I’m concerned about the new #BA2 sub variant of #Omicron. In the left panel, you see it is surging (light green) to almost half of all Danish 🇩🇰 #Omicron cases—surpassing the old Omicron BA1 variant by a lot. Either it’s much faster transmission or it evades immunity even more.👇 ImageImage
2) Elsewhere in 🇬🇧, while still early, #BA2 Omicron subvariant is doubling now every ~4 days right now… while every 4 days is slower than original #Omicron displacing delta every 1.5-3 days, BA2 displacing Omicron BA1 is a really bad sign. Image
3) Denmark, #BA2 passed BA1 on Jan 12th it seems (we are only knowing now due to sequencing delays). Image
4) here again is #BA2 in the UK 🇬🇧 - early but fast. Image
5) here is Germany’s rise of BA2 as well. Early but looking exponential too.
6) here is BA2 in Netherlands 🇳🇱— already at 5%. HT @LongDesertTrain Image
7) UPDATE— we now have an estimate of BA2 transmission growth advantage over vanilla #Omicron BA1. It’s not good… see thread 🧵 below… it’s approximately *DOUBLE* of omicron. Unclear if contagiousness or if immunity evasiveness. Either way it’s growing faster… 👇
8) the other bad news on #BA2 is that our old friend, S-Gene dropout shortcut (PCR) test, cannot identify the BA2 sub variant easily—while BA1 #Omicron is easily found these days with SGTF. This might make deciphering BA2 and Delta & other strains harder. github.com/cov-lineages/p… Image
9) Danish scientists have warned that BA2 is trouble. We should heed their warning. I want this pandemic over but wishing it away doesn’t solve anything. Only through collective action can we end it.
10) there is no proof newer variants will necessarily become milder & endemic as if by magic. That’s bullshit wishful thinking. I trust Professor Gregory on this — don’t listen to TV pundits who are paid to sell you “reopen everyone and let it rip” propaganda.
11) do no listen to folks who claim endemic means normality and the disappearance of COVID worries. They don’t explain to you what endemic really means. There are really bad endemic outcomes too. 👇
12) Virus researcher & chief physician of Denmark 🇩🇰’s CDC @SSI_dk says you can get **reinfected with #BA2 sub-variant** of #Omicron after being infected with Omicron BA.1. ➡️ This is why we shouldn’t risk COVID or chase mass infection. nyheder.tv2.dk/2022-01-21-ny-… Image
13) UPDATE— Denmark 🇩🇰’s #BA2 Omicron subvariant has now fully taken over — dominant with 65% of all sequences #Omicron… Germany and Netherlands and UK not far behind. US has a handful of cases but likely rise soon too.
14) is COVID slowing in Denmark 🇩🇰? Absolutely not. #COVID19 continues to spike along with deaths. ImageImage
15) there are naysayers who point to ICUs dropping. But that’s misleading — because instead of hospital ICUs, Denmark relies on long term care nursing home facilities - which deaths are going up. Hence you need to look at deaths not partial ICU numbers in 🇩🇰
16) here is a better graph showing deaths surging in Denmark 🇩🇰 — pretty clear #Omicron isn’t “mild”.

ourworldindata.org/coronavirus-da… Image
17) UPDATE— Denmark’s CDC says BA2 subvariant of #Omicron is about ~1.5 times more contagious than BA1 (original Omicron). This makes it much higher than prior estimates and could “extend” the Omicron wave into February, says Denmark 🇩🇰 officials. ssi.dk/-/media/arkiv/… Image
18) not good - Denmark (where BA2 is most common) is seeing really bad hospitalization surges. Many even with boosters. BA2 could be quite evasive against past immunity I’m thinking as well as more contagious.

⚠️BREAKING—ICU Hospitalized human bird flu case in Canada now officially confirmed as H5N1. Worse, it is the same 2.3.4.4b virus clade (variant group) as the one found in BC🇨🇦 poultry and in Washington state🇺🇸! The hospitalized teenager (with no pre existing conditions) had no animal contact, does not live on farm, had “deterioration quite rapid” and now critical in ICU with ARDS. Canada officials says infectious period is 2 days **prior to symptoms** (ie asymptomatic transmission) and infectious up to 10 days.Image
2) Public Health Agency of Canada's National Microbiology Laboratory (NML) in Winnipeg confirmed that the individual has avian influenza H5N1

My god—Google Search for “what is a tariff” sudden spikes the DAY AFTER ELECTION DAY. 🤦🏻‍♂️ Image
2) many folks simply don’t understand what a tariff is — unless you explain it several times to them with analogies. Even then, it’s hard for many to grasp. Eg 👇
3) Ah shit… it’s now gotten worse. Why do so many people do their hw late??,

Plastic cookware should not be used. Period. Especially BLACK PLASTIC cookware, that often mixes in toxic recycled electronic waste materials. DISPOSE OF ALL PLASTIC COOKWARE, especially if black colored plastic ones. Pass it on to your family.

2) Because optical sensors in recycling facilities can’t detect them, black-colored plastics are largely rejected from domestic-waste streams, resulting in a shortage of black base material for recycled plastic. So the demand for black plastic appears to be met “in no insignificant part” via recycled e-waste, according to Turner’s research. TV and computer casings, like the majority of the world’s plastic waste, tend to be recycled in informal waste economies with few regulations and end up remolded into consumer products, including ones, such as spatulas and slotted spoons, that come into contact with food.
3) You simply do not want flame retardants anywhere near your stir-fry. Flame retardants are typically not bound to the polymers to which they are added, making them a particular flight risk: They dislodge easily and make their way into the surrounding environment. And, indeed, another paper from 2018 found that flame retardants in black kitchen utensils readily migrate into hot cooking oil. The health concerns associated with those chemicals are well established: Some flame retardants are endocrine disruptors, which can interfere with the body’s hormonal system, and scientific literature suggests that they may be associated with a range of ailments, including thyroid disease, diabetes, and cancer. People with the highest blood levels of PBDEs, a class of flame retardants found in black plastic, had about a 300 percent increase in their risk of dying from cancer compared with people who had the lowest levels, according to a study released this year. In a separate study, published in a peer-reviewed journal this month, researchers from the advocacy group Toxic-Free Future and from Vrije Universiteit Amsterdam found that, out of all of the consumer products they tested, kitchen utensils had some of the highest levels of flame retardants.

⚠️MASK MANDATE RETURNING TO ALL NIH PATIENT CLINICS—Effective November 4, 2024, masking will be required in all patient care & waiting rooms. Furthermore, testing for COVID, flu A, flu B, and RSV will be required for all inpatients & rooming-in visitors.

2) This means wearing a mask will be REQUIRED in all patient care areas, including waiting rooms. ➡️This change is due to an anticipated increase in COVID-19 and other respiratory virus activity in the community. 😷
3) I think people should stock up on COVID tests again. The Cheapest COVID test on the U.S. market is now as low as $1.50 with special promo code “COV20”… expiring Jan or March 2025.
