Paul H's (failed) quest for washable N95 and more
@Washable95
Masking until the HVAC installations catch up with the airborne-transmission science. I love my nose-wire boosted KN95s

@1goodtern Handwashing compliance to prevent airborne transmission though ???? /s

I don't have Long Covid, and have never had Covid. But I advocate for those who do....
Lazarus Long@LazarusLong13
I'm curious - any other LongHauler advocates like myself who do NOT have LongCovid? (But, my advocacy is born out of self-interest/survival, because I recognize I am advocating also for a possible future me who could have LongCovid.)

@NukitToBeSure #teamDroplets: but but but washing your hands also keeps you safe from food borne pathogens too!!!!!

Huh, it's starting to look like 222nm would be very effective for open buffets, deli counters, and food prep areas🤔

Now, the UK Covid Inquiry @covidinquiryuk was supposedly meant to uncover how those early decisions were made.
CATA say it has struggled to do so because key emails, advice and records about how expert warnings were delivered were not fully disclosed.

@Victoriantaddeo @1goodtern sciencedirect.com/science/articl… .. doctors neckties their own disease vectors
English
@1goodtern Most still don’t wash their hands in between seeing patients. Doctors are not that smart.

@1goodtern Guardian staff know it’s Covid effects at the cause of this, they just are under instruction to avoid it as much as possible. huffpost.com/entry/analysis… informs that it’s about maintaining access to government ministers.
English
@BehindWards I would think that’d eclipsed by lost tax revenue and increased healthcare costs of those that could’ve avoided long COVID if the air were cleaned, etc
English
Serious question: has anyone estimated the cost to the UK economy of COVID “hygiene theatre” in retail?
Staff disinfecting trolleys, wiping surfaces, constant mopping- actions that don’t prevent aerosol spread.
Labour, chemicals, damaged goods, slower throughput. Any research?

13/There is no universal perfect air purifier.
The best choice always depends on context and criteria.
My own criteria are: space,noise, watts, CADR and $ cost.
Aesthetics matter much less to me, and I don’t require lab certification because I test machines in my own chamber.

1/ If I hear one more public official call indoor air filters a "band-aid," I'm going to explode! It's so logical, yet so readily dismissed. Filtering indoor air should be as standard as filtering water. Full stop. 🧵

Other than the classroom, could the crowded ED waiting room be the highest risk shared space?
Suggest sitting in the clean air flow coming from the HEPA filter if there is one, and ask for an N95!
“The ED waiting room is a site for the potential spread of airborne infections, such as SARS-CoV-2, influenza, measles, and high-consequence pathogens, as patients and their families may wait for many hours in this shared space. Failure of diagnosis and triage of potentially lethal infectious agents is a recurring problem worldwide. Increased mitigations for the waiting room area can help reduce these risks.”

Health workers get exposed to viruses much more than others because of their work. It's not hard to understand why, but there has been a major effort to deny this and deny N95s to health workers. "They caught it at home" is said when they get sick or disabled by viruses. 1/2

@loscharlos If Dr Thompson had been correctly told Covid was airborne in early 2020, she’d have worn FFP2, and not have long covid now.
English
@loscharlos Way back I wrote about risk and responsibility should be a fair exchange: paulhammant.com/2020/04/04/ris…. All the correct point made by the reality was far worse - long covid wasn’t known to me at the time.

story truly inspiring.
Thomas Talhelm started by solving a problem in his own apartment, then shared that solution with the world — that’s how real innovation happens.

@CleanAir4KidsUK Sadly, this government document doesn't mention energy recovery ventilation (ERV) or similar.
English
It's good to see Govt giving attention to ventilation. But still the proposed CO2 limit is too high.
Experts have recognised for years that it should be 800ppm.
But the big question is... Where is the funding?
For schools to actually do this.

@drseanmullen Liability is the way forward here. It'll take a union to push it though. Me at the start of the pandemic - paulhammant.com/2020/04/04/ris…

Required to attend a 2026 meeting of health behavior change scientists:
“Exposure or infection may result in… permanent disability and/or death.”
“I hereby release, covenant not to sue… arising from or relating to illness, disability, or death…”
Risk acknowledged. Liability transferred.
