Swabbing correctly for #COVID19? Most are not. @IamKGB tests—

1) VERY POS—back of throat, cheeks, roof of mouth & both nasopharyngeal w swab held in place for 10s.
2) NEG—outside portion of nostrils
3) NEG—anterior nares/nasal septum
4) FAINT POS—throat & cheeks
5) Repeated #1
2) I have long warned that we need to swab the mouth and nose together. But now it seems also **swabbing the cheeks & holding the swab for an extended time** may be better than just nose or throat alone or together without cheek!
3) Been advocating for *both* throat combined with nose swab for weeks. Both the science and lots of anecdotes supports it. Many countries do it too—but cheek swabbing for extended time is new swab approach.
4) Another good story was a good real life example how a nasal test came up short but combining with throat it was able to detect it. The above experiment does support that throat and nose together is better. But now it seems adding cheek could be maybe even more improvement!
5) Good thing we got variants that maybe might evade future COVID tests under control… oh wait…
6) Well at least we have virus transmission under control so that we don’t develop more mutant strains… oh wait… never mind we are just letting the virus roam free, even in hospitals and nursing homes!!! 🤦🏻‍♂️
7) most people don’t do nasal swabs correctly. Here is how by @DrEricLevi:

➡️GO LOW. GO SLOW.

Going up is painful.

Going fast is interpreted by the nose as pain.

Going low and slow reduces pain and allows time for swab to absorb samples.

Rotate gently.
8) If swabbing your mouth and nose (combined oral and nasal method):

Do NOT eat, drink, chew gum, smoke, or vape for at least 30 minutes.

Blow your nose before the test.

Do **nose, cheek, & throat** (all three)

📍VARIANTS OUTLOOK—I’m old enough to recall a few smug virologists who were adamant that “#SARS2 don’t mutate much”/ “re-infections impossible”—then tried to silence & shame anyone warning about reinfections. ➡️Well, here is our #COVID19 winter roadmap—many are immunity evading👀 Image
2) Here is what you need to focus on —it’s scary how now there is **CONVERGENT EVOLUTION** of very specific combinations of mutations that are showing up together across many different Omicron family trees. They all are converging to IMMUNITY EVASION. Image
3) I’m also old enough to have seen the #COVID denialism and minimizers become wrong TIME AND TIME again… each time dismissing restrictions and then each time claiming “nobody could have foreseen this” sudden hospitalization surge! UK 🇬🇧 hospitals for example… HT @TRyanGregory Image

📍89.5% of the US is still in HIGH or SUBSTANTIAL transmission of #COVID19. Yet @CDCgov thinks nursing homes & hospitals no longer need masking. This is the last straw—hell has frozen over & @CDCDirector Walensky is now truly compromised. This is a very sad day. #CovidIsNotOver ImageImage
Here is what lays in our future. The variants of Omicron are exploding. And worst thing is that many are CONVERGING their mutations to very unique combinations of mutations that likely evade immunity. Mutations from many different trees don’t usually converge unless good reason.
3) This is an absolute A+ quote by @JeromeAdamsMD here: “"This nuanced have your cake and eat it too approach hasn't worked A SINGLE TIME throughout the pandemic. People hear 'no more masks!' "

2) Outbreak at a glance
On 20 September 2022, Uganda health authorities declared an outbreak of Ebola disease, caused by Sudan virus, following laboratory confirmation of a patient from a village in Madudu sub-county, Mubende district, central Uganda.
3) As of 25 September 2022, a cumulative number of 18 confirmed and 18 probable cases have been reported from Mubende, Kyegegwa and Kassanda districts, including 23 deaths. This is the first Ebola disease outbreak caused by Sudan virus (SUDV) in Uganda since 2012.

More than 800 participants—About ~1/4 of 3400 attendees surveyed, including dancers, of this year’s Awa Odori festival 🇯🇵held from Aug. 12-15 were infected #COVID19. Likely higher since many didn’t respond. Similar thing at Burning Man this year too. Sigh.
asahi.com/ajw/articles/1…
Burning Man had reportedly a huge outbreak too this year of #COVID19. No official tallies (cuz it’s Burning Man), but lots of reports of COVID among returnees.
3) “According to organizers, anti-infection rules in its guidelines were largely observed.
However, some of the guidelines, including avoiding the “sanmitsu” (the 3 Cs of closed spaces, crowded places and close-contact settings) in dressing rooms, were not strictly adhered to.”

Once upon a time, kids were allowed to smoke 🚬 . We stopped exposing kids to cigarettes when we learned it was bad. ➡️We now know #COVID harms kids’ brains & health. Yet we somehow keep letting kids get exposed to the harmful virus & #LongCovid. Find some humanity. Protect kids.
This is chart showing pediatric hospitalization for #COVID19 surging 45% in just 2 weeks in England. No, the kids are not alright. Stop this madness of infecting kids. Protect them damnit.
Reminder— Kids do indeed get sick. And do indeed get #LongCovid too. And they do transmit to other families. You cannot deny the dangers.

Incredibly sad—material to make 5 million N95 respirators are going to be just thrown away. All because the public now misled that the “pandemic is over”. Wait until the winter surge comes—we will regret this. #CovidIsNotOver #MaskUp

Thanks for sharing @larmbrust
2) And hell no, the pandemic is definitely not over whenever it’s killing this many people per week… ranked as #2 killer as of early September.
3) unless we change course, we will be on this high death rate plateau for quite a long time. And winter will inevitable bring a bigger surge.
