What I have learned since being unwell myself has destroyed any faith I had in my profession’s leaders. I used to think that deep down most senior clinicians acted because they had the best interests of the patient, their colleagues & society at heart. That illusion is gone. 1/n
Be it the treatment of those with #MECFS #LongCovid #Fibromyalgia #POTS #MCAS #EDS #HSD #PansPandas #Lyme #FQtoxicity #vaccineinjuries & other so-called invisible illnesses; 2/n
the refusal of senior medics to stand up & protect colleagues, the public & schoolchildren from airborne spread of #SARSCoV2 as they are too afraid to displease those in the ivory towers of infection control, @UKHSA & @NHSE management & @UKgovcomms; 3/n

This is not how a healthservice should run.

Threat of contracting Covid will deter vulnerable patients from seeking medical care. Those who decide to take this risk, face risk of death or permanent disability.

How is this in any way legally or morally acceptable? @sajidjavid
Patients deserve to be treated & cared for in a safe environment.

NHS staff deserve to go to work without fear of dying or becoming permanently disabled.

Hospitals MUST start to install air filtration systems #hepa. It’s time to make the air safe & invest in #cleanair

Many thanks to @ProfEmer for his presentation on ‘Health and safety: lessons learnt from the pandemic” at todays BMA Medical managers conference 2022.

I would like to share with you some of his slides & key points discussed. 🧵
From past experience (2002-3 SARS and 2012 MERS) UK government @Conservatives should have been better prepared for the SARS CoV-2 pandemic.
Health and safety research in *2008* for @H_S_E showed surgical masks (FRSM) failed to protect against an airborne transmitted pathogen. Image

Odotan jo nyt millainen farssi syntyy kun @vapaavuori@helsinki⁩ & valitut #Covid19🦠-taktiikat tulevat selvittelyyn : 🍿

”Jan Vapaavuori pakoili tökerösti vastuuta – yksi ristiriita meriselityksessä paljastaa totuuden armottomasta kulissipelistä”…
Aikooko @kokoomus yhä ajatella #Vapaavuori nostoa presidenttikisaan, kun maine on kahden valtavan virheen pilaama:
1. #Olympiakomitea ja lähentelyjen salliminen osaksi sen toimintaa
2. vielä täysin käsittelemätön, käsittämätön Helsingin kaupungin #GBD-#SARSCoV2-linjaukset 2/
Vapaavuoren luotsikaudella. On ollut jo kauan 100% selvää, että Vapaavuoren anderstegnell-tyylinen käsitys siitä, miten virusta levittämällä luotiin mm. maskittomuudella #LaumaSuojaa, se ei toimi #SARSCoV2-viruksen kohdalla.

I want to share an analogy & call to #Hospitals to #ProtectHCWs. 2+ years yet hospitals leave workers open to PREVENTABLE death & disability. They need to held to task & REQUIRED to properly & fully protect their workers. Please join me & share this. #HCWs #Covid #LongCovid (1/3)
#HCWs DESERVE government protections, as do patients! It is unethical for them to continue to skirt proper air filtration & personal protective equipment MINIMUMS. @OSHA_DOL are you listening? #OSHA #P100 #respirators #Ventilate #HEPA #LongCovid #CovidIsNotOver #MaskUp (2/3)
Providing P100 respirators, increasing proper indoor air filtration, & testing workers regularly will help attract & retain staff. In addition to it being the RIGHT THING TO DO! Questions? Contact me #DoTheRightThing #LegislateProtection #ProtectHCWs #Nurses #ProtectRNs (3/3)

📣 What today's announcement means to us? 🧵

This account gives an anonymous voice to Clinically Vulnerable people in our support group on Facebook.

Threats now to:
Lives, jobs, freedoms + safe access to schooling & healthcare.

Join us for support 👇…
This thread aims to share our members thoughts, each struggling with the broad and significant impacts of the announcement to be made today by Boris Johnson in the HoC.

