We testified today at a closed door meeting where @CDCgov HICPAC Commitee recommended that #N95s are no longer needed to prevent #COVID19 transmission, although #COVIDisAirborne

First and foremost, the public should be included in the development of public health and PPE guidelines, including impacted workers, and unions, and patients and communities and utilizing the expertise of occupational health experts, industrial hygienists & aerosol scientists.
#N95RespiratorsWork and #COVIDisAirborne.
Decades of science support the efficacy of #N95 Respirators. The appropriate way to assess efficacy of PPE is via engineering assessments not by experimenting on health workers by exposing them to lethal and disabling pathogens via RCT Screenshot of Fact sheet Ti...

Give everyone N95s to deal with poor air quality from wildfires, & reduce Covid infections. Reinstate mask mandates in healthcare settings. Quickly transition away from fossil fuels. Plant lots of trees & hemp. End poverty with a substantial UBI, & provide good healthcare to all.

Gentlemen, if you don't wear masks in public, I assume you're flaccid.

Shout-out to all the men masking up and rocking #BigMaskEnergy in elastomerics and #N95s.

“I’m super cautious but…”

A 🧵of cognitive dissonance on unmasking.

All anecdotes are sanitized composites to protect identities.


“My family is super cautious. We wear N95s everywhere. But on weekends, my kid plays travel hockey and is unmasked while playing.”

“I’m taking Covid really seriously and advocate that everyone mask. Let me just take off my mask to give a speech about Covid sequelae at this academic conference I’m attending.”

Met my GP today. He had COVID a few weeks back. He was shocked by his fatigue so he was willing to chat with me and learn from my experience with #LongCovid. There was a lot (a LOT!) he didn’t know. 1/5
He said he couldn’t find the energy to exercise. I advised him to wait eight weeks before exercising again to avoid lowering his baseline for Post Exertional Malaise. He never considered that was a possibility. #PEM. 2/5
I advised him to take Natto/Serra as a a prophylactic against clotting. #TeamClots #nattokinase. I also advised him to use @enovidTG as a nasal barrier to avoid viral load in the event of reinfection. 3/5

CMOH Kieran Moore wants you dead.

H/t @DFisman for putting me onto the term “necrosecurity”.
@DFisman I didn’t think I’d have occasion to use it so soon after learning it. 😱

Last weekend I needed a new dishwasher installed, but the installation techs arrived wearing cloth masks, one with the mask falling off his face.
When I asked them to wear high-quality #N95s (which I offered), or at least something that would cover the nose, they REFUSED. 🧵
One of them said: "I'm the boss here and we wear our own masks. If you need us to wear something different we will leave, and you can wait until the pandemic is over to get a new dishwasher."
I should be able to keep the air in my own house safe. #COVID19 spreads in the air like smoke, when people breathe, talk, cough or sneeze and the virus can remain suspended in the air for minutes to hours after an infected person leaves the room. Two images on top of each other. First image shows an infect

As if you needed reminding.…

'A well-sealed FFP2/3 [N95/N99] mask is the single greatest tool humankind has come up with to prevent initial infection, further spread and mutations - as well as an endless pandemic.'

I hadn't realised that the 'Vax-Only and Nothing Else' crew were a thing; or that they are so incredibly toxic & wrong-headed; and as dangerous as any of the other extremist Covid bands.

A thread on putting them right: and why vax-and-mask matters. ImageImageImageImage

CDC came out with another incremental update on #mask & #respirator guidance today:…

Clarifies N95s aren't in short supply & can be worn again!

It's still not perfect, but it feels like we're at least inching in the right direction. Some thoughts via a🧵.
2/ New statement that most respirators (i.e. #N95s) "are disposable and should be discarded WHEN they are dirty, damaged, or difficult to breathe through."

So you CAN #ReuseN95s‼️
See, e.g.:

That's *much* better guidance than to toss after a single use!
3/ Also clearly states that:
"Loosely woven cloth products provide the least protection ... and well-fitting NIOSH-approved respirators (including #N95s) offer the highest level of protection."

1/ SARS-Cov-2 is airborne and always has been.

