3/ There would need to be some vetting by CDC/NIOSH & other private labs to quickly assess mask quality.
We need DPA/American manufacturing to help ensure a continuous supply of verified high filtration masks.
Priority for high risk &/or high exposure + unvaccinated folks
4/ These masks will still be needed post-vaccination campaigns during vaccine booster campaigns, which we expect will be needed esp in light of new variants.
Fit is key- meaning annual fit testing is key as well. This should become integrated into primary care clinics etc
5/ Policy must follow supply- meaning if we are to mandate high grade masks in high risk settings during future surges, that supply must be brought to the public, esp to our most vulnerable.
Masks can be shipped home; alternatively or in conjunction, vouchers can be given out.
6/ Other countries used post offices and/ or vending machines for pickup.
We could have this at grocery stores, pharmacies, & other public spaces for people to access the masks.
There are many ways to get there
7/ There are trade offs to any decision.
Focusing on better masks may take attention away & public health departments are limited like any other entity
While cases have slowed, the administration could/should use this lull to begin cleaning up the supply chain for #bettermasks
8/ Ultimately, I think that vaccination campaigns are the bigger priority if the government is unable to do both right now
But I also think that #bettermasks are both a short and long term strategy to protect again respiratory pathogens/ future pandemics. #covid19

Thanks @drsanjaygupta for the shoutout! Absolutely agree- high grade masks like N95s in all high risk settings can urgently curtail superspreading/ drastically slow spread- critical while we vaccinate. Hopeful @JoeBiden admin will operationalize #BetterMasks for #covid19 control
2/ @RanuDhillon@sri_srikrishna & I have a piece coming out shortly on this topic this week with more specific thoughts that raise the bar above double-masking, which is a backstop for the time being. #covid19#BetterMasks
3/ not even clear that *supply* is the issue! Need to actually move existing supplies into healthcare and other high risk settings, & also continue to manufacture thereafter— but more than anything, need an organized strategy. #covid19
It’s been a long year, & I can sense hesitancy from the public health community about being too vocal on what is “safe”— but once you are fully vaccinated, you have excellent protection from severe disease!
When around those who aren’t yet vaccinated, wear a mask ⬇️
But- this needs to be about more than mandates; needs to be about getting people to understand & implement masking when/where it is most important (often, not outdoors which is where mandates seem to be focused)
2/This is not to say outdoor transmission doesn't happen.
But it is presumably much lower than indoors.
Indoors includes public spaces. But it also includes unregulated private spaces.
If people believe in masks as protection, they will use them.
3/ Understanding drivers of ongoing transmission- the where/when/why/how (@RanuDhillon) continues to be key.
Beyond frontline workers who are getting infected in the workplace (which should be a main focus of our interventions/support), where else and how else?
Some of the framing around impoverished countries not getting adequate vaccine doses center on this being bad for wealthy countries because there will be ongoing reservoirs of disease/ more mutations etc
Why is the framing always relative to the effect on wealthy lives?
2/ Why is the focus not on equity?
Why are all lives not treated equally?
Why are impoverished countries seen as vectors of disease rather than places with human beings deserving of vaccines like everyone else? #covid19
3/ I ask these questions of course rhetorically.
This is always how it has been.
This is not surprising.
This has been every part of the pandemic, from testing, to treatment, to vaccines. #covid19
2/ Simulation set in a 10x10 foot chamber; aerosols generated simulating someone doing “light work” load and the receiving dummy doing “moderate work”
Pic below of some key mods as described:
3/ “Ten mask combinations, using various configurations of no mask, double masks, and unknotted or knotted and tucked medical procedure masks, were assessed”
Short Thread 1/ Another must-read piece from Dr. Mike Klompas @BrighamWomens - lead author of the recent #covid19 outbreak study from our hospital in @AnnalsofIM- I've been lucky to call Mike a mentor this year & have learned a lot from him
What is an AGP? jamanetwork.com/journals/jamas…
2/ "It has become clear that the traditional dichotomy b/w droplet vs aerosol-based transmission is overly simplistic. In practice, people routinely produce a profusion of respiratory particles in a range of sizes that incl both droplets & aerosols as well as particles in b/w"
3/ "Respiratory particles of all sizes can carry virus and all are potentially capable of transmitting infection. The amount of respiratory particles one emits varies by activity. Quiet breathing generates a small but steady flow of aerosols." #covid19
