This reminds me of early 2020 when we forgot so much of what we knew of epidemiology, immunology, infectious disease & thought we needed to rewrite textbooks. But we knew so much about this before it was ever detected
The reporting is really nice. But the title attached to it is frustrating to say the least.
It screams loudly and demonstrated well how we have thought about the importance of the unknowns compared to the knowns of this virus this entire pandemic.
3/
We have, and we continue to allow the UNKNOWNs to dominate our decision making when the KNOWNs are often MUCH more important
4/
For example, we KNEW that high virus loads are bad and mean you can spread the virus.
We KNEW that rapid tests turn positive when ppl have high virus loads.
Yet we failed to use rapid tests just Bc we weren’t sure how to interpret very LOW virus loads detected on a PCR
5/
So we chose to allow our incomplete knowledge about something that was *Relatively* less important prevent us from crucial tools that could at minimum identify every superspreader in real time.
6/
And Instead we used tools that we believed we understood and were therefore deemed the safer option, even if they were effectively useless for public health and what were trying to do - stop transmission.
We let our uncertainty get the best of us, and outshine all we know
7/
Back to this variant though, this is the most studied virus in history - easily (I think >HIV)
We know a lot about various mutations, we know direction that transmission will change. We know direction that immune evasion will occur. We know severity isn’t 10x different.
8/
We know this is an aerosolized virus.
We know we can make vaccines that will help against severe disease
We know that this virus is not Ebola and we know that this virus will not have a 10% mortality
We know that fomite transmission is minimal
We know it’s structure!

This 👆 is just a small snippet of so much that we know…

If using rapid tests this holiday season and asking ppl to test before a gathering… or any time…
Suggest they be done before leaving the house, or in the car, etc. Someplace >55 F
Also, if your counter or table or wherever you are letting them sit for the 15 minutes is cold (like a granite countertop) - place it on top of the box or literally any other surface that’s not cold (wood table, book, etc)
Also - this is not the same as storage. If they are sitting inside the box not being used yet, then store ideally in a slightly cooler location - but don’t let them freeze - it can potentially impact their chemistry.
Many countries are asking for proof of vax, or testing to travel
I don’t understand this. Vax work Well to stop disease…
But it’s time to clarify they do not stop transmission. They slow it down
But it simply is not appropriate to assume that vax = not infectious
1/
If we don’t appreciate this soon immediately, then we will see irresponsible policy that allows the virus to keep on spreading.
This is almost certainly even more true for Omicron which, if anything, will spread more efficiently, not less, than other variants among vax’d
2/
We can be fully transparent about what vaccines do very well (protect you!) and what they are not doing very well (stopping transmission) while still advocating for everyone to be vaccinated
Most ppl see this and any lack of transparency harms vaccine uptake even more.

This from @CDCgov is exactly why Rapid tests are important!
A PCR 2 days before an event, flight or (fill in blank) does NOT reflect you today
2 days ago can be neg but you can be a superspreader now
A rapid test used just before the event is always best.
1/
Its remarkable & contradictory that while CDC makes this figure 👆showing that neg tests 3 days before do not mean you’re negative on thanksgiving… while still recommending testing 2-3 days before travel.
The safest approach is to recommend a rapid test hours before travel
2/
In the midst of Omicron, instead of border lockdowns, we can use rapid tests just before a flight. Could even consider a PCR 24-48 hrs before amd a rapid test just a couple hours prior to flight.