2/ Freedom for some is being granted at the expense of freedom
"End of any freedom with covid has now been stolen for the vulnerable."

"The mental health of my children going to school will now spiral downwards uncontrollably."

3/ Our death sentence from Covid has now been set.

Ultimate Freedom Day is forcing the most vulnerable into impossible situations.

How can we #StaySafe?
No testing. No isolating.

How can we judge our risks?
No ONS data, no government data.

How can we even access healthcare?
No masks.

With no masks and no isolating how can forced return to F2F work be viable in these circumstances?
We are choosing between #LivesAndLivelihoods

How can we send our children to school safely?
We are choosing between #educationANDlives

Why is the answer ONLY more vaccines?
Severely immunosuppressed may not have made a response to 4.

Where is the real world evidence this will make a difference?
No other country is offering 5 doses.

What about the other CV / CEV?
Vaccines waning.

1/ So tired of smug garbage thought pieces in pubs like @TheAtlantic trivializing #COVID mass death & #HealthInequity

Thousands dying daily & cont'd health inequity means we haven't done what's needed to stop mitigations or "open" things that aren't even closed #UrgencyOfEquity
2/ Pieces like this endorse society brushing past those who remain at most risk from #COVID to move to a past inequitable "normal," while making a passing, half-hearted "that's tragic" comment about continued COVID health inequities & suffering.…
3/ Interesting that the author expressed concern that "Many white-collar workers still haven’t returned to the office" but failed to mention healthcare, retail, or factory workers. #UrgencyOfEquity #COVID

2/ Son is due to start year six on Monday at a state primary school in Brisbane. We've had a close look at the QLD govt’s Back to School plan and talked to the principal about how it will be implemented.…
3/ It’s clear the QLD govt’s Back to School plan is grossly deficient and exposes kids to much greater risk of COVID than it should.

The plan has 7 major failings. . .

#Arlington #COVID19 #Cases

😡: Almost no students who are exposed are being told directly of exposures or quarantined.

We encourage parents w/COVID+ kids to DIY your own reporting to parents and families where you can; assume APS isn't going to notify exposed. It's up to you. Image
#Arlington #COVID19 #Cases

The worst school, with >13% of its students catching COVID in Jan, is #Montessori Public School.

MPSA was found to be one of the worst schools for ventilation + parents reported a lack of implementation for outdoor lunch in Jan. for some classes. ImageImage
#Arlington #COVID19 #Cases

So far, YTD, two dozen Arlington public schools have had more than 10% of their student body test positive for COVID-19.

In such an environment, removing masks when community transmission is so high seems like the ultimate folly. Image

The air cleaner purchased by @nseducation for schools has a Clean Air Delivery Rate almost HALF of a common retail unit and may create secondary products by reacting with gas phase contaminants in a poorly ventilated room using photocatalytic oxidation #nspoli /1 Guardian Beyond Air F159E: ...
As seen in the photo, it's not running on its highest setting. For #ventilationequity in non-mechanically ventilated classrooms, should be a min 15 CFM per person, or 375 CADR for 25 people, AND at an acceptable noise level. How many per classroom? #DoTheMath! /2
Don't get me wrong, any filtration is better than nothing! But it's a mere band-aid over a gaping wound.
A DIY $120 #corsirosenthalbox will beat the air cleaners purchased by @nseducation AND can be used in STEM lessons! See /3 Screen capture of web site

This has everything to do with $$ Improved ventilation has been spoken about in #Ontario almost from the beginning. @fordnation didn't want to spend the money on #ontarioschools, so they gambled that #COVID could be managed without having to retrofit schools or add #HEPA filters
COVID being #Airborne has been known for over a year, and yet they didn't provide essential PPE to you and your teachers.Testing could have kept you in school, but they chose not to implement a regimented testing system. Any kid born in 2004 who will be eligible to #vote
remember that this govt gambled away your highschool years, your rites of passages, your education, your emotional well-being and your physical well-being because they didn't think you were worth protecting. Show them your worth on June 2nd, 2022. #VoteFordOut2022