Here's a quick 🧵 on where to find high-quality, made-in-America NIOSH-certified N95 masks that you may not know about.

Disclosure: I have no relationship with these companies, just an abiding interest in a secure, healthy USA.
2/ Indiana Face Mask Company.

Vertically integrated manufacturer that scaled up a new factory to ensure a secure supply of USA-made N95 masks. Quantity discounts available. Affordable.
3/ ReadiMask.

Maryland based company producing the only NIOSH certified, STRAPLESS N95 mask. They also make a version with an integrated face shield. If you want a FULL SEAL, then this is the mask for you.…

Here's what @xiaoxuyvr just asked Bonnie Henry and Education Minister Whiteside about #N95s. #BCpoli #BCed
Dr. Henry says these experts don't take into account the extra layers of protection afforded students in particular: it's the same people mixing the whole time and daily screenings should filter out #COVID19-positive people. #BCpoli
Dr. Henry says "we need to be pragmatic and practical" and reiterates her recommendation that the best mask is a good-quality one that fits snugly and that you wear. Here is the 2010 study we referenced: #N95s #BCpoli #BCed

2) Since that video premiered last year, I would add that we should now use PREMIUM high filtration KN95 / KF94 / FFP2 masks or better. Many countries in Europe already had mandated these premium masks in Jan 2021 already. We should too, especially when many others don’t mask.
3) Another strategy is to DOUBLE MASK. I first recommended it in October 2020, and the anti-mask haters came out in force trashing me… they also trashed Biden too, but hey…

A 🧵 to counter some confusing messages about masks & wildfire smoke (1/x)

1. High-quality masks (i.e. #N95) best for both viral aerosol + #wildfire smoke
2. N95s readily available & should be used for both
3. But other masks can provide non-zero benefit…
2/ The #CDC and #EPA both strongly recommend upgraded masks (respirators) like #N95 or #KN95 to protect against wildfire smoke. I totally agree (unless using something even better like N99 or elastomeric), b/c these filter the smallest particles very well.…
3/ But the #CDC also says not to use N95s, b/c they "should be reserved for health care workers." I totally disagree, as do countless others, b/c supply chain problems in 2020 have recovered in the US.

Stronger prevention against the aerosol component of COVID spread is absolutely crucial for public health, especially healthcare. Major pushback against this has cost many lives. Please listen (2 min) to the best reasons why this WHO leader says they are not worth it. 1/
2/ In relation to the comments by Dr. Conly about N95 risks to pregnant women - this is a nice thread by @caruzycki showing major errors in how that study was designed. Authors modified an N95 mask until it was very to breathe through first.
3/ In contrast, there are lots of legitimate & very important reasons to use upgraded masks (N95s, elastomeric respirators) - because they protect lives.

1/ In context of extra precautions against new COVID variants, some new questions pop up about #masks.

Article by @cwarzel @zeynep asks/answers some good questions to start. Other thoughts in a 🧵, e.g. N95s, fit (Tw7+ ⬇️), when to replace (Tw25 ⬇️), etc.…
2/ Countless recent articles w/ interviews from relevant experts imploring people to still take mask-wearing & overall airborne COVID health seriously.

One of many, here by @skbaer w/ broad contribution. (Tw33 below has link to a compilation of more).…
3/ Many good arguments recently towards motivating broader use of #bettermasks, i.e. #N95s. So if not using already, consider.

See e.g. this editorial by @j_g_allen:…

Or this opinion-piece by a group of excellent scientists:

Background: Healthcare workers are at ⬆️ risk for #COVID w/o adequate #PPE (20-30% of cases). In #GI, upper scopes are aerosolized-generating procedures (AGPs) & therefore even ⬆️ risk for #COVID. Lower scopes also = ⬆️ risk 2/2 some e/o AGPs w/bx + fecal oral spread. 2/13
Rec 1: Wear N95s (or better) for all upper scopes REGARDLESS of #COVID status. (Strong rec, mod quality evid). Why? Testing is inadequate & w/community spread, take universal precautions. If rapid testing for endo pts is avail, prioritize #N95s for known COVID 3/13
