Informal survey!
People who got infected and were able to test frequently during this recent Omicron wave.
On what day did you stop testing positive? (Day 1=first symptoms or first positive, whichever sooner. If no symptoms, day of ve+ test).
Please RT!
Tests pics welcome!

Interesting survey & we will likely see lots of heterogeneity here. It will be different for vaxxed vs unvaxxed vs boosted, & age, sex, comorbidities could influence time to negativity. The most imp thing to find out for the ph policy is the average time for the general pop.

I’m hoping there’s a study soon of viral load kinetics for Omicron. I did the survey because of many anectodal reports of ve+ people well into day 8-9 and beyond even among vaccinated/boosted, seems bimodal. Especially a question for people working with vulnerable populations.

Interesting. Tho it's *viable* virus kinetics that really counts, especially given the harms of self-isolation. Also this partly explains why we are so short of tests - people posting 10 day series on Twitter over the holidays.

Lots of people test frequently for work and contact with vulnerable people and because of the burdens of isolation so I’m not going to blame them for why we are short of tests, especially since many other countries seem to manage this even under the Omicron load.

And, yes, it would be good if we could tell people something data-driven about *viable* virus kinetics for this variant.

Really it's contact tracing data that will be most useful to inform isolation period policy, over viral kinetics and LFT/culture positivity.

Sure, though those are harder to come by. All evidence would be great. Right now people want to know if they should see their grandparents if they’re still antigen positive on day seven or eight or nine. Or what should nursing home policy should be?

Of course they should not see their grandparents or any people at high risk when they are antigen test positive. For this, it is irrelevant whether the average person is still positive on day seven or not.

Personally I think it's unlikely that 3x vaccinated people who's symptoms have resolved for 24-48 h+ remain an onwards transmission risk, even though folks will continue to test LFT +ve. Ofc, until better data can give greater certainty there is a challenging risk calc to make..

Symptoms resolved and then 48 hours? Or day five and if symptoms resolved? Also many report congestion and/or sore throat but no fever. So very mild, but dark red test, turns positive instantly—into day 8, 9… Probably irrelevant for groceries in NYC but not for elderly visits.

You've just described me, albeit on day 6 so far...

Are you confirming these are omicron or could many still be delta? I assume yes they could be delta?
