📍My god… the upgraded warning #B16172 variant (magenta) is surging so fast. Epidemiologists now estimate it is 60% faster than even #B117 UK/Kent variant, which is already 50% faster. If true, it could make it fastest transmission one to be found worldwide. Thread 🧵. #COVID19 Image
2) #B1672 has become quite dominant in India 🇮🇳 sequenced samples in @GISAID data. And it is projected to take over further by June. Figure from @TWenseleers.

Some say it could be due to sampling, but Tom doesn’t think so because #B16171 wouldn’t be selectively withheld. Image
3) @TWenseleers used his methods from earlier paper to estimate the new #B16172 transmission being 60% fast than the U.K. Kent #B117 variant.
4) the Brazilian #P1 variant m, despite being 2x faster than original strain, would be actually slower than the #B16172 if put into head to heads transmission competition.
5) And now #B16172 is surging in the UK too. Someone poke Boris Johnson to wake up.
6) the new UK data on #B16172 surge from @sangerinstitute is reliable because it excludes travel sequenced cases and excludes screening.

UK data even suggested #B16172 could even by 2x faster (not just 60% faster from India 🇮🇳 data above) than the #B117!! Wow. 👀
7) The World Health Organization said that the coronavirus variant first identified in India last year is being classified as a variant of global concern, with some preliminary studies showing that it spreads more easily

8) Its surging across UK. #B16172 is the new variant that we faced with in addition to #P1.
9) #B1617 lineages are surging worldwide.

Nobody is safe until we are all vaccinate.
10) surging even in wealthy Singapore
11) To be clear, we think the #B16172 Indian VOC may be ~2.6x as fast as original strain, and 60% faster than #B117 from UK/Kent. #P1 is thought to be 2-2.5, but we haven’t seen P1 and B16172 sufficiently together in same place yet in a head to head comparison to know for sure.
12) yes the US has more vaccines than India. But we are seeing #B16172 rise even with high vaccinations in the UK. And again, not all vaxxed.

also THINK OF THE KIDS… tens of millions of kids aren’t vaccinated or even eligible yet… cough… #LongCovid @LongCovidKids… cough.
13) India variant #B16172 in the UK. Anything out of the ordinary? No? Move along.

(Ht @Dr_D_Robertson ) Image
14) Bad news from UK 🇬🇧 SAGE govt report on the #B16172. It’s blazing fast. https://t.co/m36AINf9oO

SICKENING—Trump’s DHS just deported a surgeon from Brown University Medical School—who is here legally on an H1B visa that doesn’t expire until 2027, and has committed no crimes. Trained in the U.S. at Ohio State, University of Washington, and Yale as a **transplant surgeon** (one of the most difficult surgical fields in all of medicine!!!), she is a highly trained doctor on kidney transplants, which cannot be easily replaced. Her phone was seized at the border. A federal judge handed down an injunction against her deportation—but she was already deported on a plane en route to Paris. Brown’s kidney transplant clinic is now strained by her deportation.Image

PROVIDENCE — A Rhode Island doctor who had traveled to Lebanon to see her parents was prevented from re-entering the United States at Boston’s Logan International Airport on Thursday evening, her lawyer and a colleague said.

Dr. Rasha Alawieh, 34, who lives in Providence, has been working at Brown Medicine’s Division of Kidney Disease & Hypertension since last July, and she [has] been part of the transplant service at Rhode Island Hospital, according to Dr. George Bayliss, the organ transplant division’s medical director. She has been studying and working in the United States for about six years, he said Friday.

The US consulate in Lebanon had issued her an H-1B visa, which is given to people in specialty occupations requiring expertise. The visa was valid through mid-2027, said Thomas S. Brown, an attorney representing her and Brown Medicine.

Alawieh was detained when she returned to Logan airport, and family members are afraid that she is about to be deported to Lebanon, he said.

“We are at a loss as to why this happened,” Brown said. “I don’t know if it’s a byproduct of the Trump crackdown on immigration. I don’t know if it’s a travel ban or some other issue.”

He said her phone has been seized and he has not been able to contact Alawieh.

Bayliss said a lawyer filed a petition with the US District Court in Massachusetts, and Judge Leo T. Sorokin issued an order saying Alawieh should not be moved outside of Massachusetts without 48 hours notice. But he said that message apparently did not reach immigration officials in time, and a plane carrying Alawieh left for Paris.

