same thing happened in Boston in another immunocompromised person that was sick for 155 days.
JUST ONE PERSON—UK 🇬🇧 scientists think one immunocompromised person who cleared virus slowly & only partially wiped out an infection, leaving behind genetically-hardier viruses that rebound & learn how to survive better. That’s likely how #B117 started. 🧵 https://t.co/bMMjM8Hiuz

Immunocompromised 45 year old suffered from #COVID19 for 155 days before he died. The virus was changing very quickly inside the man's body\u2014it acquired a big cluster of >20 mutations\u2014resembled the same ones seen in #B117 & #B1351.

Dr. Li couldn't believe what they found. "I was shocked," he says. "When I saw the virus sequences, I knew that we were dealing with something completely different and potentially very important." pic.twitter.com/HT3Yt6djFd
It was only when it became obvious that measures in Kent were failing that Public Health England realised the outbreak was being driven by a new variant.”
DIFFERENCE A VARIANT CAN MAKE: Early in the Oxford-AstraZeneca\u2019s South Africa \U0001f1ff\U0001f1e6 trial, before #B1351 variant became dominant, the AZ vaccine had a great efficacy of 75% risk reduction of #COVID19 after a single dose! But all that disappeared once B1351 variant showed up... \U0001f9f5 pic.twitter.com/LcVcV2aVzE

\u26a0\ufe0fSURGING #B117 WITHIN US\u2014growing 7% per day, doubling every 9.8 days nationally, & expected to become dominant by March 23rd. It is surging fastest in Florida\u2014doubling every 9.1 days. Scientists are extremely worried: 35-45% more transmissible.\U0001f9f5#COVID19 https://t.co/T3GV8anzYz pic.twitter.com/RFyifNq4QS

\u26a0\ufe0fConcerning\u2014new data shows the more contagious #B117 variant is growing so quickly in Florida\u2014now almost 10% of all #COVID19 case. California only ~2 weeks behind. Surge of #B117 may yield April wave if vaccine rollout slow. \U0001f9f5

It\u2019s all possible if we aim for full suppression, and not just half-ass mitigation. We can do this. pic.twitter.com/tY4wBdPlac

2) Now, the Oregon Health Authority says that at least 74 people associated with the church have tested positive for the coronavirus — one of the state’s largest workplace outbreaks.
3) “In a statement, the church’s leaders attributed the outbreak to a recent rise in covid-19 cases in Marion County, Ore.
Murray said the church, which has held in-person services throughout the pandemic, intends to continue with in-person ceremonies on Sunday.
4) Who saw this coming? Countless scientists. If only airborne-denialists didn’t muzzle the airborne aerosols science.
\u26a0\ufe0fAIRBORNE >6 FEET / 2 METERS! The CDC finally acknowledged #SARSCoV2 has major transmission via airborne aerosols beyond 6 feet / 2 meters, not just close contact.

2) Here is what is really going to happen... most countries are having a gentle case decline with R(e) currently around 0.9. But this is deceiving. The #B117 is still relatively rare so far, so the R is being influenced mostly by the old common variant. But not for long...

3) Here is what is going to happen... currently R is ~0.9 in many places, but with the more infectious #B117, the R will jump 50% approximately. And it is inevitable (all CDC and Danish models say this) that B117 will take over as the reigning dominant variant soon...

4) and when that happens, what worked before to keep the pandemic contained at R of 0.9 will no longer work. Here is the model for Alberta, 🇨🇦 by @GosiaGasperoPhD. The B117 dotted red line will soon dominate and drive a new surge in latter half of March and April.

5) And Denmark 🇩🇰 CDC has found the same thing. I GQR works now for keeping R around 0.9 or even 0.8, will absolutely not work anymore once #B117 variant takes over. Forget about it. We will be hit hard. But there is a way—if we suppress R to 0.7 or less.

2) this guy was just arrested.

3) We cannot have a repeat of the fascism from WW2. This is @Schwarzenegger’s speech was so powerful.
This speech will go down as one of the greatest speeches. @Schwarzenegger is right\u2014Jan 6th 2021 was our Kristallnacht. Austria \U0001f1e6\U0001f1f9 tried to resist Hilter takeover for years but succumbed because Hitler\u2019s lies went unchallenged. We must #impeach now. pic.twitter.com/gOChiGLuHK

4) My wife @andreafeigl1’s 🇦🇹 great grandfather secretly fought Hilter’s Nazi regime & smuggled many Jews to safety as an aircraft engineer. He was thrown into a concentration camp, and escaped.
She knows a few things about Nazi history—Jan 6th was downright fascist. Read 👇
Some saw clearly what MAGAism is - pure fascism - in 2016.

More see it 2day
Some saw this playbook b4: WW2
Americans r too unaware of history since it didn't happen on home soil
But we MUST heed these lessons, lest it b 2 late 4 democracy & consequences are unfathomable

5) So this cover is from a semi-tabloid magazine in Germany, according to @andreafeigl1. But even so, how did such a magazine still get it so damn right?! Maybe Germany 🇩🇪 has seen this kinda fascism before...

2) That said, the new UK mutated strain is a more transmissible (contagious) variant. Keep transmissibility and illness severity separate. They are two different things. Don’t get them confused.
3) The new UK variant severity study is included in today’s WHO report, to be released soon this afternoon according to WHO sources. Waiting for it to drop. I’ll keep folks posted on the details.
4) Update: here is UK Technical report on #SARSCoV2 variant of concern (B.1.1.7) in 🇬🇧 with prelim findings from their case-control study of no increased severity for the new variant that I reported yesterday.
5) Also keep in a mind that a virus that spreads faster (more contagious) yields much worse total outcomes than a virus that is just merely more severe.
All things equal, a new mutated variant that is more contagious & no more severe is worse. And that is what we now have.
Why a SARS-CoV-2 variant that's 50% more transmissible would in general be a much bigger problem than a variant that's 50% more deadly. A short thread... 1/

In some cases, almost 100% of the light energy can be converted to the second harmonic frequency. These cases typically involve intense pulsed laser beams passing through large crystals, and careful alignment to obtain phase matching.
