to get @rubyslippahs out of a boiling hot tent, in a campground?

She's a LongHauler who has recovered just enough to start working again and just needs a little help to
get into an apartment.

Thank you very much either way on her behalf!

Let's get back to the studies!

Got kids going to camp? My apologies, I hope they don't come home with the camp souvenir that keeps on giving. LongCovid.

Georgia, June 2020. Everyone tested. But....massive outbreak.

Measures did NOT include masks for campers and ventilation.

nytimes.com/2020/07/31/hea…



Kids hiking outdoors.
Campers and staff members were required to show proof that they had tested negative for the coronavirus no more than 12 days before arriving at the camp. Cleaning and disinfection of communal areas were enhanced; the camp required physical distancing outside cabins, and it staggered the use of communal spaces.
But while staff were required to wear cloth masks, the camp did not ask campers to do so, and did not open windows and doors to increase air circulation in buildings. The campers stayed overnight in cabins, with an average of 15 occupants in each. Many camp activities — which took place indoors as well as outdoors — included “vigorous singing and cheering,” which can enhance spread of the virus, the report said.
Of the 344 campers and staff for whom test results were available, 260 tested positive. Of children ages 6 to 10, over half were infected; 44 percent of those ages 11 to 17 were infected, as were one-third of those ages 18 to 21. Only seven staffers were older than 22, and two of them tested positive.
I try to bring "fresh aerosol eye" perspectives to every study.

This one? I'd welcome your kids home with a smile in an N95. Use the usual Covid protections of...masking, ventilation, filtration.

Like the CDC recommends for Summer Camps.



Which iscdc.gov/coronavirus/20…
no longer there. Do you know what is there when you search for summer camp and CDC? The top promoted link?

They paid for it?

Longhaulers like Amanda.

If you appreciated this chapter and its snarky coverage of the @CDCgov disappearing summer camp?

Can you help Amanda, @rubyslippahs get into an apartment?

Because she's still in a tent. So hot.

spotfund.com/story/3bb199fb…
If you learned something new like that tents do not stop aerosols (although water proofing should improve that, which I will be testing later today), can you give this thread a retweet?

Cheers either way!

People are liking... "the outdoor more than 6 feet away is very rare."

And that needs more clarification.

7 feet upwind. No problem.
7 feet downwind, probably rare, but you could catch a puff.

100 feet downwind of a person? Act of God.
100 feet downwind of a crowd? Riskier.
7 feet upwind in a light wind and they sneeze or cough? All bets are off.

This is why I respie up in the car before getting out , in a parking lot.

Holy airborne H5N1.

69 symptomatic workers, 5 positive so far?

150 on antivirals?
It's always been airborne.

This means that it is more transmissible to the humans than before.

Not Covid levels. Probably not even original WT level.

But more transmissible to the humans than before.
Homeland Security moved to Level 2.

Great summary below. Some important info not discussed by Dr. Hirschson.

This study adds to RECONFIRMING H5N1 is airborne.

Since seeing is believing, you are one of the VERY FIRST to see what H5N1 aerosols do to a cow lung.

🧵

This study is by the USDA.

As I have, & will continue to point out, @nirav_uscdc, they continue to ensure dairy workers are NOT told to wear N95s. Or PAPR as indicated would be more comfortable by @RanuDhillon @sri_srikrishna.

But worn here in their lab. By them.

Aerosols, 3-5 microns, were nebulized into the cows nostrils.

Correction to the study...SOME of those that size will deposit into the Lower Respiratory Tract. Not all. Some will deposit into the Upper Respiratory Tract.

Some will be exhaled, and inhaled again.

Can someone show me in the Secret Service manual where it tells them to stand for a photo - on order of a POTUS who has just been shot?
Amazing that the flag just happened to stretched perfectly sideways, framing Trump in that patch of blue.

The Secret Service holding him like the soldiers holding up the flag on Iwo Jima.

Like Trump is the symbol of America.

Um folks? 55 symptomatic H5N1 workers.

@amymaxmen @RickABright @Alexander_Tin @jeremyfaust @farrar
☝️☝️☝️☝️☝️☝️@JeremyFarrar
Ok, 55 could be any number of scenarios,, but poultry workers in cull operations tend to be in RPE like N95 or better.

So, most likely spread between workers at lunch, after work, etc.

But that is worse,because then we have human to human and we just wuhan'd the world.

Raw milk may have been drunk in New Mexico! But that farmer's agenda is to downplay that risk. More on him later.

My agenda is urgency.

The FDA KNEW AND SAT ON ITS VERY CLEAN HANDS, back on its very clean boots. Probably smoking a cigarette with its dirty aerosols.

🧵
The outbreak claim comes from Mark McAfee, owner of Raw Farms, a raw milk dairy producer with herds in Fresno and Hanford. On June 17, McAfee — who is also the president of the Raw Milk Institute, an advocacy group — emailed the FDA’s acting director, Donald Prater, to say that he’d been told a raw milk dairy herd had been infected and that people had probably consumed the contaminated milk.
The farmer’s cows were suffering yellowish, runny diarrhea; low milk production; THICK, YELLOWISH COLOSTRUM....

Bird flu milk on the right, as a reminder.
According to McAfee’s email, which was shared with The Times, a subset of a farmer’s cows were suffering yellowish, runny diarrhea; low milk production; thick, yellowish colostrum; and general weakness. The farmer told McAfee he had separated the sick cows — about 10% of his herd — and discontinued milking them.
Image
“The farmer reported that for certain, humans had consumed the raw milk at some level,”

“told the farmer to not report anything to anyone” because the virus would pass and “he did not want the FDA to swoop in and cause a media frenzy.” “The farmer reported that for certain, humans had consumed the raw milk at some level,” McAfee wrote to Prater, adding that the farmer’s veterinarian “told the farmer to not report anything to anyone” because the virus would pass and “he did not want the FDA to swoop in and cause a media frenzy.”

This study is HUGE FOR YOU!

Why? Every hospital, dental, and nursing home corporation around the world use studies designed by the Mark Loeb Group to keep N95s off of your HCW.

As they bend over you in a mask so baggy you can see their toothy smile.

Let me ask you...

/1
Would pulling on an N95 protect you more from airborne anthrax than if you pulled on a medical mask (MM)? From only 3 feet away?

In fact, IT IS AGAINST the proper use of respirators.

OSHA would have you KICKED off the job site.

But when Loeb did it in 2022? The $$$ 🎉🎉🎉
But - once this preprint is published? I do not see how Loeb (2022) is not RETRACTED.🔥🔥🔥

That study compared surgical masks to N95s. It said that surgical (medical) masks are as good as N95s in protection from Covid.

That they are not inferior, aka noninferior, to N95s.