“This is outrageous,” Bayliss said in an interview. “This is a person who is legally entitled to be in the U.S., who is stopped from re-entering the country for reasons no one knows. It’s depriving her patients of a good physician.”

A US Customs and Border Patrol spokesperson, Ryan Brissette, was not able to immediately answer questions about Alawieh on Friday evening.

Bayliss said Alawieh graduated from the American University of Beirut medical school and came to the United States for a nephrology fellowship at Ohio State University. She then landed a transplant fellowship at University of Washington and had a residency in the Yale hospital system before starting at Brown Medicine last July, he said.

“She’s really a very humble and able person,” Bayliss said. “She takes care of her patients. She is talented and thoughtful and a great addition to our division.”

Bayliss said Alawieh went to Lebanon to visit parents and planned to be gone for two weeks. He said she texted a colleague at 6:30 p.m. Thursday saying she was back in Boston, but then her family heard from immigration officials.

Dr. Paul Morrissey, surgical director of the organ transplant division at Brown University Health, said Alawieh works on getting people in Rhode Island on the list for a kidney transplants, and that’s a crucial job at a time when there has been a lot of focus on the need for kidneys and their equitable distribution.

He said Alawieh should not have had any problem traveling out of the country with an H-1B visa.

“It’s an unfortunate set of circumstances,” Morrissey said. “It’s putting a strain on our office. Her work has been exceptional.”

3) There is a new Trump ban against many countries, including tourist visa bans against all countries in the red and orange lists. This list is still tentative. And it shouldn’t have affected people with existing visas, such and the Brown kidney transplant surgeon Image

I’ve said it before, and I’ll say it again… once upon a time, liberals did have our own “Leftist Joe Rogan”… his name was Joe Rogan…

Here he is advocating for socialized medicine, healthcare for all, and supporting labor unions to protect workers.
2) Recall, Rogan was once pro Obama and pro Bernie Sanders, and pro Yang Gang, and anti Trump. It’s sad he has since failed to the dark side. But like Vader… maybe he can be redeemed someday and come back to the light.
3) *Fallen, not failed (above).

Joe Rogan was also pro gay rights and pro DACA and pro helping inner city communities that suffer economic and social injustices. It’s sad what he has become. I feel we should try to pull & welcome him back someday. Everyone can be redeemed.

BREAKING—FDA suddenly cancels meeting to update next season’s flu vaccines, with zero explanations. Any delays will jeopardize next year’s vaccine supply chain. Image
2) Folks who follow me know that I’m no bullshitter. I criticized past pandemic response right and left, and have called balls and strikes without bias. And I often say things that doctors & epidemiologists are whispering among themselves but don’t say publicly. (Cough cough) ⬇️
3) While I don’t recommend hoarding… I think stocking up on flu antivirals, which you can obtain prophylactically (preventively) from doctors if you ask nicely why you’re high risk, can be a good idea. I know many doctors, epidemiologists and virologists who do for their family.

Doctors are debunking RFK Jr’s claim that 20 hospitalized measles cases in Texas are there for mainly quarantine. Doctors on the ground say the 20 kids hospitalized are having trouble breathing. Oh and they are all unvaccinated against measles, which RFK Jr neglects to mention. Image
2) RFK Jr told Trump today there’s now 2 measles deaths.
3) RFK Jr is a tear with his FDA today. A dark Darwinian future lies ahead for America.

BREAKING—Reports coming in about potentially *2 measles deaths* in Texas, not just one, according to an HHS briefing to the White House today.
2) Earlier today, one measles death in an unvaccinated child was reported in Texas. Image
3) It seems to be RFK Jr who said it in an official Trump WH cabinet meeting today. Not saying he doesn’t lie, but he is now HHS Secretary

Woke or biology? There are actually more than the basic “male” XY & “female” XX sexes. Why? Because biology also creates people with single X chromosomes, or extra chromosomes like XXX, XXY, XYY, or XXX+, plus many 🧬genes. 👉All I’m asking is— please be kind to others. Thanks🙏 Image

2) “The most frequent SCAs include Turner syndrome (45,X), Klinefelter syndrome (47,XXY), Trisomy X syndrome (47,XXX), and Double Y syndrome (47,XYY).”

pmc.ncbi.nlm.nih.gov/articles/PMC10…
3) “The phenotype seen in SCAs is highly variable and may not merely be due to the direct genomic imbalance from altered sex chromosome gene dosage but also due to additive alterations in gene networks and regulatory pathways across the genome as well as individual genetic modifiers.”