'Hidden hazards of SARS-CoV-2 transmission in
hospitals: A systematic review'

Very timely, given #Omicron

@mjb302 @andymoz78 @microlabdoc @LawtonTri
I think you'll like this

'SARS-CoV-2 can be frequently detected in hospital air since 1:6 air samples were contaminated with SARS2. Airborne SARS2 RNA was detected throughout the hospital, regularly beyond the social distance of 2m from patients even extending up to 7.6m away from the nearest patients.'
'The nature of air contamination revealed the existence of patient-generated, size-fractionated, & infectious aerosols & that...only fine [<5microns] aerosols contained viable SARS-CoV-2.' @drkristenkc @Don_Milton

1/ #SARSCoV2 leviää #Aerosol viruspartikkelien avulla joita uloshengittää tartunnansaanut. Haluat välttää näiden partikkeleiden sisäänhengitystä (🦠partikkelimäärä⬇️). #Vuosikymmenien_tutkimus kertoo seuraavien keinojen laskevan sisäänhengittämiesi aerosolpartikkeleiden määrää:
2/ #Maskit: mitä korkeampi laatu ja mitä parempi istuvuus kasvoilla, sitä vähemmän sisäänhengität itse aerosolpartikkeleita joita tartunnansaanut uloshengittää yhteiseen hengitysilmaanne. Tämä ei ole rakettitiedettä.

Aerosol voi ilmaleijailla tunteja.…
3/ #Ilmastointi: Mitä tehokkaampi ilmastointi ja #Tuuletus, sitä vähemmän ilmassa on aerosolpartikkeleita joita tartunnansaanut/-neet hengittävät yhteiseen, jaettuun sisäilmaanne. Näin sisäänhengität viruspartikkeleita itse vähemmän. Tämä ei ole rakettitiedettä, vaan simppeliä.

Nadhim Zahawi has written to School leaders.

Focus = attendance

This is particularly concerning attendance targets are already driving many headteachers to threaten vulnerable households with fines and prosecutions.

He emphasises the fact that schools must not use the following mitigations: bubbles or isolation of contacts.

Whilst insisting on the need to improve attendance "maximising school attendance a top priority" in a #Pandemic.

Next, something we have been pushing for (if only it wasn't in that same paragraph demanding attendance). An acceptance that vulnerable children have been impacted more than others. * although no mention of children in vulnerable households.

GET HEPA FILTERS—Real-world data show that filters clean COVID-causing virus from air. An inexpensive portable #HEPA filter efficiently screened #SARSCoV2 and other disease-causing organisms from hospital air. #COVIDisAirborne #COVID19…
2) “This study suggests that HEPA air cleaners, which remain little-used in Canadian hospitals, are a cheap and easy way to reduce risk from airborne pathogens,” says @DFisman, an epidemiologist at the University of Toronto, Canada, who was not involved in the research.
3) And the scientists found that the filters don’t only protect against SARS-CoV-2. When the filters were switched off, the air contained detectable amounts of other pathogens that cause infections, such as Staphylococcus aureus, Escherichia coli and Streptococcus pyogenes.

Mr Williamson, it’s becoming increasingly difficult to contain my horror at #DfE plans for the return to 🏴󠁧󠁢󠁥󠁮󠁧󠁿schools this week.

Such insincere tweets are deeply offensive to anyone who’s been personally affected by serious acute #COVID, #LongCovid or been bereaved by it.
Suggesting schools “get back to a greater sense of normality…” during a pandemic of an #airborne 🦠reveals a marked lack of scientific understanding of the issues & is an utterly disingenuous way to present the situation to parents & children who deserve far better.
And to those of us caring for patients to w/ #COVID19 whilst simultaneously trying to tackle the ever growing mountain of non-#COVID care (STILL in sub-optimal #PPE) it is a huge slap in the face.

