We have either rapid re-infection, or rebound #Covid19 after Paxlovid, in my own 🏡 . Vaxxed & boosted. Symptoms & rapid test pos 5/2, 5d of Pax 5/4-5/8, all symptoms gone, neg rapid test x 2 5/8 & 5/9.

5/16 new symptoms & RAT instantly pos (📸). Our #MedTwitter 🏡 is weary. Image
By the way, the right answer is not “So Paxlovid doesn’t work.” It works very well to ⬇️ risk of severe illness, which matters a lot. And right answer is not “so let’s just give 10d.” Right answer is we need data to understand this phenomenon & direct rational antiviral use.
I’m sharing this because:
👉Anecdotes can generate scientific hypotheses that THEN MUST BE STUDIED WITH RIGOR &
👉The public needs to know for #publichealth reasons that, one way or another, we can end up symptomatic & contagious again a wk after apparent #COVID19 recovery.
The best reaction to hearing this whole story is: I’m going to #WearAMask while this all gets sorted out.

P.S. We’re a 2 dr household (including one infectious disease physician), & that’s what we’re doing too. #MedTwitter

Adding a P.S. since I’ve gotten a 🌊 of msgs about this tweet today. I’ve now seen credible anecdotes from drs I know personally of the same “rebound” or prolonged positive rapid tests out to 3 wks occurring in pts w/ #COVID19 who have not received ANY treatment, incl Paxlovid.
This leads me to wonder if there’s a big difference in viral kinetics w/ 1 or more of the #covidvariants. It’s poss the current virus takes much longer to peak or to clear. All of this can/should be formally tested. Anecdotes generate hypotheses; they never ever replace science.
5/19 Update on reinfection or #Paxlovid rebound: Symptoms substantial (sinuses, sore throat, very runny nose, fatigue) & rapid test still riproaring pos, even faster than before, ie, super contagious. (NB. Pos control line is faint but there & got redder shortly). 👎 #MedTwitter Image
Somehow forgot to mention cough, which sounds like it would be productive but is not. Goes day and night, nonstop, preventing all rest. #MedTwitter
5/21 update for those tuning in to our #COVID19 sanatorium. Rapid test still raging pos. Now d6 since onset of rebound symptoms with pos RAT, d20 since 1st pos RAT. We need a prosp study of ppl w/ delayed viral clearance. May teach us a lot re #longCovid. @VirusesImmunity Image
Why aren’t we requiring neg RAT to exit #COVID19 isolation? Overdispersion means that a very small % of those infected cause most secondary transmission. Are ppl w/ robust viral replication for wks the culprits? We could find out! If we want to end the #pandemic, we should…🤷🏻‍♀️
Finally, it’s clear that we need robust sterilizing treatments for #COVID19. Whether we use them to interrupt chains of secondary transmission for #publichealth reasons or potentially to prevent/treat #longCovid (note: HYPOTHESIS ONLY for latter), we need them. #MedTwitter

So I wasn’t that worried a few hrs ago. This dials it up a little.

For anyone who has ever played the collaborative board game #Pandemic, you may know how it goes when there’s uncontrolled spread of one pathogen throughout 🌎 & then outbreak of a new one in mult countries. 😖
The current #monkeypox outbreak now includes cases in #UK, #Spain, #Portugal, #Canada, #US…from what I’m reading, this sounds like person-to-person transmission, which historically was thought to be rare, & evidence of community spread. Wow. #MedTwitter

Smallpox vaccination provides at least partial protection against #monkeypox, but routine smallpox vaccination in the 🇺🇸 stopped in 1972. Most Americans under age 50, including myself, are not #vaccinated.

Per @NoNutTraveler, “the @united pilot came back, & he & the flight attendant began asking me if we had Epi-Pens. I said, of course we do. To which the flight attendant gaily said: ‘Well then, we can serve anything because he can just use the pen.’” NO! /1

This represents a fundamental misunderstanding of anaphylaxis, including #peanutallergy. In fact, this fallacy—if you’ve got an Epipen, exposures aren’t a concern—was the topic of a past corrective ad that FDA required the maker of Epipen to air. /2 mmm-online.com/home/channel/o…
I’m speaking here as a dr & the mom of a kid who has nearly died of inadvertent peanut exposures even with an Epipen, which we always carry. Airlines & the public need to know that Epipens are a rescue med, not a preventative, & do not eliminate the need to avoid the allergen. /3

Lots of chatter in my feed & my DMs this AM about Paxlovid & “rebound.” Let’s be mindful of the diff ways this term is getting used & interpreted, #MedTwitter. Some are referring to return of symptoms after feeling better, others to triggering more severe symptoms… /1
Others are using “rebound” to mean going from rapid test neg (not contagious) back to positive (contagious) again; still others are using it to mean increased short-term risk of new infection w/ same #Covidvariant. People are suggesting alt dosing, duration. Stop, stop, stop. /2
Learn from #pandemic yr 1&2. This conversation has gotten way ahead of the data. We risk inadvertent #publichealth harm from the mis/dis-info machinery if we speak/act imprecisely here, esp without data. Next tweet has an article w/ a good summary of what we do & don’t know. /3

Here are 2 family members, similar ages/#MedTwitter history, #vaxxed & #boosted, dev symptoms & tested pos same day, got Paxlovid same day. Day 4 tests below. Why are we still using a 'one size fits all' strategy to exit isolation when rapid tests are readily available, @CDCgov ?
I doubt policy will change (note: shortening isolation to 5d was done to minimize societal impact from loss of essential workers to isolation in Jan #Omicron wave), so you should choose to rapid test to exit isolation. A positive = contagious, no matter how many days it's been.
Here's another example. Two more people, again similar age/health history, both vaxxed and boosted. On the left, patient #1 on day #13. On the right, patient #2 on day #5. We'll see what happens with patient #2 but I'd be willing to bet they can leave isolation well before 2 wks.

There's another 🌊 of #COVID19, y'all. I have gotten more texts since Mon asking questions about monoclonal antibodies, about Paxlovid, about rapid tests, & on & on than I have in the whole month preceding. Be aware. All these folks tested at home & are uncounted in tallies.
This is anecdotal, but a pattern recently: people staying pos longer on rapid test. Here's an older pt, 4 doses Moderna #COVID19 #vaccine, mono Ab on d1, feels 100% now, & still quickly/strongly pos (ie very contagious) on d10. Had he not retested, he might be infecting others.
@CDCgov shortened isolation to 5d in Jan b/c they were concerned society may fail to function w/ huge #s of essential workers out for 10d in #Omicron surge. This has to be changed. People are leaving at d5 w/o masking or testing. They need to rapid test to exit or isolate longer.

Invited to a destination wedding earlier in Apr. Awesome place that holds a special place in my ❤️(Vail). Lots of people I miss. All #vaxxed. Many boosted. No masks required. No rapid tests. Declined. One positive couple next AM. Groom & all but 4 guests got #COVID19. #pandemic
In care you’re wondering who did NOT get infected, the common elements were 4 doses of #COVID19 vaccine OR known/suspected past infection + 3 doses of vaccine, with last dose being recent.
That includes the bride. But if you want to know how to put that “in sickness and in health” thing in action, having discordant #COVID19 test results when you should be honeymooning is one way. 🤒👎

I now know where Paxlovid is & isn’t available is about a third of US states.
