⚠️Confirmed—#DeltaVariant is by far the *most contagious** variant found to date, with a transmissibility that is ~2x faster than older strain. #P1 is 2nd fastest, says @WHO study.🧵
2) “Effective reproduction number of SARS-CoV-2 variants of concern/interest compared against each other, 64 countries, data until 3 June 2021” eurosurveillance.org/content/10.280…
3) “Of the six variants currently designated as VOI, five were considered in our analysis and among these, only B.1.617.1 (#Kappa) and B.1.525 #Eta demonstrated a statistically significant increase in the effective reproduction number of 48% and 29%, respectively.”
4) To be clear, “faster” transmission of #DeltaVariant means “change in effective reproduction number of SARS-CoV-2 variants relative to non-variants” (from 64 countries through 3 June 2021).
➡️Thus if the original Wuhan 1.0 strain had an R0 of ~3.5, x2 for #Delta—to get 7. 👀
5) Notice how the “other” older strain (non-VOC/VOI) in dark green have all but disappeared from most countries. #B117#alpha came to the scene during the winter, and #P1#Gamma dominated Brazil and didn’t let #Alpha take hold.
6) Also, the other India-origin varian #Kappa#B16171, while not officially a higher-risk-rated VOC, seems to be faster than the VOC’s #Alpha#Beta, and maybe #Gamma. I think #Kappa deserves to be upgraded. It’s found in outbreaks in Australia 🇦🇺 at the moment.
7) The new #DeltaVariant faster transmission data is why @WHO declared it a VOC 3 weeks ago in late May. UK 🇬🇧 declared Delta a VOC 2 weeks ago… but US CDC only declared Delta a VOC… 2 days ago.
9) Sorry, I’ve been super annoyed at the slow movement of the CDC to act and warn about the #DeltaVariant. They were relatively quite while rest of the world scrambled to contain the #B16172 variant from India— sometimes warning VOC status 3 weeks is just too late.
10) I’ve been fuming for a while—because CDC should have acted when it saw clear data on #DeltaVariant consistently soar like this across many states. We have lots precious time.
11) #DeltaVariant also is more confusing to identify - it mimics the common cold, and the classic #COVID19 symptom of loss of smell is much more rare! This is a huge change.
12) When I see #DeltaVariant stats like these… I get worried. Granted, many of the double vaccinated are more elderly in the UK, but that doesn’t bode well for elderly protection then.
13) Similar #DeltaVariant worries from a 🇨🇦 hospital— ➡️Outbreak even w/ 2 dose of mRNA vaccines—16 patients & 6 HCWS #DeltaVariant positive. 6/16 patients & 5/6 HCWs had received 2 doses of #COVID19 vaccine. A 2x vaccinated 80-year old also died. cbc.ca/amp/1.6063802
14) Here is a BEST EXPLAINER video on #DeltaVariant. Part 1 of 3.
15) again, @IndependentSage also emphasizes that people who are either elderly or have morbidity may be even more susceptible to #DeltaVariant - even if vaccinated.
17) the main problem with #DeltaVariant is that the 1 dose strategy isn’t good anymore. 1 dose vaccine efficacy is likely just ~33% or so with either AstraZeneca or Pfizer. That is trouble for millions that aren’t two dose vaccinated yet.
18) back to the age issue, notice how virus neutralization drops with age. Problem with #DeltaVariant (right) and vaccine is that among young adults, they start at lower vaccine neutralization level than even an elderly person with original strain!
19) Now the crisis—Let this sink in—over 100 US counties right now have <20% of local population vaccinated. That is a “time bomb waiting to happen” says Dr @mtosterholm.
This will not end well low vaccinations area of the US & around world. #COVID19
20) And now @WHO_Europe chief says #Delta is soon going to take over Europe as well. Most countries in Europe are not acting quickly or at all. This is Germany right now… #DeltaVariant (brown) is soaring. #P1 Gamma is tagging along and rising too.
21) MORE SEVERE—UK scientists found #DeltaVariant to have 2.4-2.6x higher risk of hospitalization than B117 #AlphaVariant. But Alpha is 64% higher risk than original for hospitalization. So 1.6*2.5= 4.1x. That’s why Delta likely has 4x higher hospitalization risk than original ⚠️
22) Bottomline: #DeltaVariant is the most contagious fastest spreading variant to date. It’s more severe, and while 2 dose efficacy is good, Delta has 1 dose vaccine evasion—that is the “problem” as Dr Fauci put it. And most folks aren’t 2 dose vaccinated.
23) Regarding J&J, I have no direct evidence-based position. However… it’s not technically a 2-dose vaccine. if you’re interested what some immunologists think… read thread 🧵 below… but the CDC needs to put out guidance on this soon. Very soon.
25) In case anyone had any doubt how utterly dominant #DeltaVariant is— it just hit 99% of all #COVID19 cases in the UK. The US is where UK was in late April / early May.
26) please sign the petition to CDC for urgent #DeltaVariant action. It is by @endCOVID19 & @CovidActionGrp and a “coalition of scientists, public health officials, epidemiologists, health care workers, educators, advocates, parents, & concerned citizens: change.org/p/centers-for-…
27) folks— we seriously need to act, and act damn fast. #DeltaVariant is going to be a serious scourge for many countries around the world soon, not just for India and UK. US is on the tipping point… see thread 🧵 below.
29) we must also be vigilant about #DeltaVariant and school children. Kids can transmit very efficiently. And kids can get #LongCovid too - 1 in 12 in fact.
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.

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
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.
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.
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.
2) RFK Jr told Trump today there’s now 2 measles deaths.
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🙏
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).”
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.”