Good afternoon @RishiSunak & @BorisJohnson

Claims that “we can’t control the spread of the virus.The virus is doing what’s doing….”, that we must learn to “live w/ #COVID” & exert “personal responsibility” are incorrect, disingenuous & dangerous!
@BBCNewsnight @simakotecha
What you actually mean is that YOU (& your government) have deliberately CHOSEN to prioritise the ECONOMY over the HEALTH & WELLBEING of the British ppl…..but are dishonestly & patronisingly pretending there is no other option?

@10DowningStreet @sajidjavid @Conservatives

W/ easy access to scientists & public health experts, anyone used to researching, looking for & assessing evidence, can find plentiful, accessible information on how to reduce #coronavirus transmission!

For highly educated ppl like yourselves, it would be an absolute doddle!

"6 Questions To Ask Your Colorado School About COVID And The Air In Your Child’s Classroom"

Great, well-researched & hyperlinked article in @CPRNews by @CPRBrundin

These are not rhetorical questions -- pls contact your #school district!
🧵 below (1/x)…
2/ Also don't miss the link to answers from 25 #Colorado school district on their COVID response. Brilliant & critical public health info!

Using this info you can follow-up based on the questions @CPRBrundin provides!……
3/ #AskYourDistrict:
1. How is the air in your child’s classroom being filtered and ventilated?

- Improve to MERV 13 filters, minimum of 5 ACH air exchange, and open outdoor air dampers
- Don't forget the long-term benefits
- Way to go @ESDk12 for using federal $ on air upgrades

I’m right behind you @Sandyboots2020👏

Just imagine what school improvements £37bn would’ve bought @BorisJohnson ?

Maybe there isn’t a #Tory MP or donor w/ an interest in #ventilation systems, #HEPA filters, CO2 monitors etc?

Is it just not lucrative enough @Conservatives?
I’m surprised none of the VIP #PPE contract beneficiaries didn’t spot an opportunity to make some extra cash supplying schools with FRSM😷s knowing #COVIDisAirborne ?

For those foolishly continuing to block out the truth of #COVID19UK, this👇🏼isn’t what “recovery” looks like.
The ONLY CONCLUSION one can draw from #DfE advice is that UNMITIGATED #coronavirus TRANSMISSION in 🏴󠁧󠁢󠁥󠁮󠁧󠁿/🇬🇧schools IS THE PLAN for the 21/22 academic year!

The HUMAN collateral damage’s been “baked in”- lives lost, chronic debilitating illness, orphaned children…ALL AVOIDABLE.

Great work on a new report by @JHSPH_CHS via @polsiewski et al:…

Listen to the wide collections of experts -- improve ventilation schedules & add room #HEPA filters to back-to-school safety checklist.
Highlights of exec summary recommendations in 🧵 below.
1. School administrators and decision makers should improve #school #ventilation now by bringing in as much outdoor air as the heating, ventilation, and air conditioning (HVAC) system will safely allow and upgrading filtration.
2. School administrators and decision makers should purchase #HEPA air #filtration units to be placed in classrooms and common occupied spaces.

💡How to save kids lives & prevent hospitalizations with $55–make your own Corsi Box!! Seriously—if you don’t have a HEPA filter, then do this!👇

📌A motto in environmental health—THE SOLUTION TO (#coronavirus) POLLUTION IS DILUTION (#ventilation) & FILTRATION (#HEPA /#CorsiBox)
2) Technically this is a “Corsi Box” with 5-6 MERV-13+ filters arranged in a cube like this below 👇… I’ve been recommending this for over 6 months! Air disinfection is critical!
3) we know for certain that air disinfection (with either a portal HEPA filter or a Corsi box 📦 comprised of MERV13 filters in cube) works. Studies support the benefits of HEPA filter. The key is to get them into schools — if school won’t buy it—then just buy & donate to teacher
