With many people getting COVID from the summer surge, a reminder that the CDC's isolation guidelines are inadequate.

CDC shortened their isolation guidelines, not because of a change in the science, but in response to political pressure to keep people working even if they are sick.

Science shows most people are infectious for 10+ days; it's best to isolate until you test negative on multiple tests. If you can't stay home the whole time, wear an N95 mask to stop the virus spreading to others.

@luckytran conflicting stories . One says your no longer contagious and others do Not agree Have covid 22 weeks

@luckytran asymptomatic cases account for 20-40% of all infections but the graph seems to show infectious viral load increasing rapidly from symptom onset for all 3 variants. Would the shape of the graph be similar for asymptomatic cases, and would the maximum load be the same?

@luckytran
I was told once by a nurse that PCR test could give back positive test for several weeks (more than two) after an infection and that it wasn't a reliable method to know if you could stop strict isolation

Do you know if that claim holds any water per chance?

@knight @luckytran I am not a doctor, but my understanding is that PCR tests look for DNA remnants of the virus, which can remain even when the virus has been neutralized by meds, the immune system, etc. It can take awhile for those remnants to be completely eliminated from the body, and PCR tests will show positive until that time (in other words, it will be positive due to a previous infection)…

@knight @luckytran …leading to higher risk of false positives (alerting to an infection that isn’t actually there). Rapid tests, on the other hand, look for active infections (so better for judging when to leave isolation), but aren’t always as sensitive as PCRs. So rapid tests have a higher risk of false negatives (missing an infection that is actually there). If I’m misstating or misunderstanding this, I hope a medical professional will correct me.

@ecoscore @luckytran

#COVID is so much worse even than is recognized. And when you consider the accumulative impacts and pair that with societal responses and #climate change, well...

It ain't pretty.

In point of fact it is dire.

In running through that in detail with #Claude, it concluded there would be a likely 50-70% die off of humans globally by 2050.

That is how potentially bad. And that is likely an underestimate.

#COVID..ansteckend mit #COVID19?

Studien legen nahe, dass:
- Die meisten Menschen sind ~10 Tage lang infektiös.
- 80 % der Personen werden 5 Tage nach Auftreten der Symptome positiv getestet.
- Nur 30 % der Personen, die positiv getestet werden, haben #Fieber.
- Das Auftreten von Symptomen ist ein unzuverlässiger Indikator für die Ansteckungsfähigkeit
- Personen können bereits vor dem Auftreten von Symptomen infektiös sein
- Asymptomatische Fälle machen mindestens 20-40 % aller Infektionen aus

@luckytran @MyIgel 10+ days of COVID self isolation are nice ideas, yea, but can we please start with the basics: IF YOU ARE SICK, DO NOT COME TO THE OFFICE.
(yes, i'm looking at you, dear colleague -_-)

@luckytran When I got Covid I was testing positive on a rapid test for 21 days straight, it was wild.
Show threadHulk Smash COVIDJul 22, 2024
@luckytran It's true, numerous studies show that vaccinated or not, symptoms or not, people can easily be contagious for 8-10 days spreading viable Covid, some to 14 days, and immunocompromised even longer. And it can take time to show up on a test after you've got it. Which is interesting bc Kamala Harris' husband had covid 2 weeks before Biden got it, and they all hung out on the 4th. But it could a been anyone, it's surging. Just though that was interesting timing-wise.
