In a viral surge, time is everything, esp with exponential spread. It means you cannot reasonably vaccinate your way out. You cannot depend on test results that take days to come back. You cannot hedge on quarantining or isolating. You cannot wait to start using better masks.
2/ You essentially need a way to stun transmission. Many have called for circuit breaker events in which any social interaction that could introduce transmission stops altogether outside of households (a “lockdown”)
However, I don’t think this is necessary to achieve this.
3/ This was part of our proposal in May 2020 in this piece. With enough people wearing the right respiratory protection— that is, masks with excellent filtration AND source control— you could achieve close to the same thing without shutting down.
Now despite vaccines and high levels of population immunity, we are faced again w the problem of slowing transmission— because w #Omicron, even small % of large number of cases is a large number of cases w/ limited hospital beds

So there was a respirator FOR THE PUBLIC for emergencies such as a PANDEMIC by 3M from 2008
How in the hell did CDC recommend cloth masks for this long instead of pushing the federal government to scale up production for every single American immediately 2 years ago?????
And this looks *a lot* like the 3M 1870– the respirator that is so comfortable I did an entire workout in the gym with absolutely no issues at all if we are going to bring this back to N95 being ‘uncomfortable’
One of the problems w/ CDC isolation guidelines is it hinges on many assumptions, some which may be clarified with more data tomorrow, and others which cannot be clarified or even really monitored/guaranteed by any means
1/
First assumption is that most people are barely transmitting after day 5. This might be true- but I haven't seen that data the way it was shown for transmission early on which helped to create the 10 day protocol
Esp need that data for people w/ Omicron specifically
2/
Second assumption is that people who are done isolating and feel better will actually wear a mask at all
Third assumption is that cloth masks or whatever people are using that are not high filtration actually have good source control (no good data saying this is true)
3/
1/ People are rightfully concerned that cases who are out of isolation too early can still transmit (they can)
And CDC guidelines hinge on people wearing masks for the 5 days after (they should)
But they should be wearing a high filtration mask.
Better source control.
2/ Part of our push for HiFi masks was not only to protect the wearer, but also to protect those around the wearer esp because people transmit before they show any symptoms at all
3/ From NIOSH scientists on source control provided by cloth masks versus respirators here
Respirators are much better. Fit is of course still very important as well.
My interview with @NYMag on why cloth masks don’t cut it — this is the time, esp during a surge like this, to wear the best respiratory protection that you can.
The science is clear: virus is airborne; high filtration masks work, regardless of variants.
2/ Here are two high filtration masks that I have worn that I find are comfortable, breathable, & have NIOSH certification (see next tweet for the other)
I do not know *anyone* who actually wants lockdowns. Literally no one wants that
What is crazy to me is that if Americans had the right masks from day 1– we would never have had to shut down
Instead- we had “don’t mask” then cloth mask/ bandannas; & even now, not much better
2/ To me, this is not about Delta or Omicron or whatever comes next.
It is about being *prepared* so we aren’t left scrambling again
So we aren’t talking about lockdowns or what to do with schools or businesses or hospital beds
So we all have access to excellent protection
3/ Even after the #Omicron wave passes, having a robust supply of high filtration masks for the public — for if/when we may need it— must be a priority for the @JoeBiden administration.
1/ Controlling the epidemic such that we don’t have surges & keep infection levels low doesn’t hinge on any one solution but the combination of many, done right
We have pushed for #BetterMasks with the expectation that only some people will wear them. But that this still matters
2/ No intervention will have 100% uptake
And every intervention has benefits and costs to the individual (diff for everyone)
Rapid tests, HiFi masks, vaccinations, air filtering products, avoiding social gatherings etc etc
Goal is to avoid surges, not elimination of virus
3/ When we have infection surges, the benefits of each intervention grow even more, relative to their costs
The combination of these tools applied at the right time by enough people can stun epidemic growth
But they require coordinated leadership & public buy in
