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.
Ideally store below 80F
Using the test in the cold can cause false negatives Bc the reagents may not bind virus well or show a line.
It’s ok if your nose is cold and the test is warm. But maybe let your nose warm up a bit too before swabbing.
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.

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

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

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

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.
