Let this sink in—

The more contagious #P1 variant from Brazil has now invaded N America—British Columbia🇨🇦 has a sudden cluster of 215+ new #P1 cases sequenced by one Vancouver lab.

#P1 is more contagious, has reinfection risk and possibly more severe.🧵
2) 215 identified by one lab in Vancouver — and not all even included in public reports by BC health Dept yet (they are much slower reporting than CTV news)

BC 🇨🇦 has added 20-30 daily #P1 cases per day for the last 4 days (again not including all the #P1 above)
3) And are these new #P1 cases due to international travel or were they local transmission?

The BC health Dept report few days ago said the initial 84 cases were all community transmission!! Zero international travel. This is a bad sign — so many at once and no travel. Image
4) One Brazil @obscovid19br study puts #P1 transmission at 2.5x faster than old common strain. This 150% increase is much faster than even #B117 if it holds up.
5) Meanwhile, another UK group at MRC Imperial puts #P1 at 2x (100% increase) more transmissible than older common strains— but with even larger reinfection potential.

Keep in mind #b117 from UK is only 40-60% faster than old common. Both studies imply #P1 is faster than B117.
6) And is there early data suggesting #P1 is more severe?

“an increase in CFR for almost all age groups observed. All groups above 20 years of age showed significant increases in CFR (Case Fatality Ratio)”

when comparing February 2021 vs January 2021...
medrxiv.org/content/10.110…
7) Notably:

📌Patients aged 20-29 years experienced a tripling of their CFR

📌aged 30-39, 40-49, 50-59 experienced ~CFR doubling

➡️”Individuals between 20-29 years of age in February 2021 had an over 3-fold higher risk of death compared to January 2021.” Image
8) “findings suggest significant increases in CFR in young and middle-aged adults after identification of a novel SARS-CoV-2 strain circulating in Brazil, and this should raise public health alarms” ⚠️
9) British Columbia’s recent #P1 spike isn’t the first outside Brazil 🇧🇷. As alluded to in the video (top post), there are surges also in neighboring Paraguay and Uruguay— where ICU hospital beds are now maxed out. see thread 🧵 below.
10) We need to all prevent #P1 from causing more clusters and hotspots around the world. Because we cannot repeat the crisis in Brazil 🇧🇷 right now. See detailed #P1 thread below.
11) Head scratching frustrating — I don’t know why BC health chief keeps dismissing the variants of concern (B117 P1 and B1351) as not different than older strains. That is clearly false (see above) and well known for months. @CDCofBC 🇨🇦 needs to wake up.
12) UPDATE—after some weekend pressure, BC 🇨🇦 health chief Bonnie Henry finally admits there is a serious issue with #P1 variant - now announced discovery of 270 cases in BC! And she finally admits P1 is a problem. BC now on short circuit breaker.
13) Bad update— another 100 new cases of #P1 variant logged in BC 🇨🇦 today. This is exponential.

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.

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.
