📍OUTBREAK OF #B117 AT SEVEN SCHOOLS—sudden outbreak of #COVID19 cases at a British Columbia 🇨🇦—all elementary and middle schools. Genetic sequencing shows #b117 in early cases linked to outbreak. Classes quarantined. All the schools still remain open. 🧵 cbc.ca/news/canada/br… ImageImage
2) British Columbia 🇨🇦 teachers are now incredibly worried by the latest sudden 7 school outbreaks, and demanding decisive actions.
3) British Columbia is having a major increase in transmission — and has the highest R in Canada 🇨🇦 currently.
4) A statement from the Surrey School District to parents says the strain detected at two of the schools was connected to positive cases dating back to Jan. 26 because testing for the variants takes longer than the standard COVID-19 test.
5) The three-week delay is too long, said Sarah Otto, a professor in evolutionary biology at UBC.

"We expect it to double every eight to 10 days, and so for every eight- to 10-day delay there's potentially twice as many other people who have caught it and not know about it.''
6) The Fraser Health statement says it is working to identify any more connected variant:

"The variant strain can transmit more quickly and easily but does not seem to cause more severe illness”

➡️ this is incorrect. #B117 is said by 🇬🇧 experts to increase severity as well.
7) Apparently, masks weren’t mandated at every school, according to @bctf.

Epic fail.
8) Recently, UK says #B117 variant can be 30-70% more severe than old common strains.
9) This BC follows the heels of two other notable school outbreaks in Austria and Denmark and kids surge in Israel.
10) The Danish multi school outbreak was also #B117 related.
11) As was the Italian village #B117 outbreak in which 60% of the infected were children.
12) This divergence in children also seen in the UK, despite general lockdown. After winter break, positivity in 5-9 year olds higher vs adults after primary partially schools reopening. This wasn’t seen last year at all.
13) These can no longer be dismissed as isolated stories. We know school reopening lead to rise in cases. We cannot delude ourselves on this!
14) Meanwhile, BC 🇨🇦 leaders downplay everything even as #B117 spreads and BC’s R is increasing, says @PennyDaflos.

bc.ctvnews.ca/b-c-health-off…
15) BC schools are also atrociously **SCREWING SHUT WINDOWS** to prevent teachers from opening them for fresh air!!! Can’t make this insanity up—all while in middle of outbreak. cbc.ca/news/canada/br…
16) But that^ is exact opposite of what we need to do to stop school transmissions. We need more ventilation and air cleanings. Ventilation is the easiest and best. Air disinfection next best. See thread 🧵
17) Ventilation and air disinfection is just so critical for schools and any crowded places.
18) Another datapoint of pediatric case surge ever since schools reopened without mitigation in Iowa.
19) Another reminder we have known the coronavirus is airborne—long distance aerosol travel and aerosol infection means we need to take serious transmission in schools and prevent indoor dining.
20) And I agree with anxious and worried @bctf teachers... they need widespread rapid testing to stay ahead of outbreak before epidemics grow to multiple classrooms, grade levels, and schools.
21) Meanwhile.... another multi-school outbreak in Toronto that seems similar to BC #B117 school outbreak.
22) And the clearest evidence of school #COVID19 transmission of teachers and kids comes from Quebec... the evidence on schools is irrefutable.

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.
