📍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.

Reminder—Trump had expressed executing people on many occasions while President, according to his own Attorney General. Now the Supreme Court has green lit any official act with full presidential immunity. Germany did the same in 1933. It turned out great.
2) If we ignore history, we are bound to repeat it. How Germany became Nazi Germany in 1933….
3) And the U.S. military will become Trump’s official personal army.

American Democracy is dead. Long Live the King. The King can now “assassinate you, officially”.

2) Laws aren’t really laws anymore to the President of the United States. Who do you want as president now?
3) American democracy had a great 240-year run. Too bad it’s now sorta over after today’s SCOTUS ruling.

📍 The New York Times Is Failing Its Readers Badly on Covid

📌“Example of ‘science opinion’ run amok in the [NY Times] is a piece… by Zeynep Tufekci, a commentator with no training in biological science or epidemiology… ➡️Tufekci plays into the hands of the anti-science politicians who now seek vengeance on the flimsiest of grounds.”

By GREGG GONSALVES and JOHN P. MOORE
thenation.com/article/societ…Image

2) “Tufekci also adds to the ongoing pile-on about whether the directive to maintain a distance of six feet from others was needed. Although the precise distance was indeed somewhat arbitrary, there was no possibility of obtaining hard data in the relevant time frame. The six-foot distance was a reasonable assumption based on public health history, and the practice of social distancing for other respiratory pathogens, particularly those spread by droplets. It was also adopted in multiple other countries, for the same reasons.”
3) “The problem here isn’t that Tufekci is questioning the evidentiary basis of the six-foot rule—science and public health cannot progress if we don’t evaluate the results of our work. But that progress is more effective when grounded in good-faith inquiry, rather than the kinds of attacks Tufekci levels against government scientists for doing their best in desperate circumstances. This only serves to bolster the forces who seek to destroy the US public health infrastructure, not make it better.

Tufekci also leaves the impression that she alone realized SARS-CoV-2 was airborne early on. In fact, the debate about transmission was fast and furious within the scientific community at that time”

⚠️Whooping cough has smashed all records in UK🇬🇧 with barely any serious govt actions. These are NEW CASES PER WEEK, not cumulative. Each week smashing previous. Other countries rising too amid anti-vax. Pertussis is also airborne!

Graph @1goodtern

2) And yes it’s airborne damnit. CDC says so.

cdc.gov/pertussis/hcp/…

3) Whooping cough is also extremely contagious. For up to 3 weeks. With UK govt advising staying home for 3 full weeks if no antibiotic treatment. How many people being told that and doing that?

⚠️SURGING COVID cases & hospitalizations in Madrid, Spain🇪🇸—hospitalizations for COVID has now exceeded also 2022-2023. This is the globally surging KP3 variant (US too)—it is highly evasive against past immunity—you’re not immune. Take preventive action.
comunidad.madrid/sites/default/…

2) New York City’s COVID cases are also increasing, as noted by @emmagf. June is not normal cold and flu season at all. This shows that this KP3 surging despite non-flu season means it’s a troublemaker. Image
@emmagf 3) Hawaii’s ERs also have gotten slammed hard by an off-season COVID surge. This isn’t normal at all for June. This is why we need to be on alert. Image

📍Breaking—MASK BAN PASSED AGAIN—North Carolina Republicans have again voted to pass a new ban on mask wearing. Only a weak partial medical exemption added for PUBLIC areas—but, on private properties, like at grocery stores or at a workplace, the bill now says people can still be “REQUIRED TO REMOVE MASKS” if demanded by employer or owner (your health be damned). But, thank goodness Halloween masks will still be allowed.
motherjones.com/politics/2024/…Image
2) “Many healthcare professionals have expressed concerns that their patients would not be able to stay safe against the spread of Covid-19 and other infectious diseases.” Image
3) the scary thing is that “The bill, which was drafted in response to people wearing masks at Pro-Palestinian protests, can be passed by the General Assembly **even if Democratic Governor Roy Cooper vetoes** it through an override.”
