📍Delta variant #B16172:

50-70% more transmissible

2.7x more likely to be hospitalized than #B117

“Many people could end up in hospital, 🇬🇧 NHS could be thrown into another surge.”

Says @globalhlthtwit of @IndependentSage. #COVID19 #DeltaVariant
2) Latest UK @PHE_uk assessment on #DeltaVariant #B16172:

📌Severity is now RED (previously insufficient info)

📌Vaccines is now RED with high confidence (previously moderate) Image
3) Two separate studies on hospitalization severity—one from England 🏴󠁧󠁢󠁥󠁮󠁧󠁿 and one from Scotland 🏴󠁧󠁢󠁳󠁣󠁴󠁿— both found Increased severity of #DeltaVariant #B16172

➡️ Risk of hospital admission (Hazard Ratio = 2.61 in England and HR = 2.39 in Scotland) compared to the Kent variant #B117! Image
4) Keep in mind that this ~2.5x higher hospitalization risk for #B16172 #DeltaVariant versus #B117 #AlphaVariant is on top of #B117 being 64% more severe than the original earlier strain. Thus 1.64*2.5= #DeltaVariant having *4.1x* the risk of hospitalization vs original! 👀
5) How fast is #DeltaVariant #B16172 taking over the total number of cases in the UK? Pretty darn fast. It’s now approaching / near 75% of all cases in the UK. Image
6) And just how fast is it surging versus other previous variants? Pretty much the fastest known variant to date. assets.publishing.service.gov.uk/government/upl… Image
7) "Do not let this variant spread. It's a very dangerous variant” says epidemiologist Dr. @dgurdasani1. The delta variant, #B1617, first found in India, is driving new #COVID19 wave in 🇬🇧—and it's spreading quickly around the world, including in Canada🇨🇦 cbc.ca/amp/1.6050085?…
8) there is growing concern and anger by many scientists that @PHE_uk is ignoring the dangers and media is ignoring the risks
9) Other experts agree the latest UK reports on the #DeltaVariant are “grim”.
10) Pediatric cases among school age kids soaring too.
11) Why is the #DeltaVariant #B16172 so transmissible and pathogenic? Scientists think they found the molecular reason… it has enhance cleavage (activation) at a special furin site on the virus that allows enhanced human cell entry. biorxiv.org/content/10.110…
12) As a reminder, for the world 🌎 and for 🇬🇧 residents… you stand at the precipice of potentially this…. Choose wisely.

⚠️WORST FLU SEASON ever since 2002-2003 when we began to track flu (red, first graph). Worst hit this year are children ages 0-4 and 5-17. ▶️We also have significantly LOWER flu vaccine uptake this year, one of the lowest flu vaccine coverages (red 3rd graph). Indisputable facts. Image
Image
Image
2) I don't need to tell you that certain US states have vastly lower vaccination rates than others. See map (lighter green, less flu vaccination coverage), and which have higher (darker green)...

If you want to see details and demographics on which state has the LOWEST flu vaccine coverage rates... the data is here.
cdc.gov/fluvaxview/das…Image
3) It’s not just the flu that is going around… Gaines County, TX, where the epicenter of the measles outbreak is, has one of the lowest measles vaccination rates too.

INFLUENZA REACHES EPIDEMIC THRESHOLD in New York—Influenza A (Unknown variety) positivity soars (yellow), while hospitalizations stand higher than past 3 years. The rise of unknown subtyping Flu A has led NY to issue new alert to subtype all Flu A immediately for bird flu. Image
Image
Image
Image
2) This was the reason for the urgency in NY issuing an alert to subtype all hospitalized cases for bird flu if Flu A. See thread below 👇
3) the testing memo seems very aggressive for bird flu.

BREAKING—22 States sue to block Trump WH cuts to NIH research grants. Image
2) Attorneys general representing 22 states sued the Trump administration on Monday, asking a federal judge to temporarily block a major policy change by the National Institutes of Health that would substantially limit payments for research overhead

statnews.com/2025/02/10/nih…
3) In the lawsuit, filed in U.S. District Court for the District of MA, the AGs argued that NIH’s abrupt decision to set a 15% cap on payments for indirect costs would cause major harm to institution budgets, jeopardizing basic operations and medical research.

💣TORPEDOING MEDICAL RESEARCH—NIH indirect grant funding just got slashed by Trump to 15%. What does this mean for you? Colleges and universities won’t be able to support students, tuition will increase, especially graduate students & researchers who find cures/preventions for cancer, diabetes, heart disease, Alzheimer’s and more. This will not only raise tuition and hurt pipeline of future scientists/doctors, but COMPLETELY DECIMATE MEDICAL & PUBLIC HEALTH RESEARCH. It will also give more power to big pharma to manipulate research agendas and buy out ideas that should remain in the public domain. Ie THE RICH BIOTECH TYCOONS (eg Vivek Ramaswamy) WILL GET RICHER. The lay public will someday only see future drug/tech prices soar as biotech and big pharma control more science and make more money.

Also, Trump’s NIH posted this graphic - but it ignores that most public universities also heavily rely on indirect to subsidize tuition, and train next generation of scientists and medical doctors doing research. (Public colleges can’t compete with wealthier schools who do have endowments, and hence will fall further behind). Public colleges that do medical research will literally fall apart without this mechanism.Image
Image
2) People don’t seem to get 2 things:

📌Indirect funds college administration and facilities and support services. Academic advising, building operations, new labs and classrooms for students— where does that money come from? If not indirect grants, then it’ll have to come more from ⬆️student tuition.
3) Most universities don’t have billion+ endowments. Most have almost none — so when you slash NIH indirect grant funding to just 15%… it hurts small schools and public colleges the most—smaller places might even go under. Rich school survive, public schools do not.

😷Flu is so bad right now that schools across the country are closing. Schools around the U.S. are closing due to surges of flu which are sickening students and staff.

📌At least 41 states are currently reporting "very high" or "high" influenza-like illness activity Image
2) As the 2024–2025 flu season rages on with no peak yet in sight, some school systems are overwhelmed with sick students and staff.

Schools and even entire school districts are temporarily closing in Texas, Ohio, Georgia, Tennessee and other states.

3) this is promoting now nationwide testing of hospitalized flu cases for Flu A and bird flu in humans!

BAM—called it again—there is clear proof of cat-human household transmission of bird flu. CDC scientists posted the data—but suddenly deleted soon afterwards. CDC is being blatantly muzzled. Image
Image
2) C.D.C. Posts, Then Deletes, Data on Bird Flu Spread Between Cats and People

The data, which appeared fleetingly online on Wednesday, confirmed transmission in two households. Scientists called on the agency to release the full report.

3) I’ve been reading the tea leaves 🍃 lately— it’s quite clear they know there is household transmission of bird flu. Hence the final alert issued by CDC before Trump took over was to get national testing of Flu A to see if bird flu in hospitals nationwide. See important 🧵
