Several counties in Colorado put a #MaskMandate order into effect starting today:…
It's a great time to remind people that masks aren't all the same. Any mask is more effective than no mask, but better fit & filtration quality upgrades protection.
Short 🧵
2/ There are so many great articles & resources on choosing a good mask, I picked just a few examples.
This article by @yeahyeahyasmin in @TheAtlantic is a great discussion of the need to wear #BetterMasks:…
3/ This article by @tanyalewis314 is another good example that goes through reasons for #BetterMasks.…
4/ This article by a team of high-level experts in bioaerosols & PPE from @CIDRAP wrote this more detailed article on the science of what masks can do:…
5/ If you haven't seen this article from Oct. 2020, it has some amazing visuals of how masks work -- from the perspective of a particle trying to fly through.…
6/ This article has some comments more specifically related to kid's masks, but the principles apply more widely as well.
7/ The CDC page on mask guidance took a while to be useful, but has made improvements in the last couple months and has some pretty good information now.…
8/ @CleanAirCrewOrg gathers info on various topics related to #COVIDisAirborne prevention. This page discusses mask quality & use:…
9/ I put a thread together in February of this year, especially to point out some of the important aspects of choosing a mask with better fit.
10/ This short thread by @CPita3 covers the most important pieces of choosing a good mask:
11/ You may have seen various people say choose a mask with good: comfort, fit, and filtration. I like the slight twist @meganranney put; choose a "good-fitting mask that gets WORN" well.
(But not a 'well-worn mask' like I recently said with confusion)
12/ If you're looking for info & testing on high-quality masks, @masknerd has done a great job of doing tests on masks & reporting freely via Twitter & elsewhere:
13/ Now that supply chain issues to buying N95 masks aren't limits, they can be a great solution for most people. You can buy them at plenty of local retailers; look for the NIOSH symbol. Or check out @projectn95, which is a non-profit that vets & sells high-quality masks.
14/ There are SO many good resources on why #BetterMasks are important, where to find them, and why. Just scan through the media tab here and search (Cntrl-F) i.e. for "mask."

I can't believe Colorado is actually having mtgs to draft possible care rationing plans before seriously working towards preventing people from being infected in the first place.

How is this the 21st century? We effing know how to slow it down, people. 1/…
2/ “I would hate to see… sending someone home who’s homeless”. Um, ya. I think that would pretty well violate medical oaths!

Draft plans being discussed in preparation for the possibility of hospital beds & staff being overwhelmed in Colorado.… Image
3/ But in addition to the obvious number of infections, hospitalizations, deaths, the horror of long-COVID, etc. -- there are plenty of other, less obvious problems already being caused by hospitals & staff being overwhelmed in the state. For example:

"On Friday night, Colorado’s COVID-19 modeling team released a new report warning that if nothing changed, 1,393 people could be hospitalized with the virus by late Nov.
It took less than three days to exceed that projection."

Article: @MegWingerter (1/x)…
2/ Data on vaxxed (breakthrough) vs unvaxxed cases & hospitalizations in Colorado always comes up as an important question. ⬇️

So get yourself & family vaxxed. But if even so, still important to be careful right now. #MaskUpColorado

3/ Unfortunately, it's not just one area of Colorado seeing spikes. This is somewhat anecdotal, but here are cases in one suburban Denver school district. Currently on a streak of six consecutive school days of new highs.

(dips each week on weekends when less testing)

Many are fighting hard at local levels for improved indoor air quality in schools (wrt COVID & beyond). One prejudice against portable HEPA purifiers is perception of "high-cost vs minimal benefit."
via @Ecole_Oubliee

A few resources below. Do you know other/better arguments? 🧵
2/ On the cost-effectiveness of HEPA filtration & ventilation. This @JohnsHopkinsSPH report from May 2021 touches into the cost of purchase & replacement for schools (+ much more).

Report via @polsiewski @ggronvall @WBahnfleth @Ep1Chrissy @Vahey_R et al.
3/ This article by Prof. Jensen Zhang from @EngineeringSU thinks through IAQ control strategies, but includes some discussion of portable HEPA filtration cost.…

The movement to bring #CO2 sensors to school empowers parents, students, & teachers to advocate for their health; Reveals invisible factors of air quality & helps see how well ventilation is matched to room activity.

Great article by @EmilyAnthes. (1/🧵)…
2/ If you are able to buy or borrow a CO2 sensor, stick it in the mesh water bottle pocket of your kid's backpack, pin into their shorts, or send in their lunchbox. Be creative. Make sure it isn't sealed away; the more airflow the better the reading.
3/ A key goal of #COVIDCO2 monitoring is to understand how well ventilation is matched to room activity & occupancy. Share the data with your school. If CO2 rises above 800 ppm, interventions needed to reduce build-up of aerosol & risk.

A “wellness” clinic in Colorado Springs has been barred from giving COVID vax shots bc of improper procedures.

The clinic “typically offers medical aesthetic services, such as Botox injections, laser hair removal, acne treatment”
“More specifically, clinic employees did not monitor storage unit temperatures for vaccines at all times and failed to use equipment and practices that comply with guidance from the federal Centers for Disease Control and Prevention, the news release said.”
“It is unclear if the Colorado Medical Board, which regulates doctors and other licensed health providers, or any other state or federal agency will take action against Dr. Moma clinic leaders.”
