I think S.Korea has lead research in this area...

South Korea’s New Coronavirus Twist: Recovered Patients Test Positive Again


Doctors believe that the disease may have gone dormant and then come back, posing more challenges for testing

SEOUL—More than 160 South Koreans have tested positive a second time for the coronavirus, a development that suggests the disease may have a longer shelf life than expected.

Many had volunteered for re-examination after exhibiting symptoms such as coughing. Others submitted to extra testing on little more than a hunch despite not showing symptoms. So far, these patients—all of whom needed to twice test negative before leaving medical supervision—haven’t spread the virus to others, local health officials say.

...

Can You Catch Covid-19 Twice?

...Then why are some people testing positive again?
Roughly 450 South Koreans tested positive for the virus again after meeting the criteria for recovery and being discharged from isolation. The Korea Centers for Disease Control and Prevention re-tested more than half of those people and found no evidence of the live virus circulating.

Peer-reviewed research studies have shown that viral fragments can circulate even after an individual is symptom-free. That doesn’t mean that people are still sick or infectious....

I'm not seeing this. The bit you refer to seems to simply be an arbitrary update to guidance - if you're had corona in the last 3 months you don't need to worry about quarantining after exposure to an infected person. It's not a statement that immunity only lasts three months. The CDC are simply setting a lower safe bound on probable immunity in their guidance, not an upper one.

I am well aware how different turnaround times can be depending on a variety of factors, but I've seen only a handful of people say they were quoted such a long time. Sorry you were one of them.

I have to say $140 is straight stratospheric pricing for an antigen test. Which one was it, do you know? BD, Abbott? BD tests are costing providers $30-40 per test right now, less if you're buying a crap-ton.

Something else everyone should be aware of (this may have already been discussed here): several states, with more to come, are NOT INCLUDING rapid positives in the PCR-based Covid case counts (the state/country counts we're all familiar with). States are going to pivot away from reporting these big daily numbers and say these tests are for screening, not diagnosis.

Here's Maryland's health commissioner saying all this plainly https://www.delmarvanow.com/story/ne...ta/3373740001/

Re: Coronavirus

As long as they're followed up with a confirmatory reliable diagnostic test (they seem to be), it seems reasonable to exclude tests with large false positive rates, especially if overall test positivity rates are low.

Bottom line we just don't know yet re: C19.

That's the problem, this will not always be the case. Insurance companies are already refusing to pay for a rapid + PCR test. Perhaps it's growing pains and will get sorted out but I would expect positivity/overall case counts to be much less reliable as states transition to rapid tests.

My understanding is that the antigen tests have more false negatives, but false positives are very rare. So there's no reason not to count the positives.

Re: Coronavirus

Reading posts from the beginning of this thread is hilarious. The complete inability to understand how exponential growth works was very annoying early on. As an American that was trying to explain this to people early on..... lol. Don't respond to this post, I just remember dealing with these type of people personally and it was very frustrating.

Re: Coronavirus

Dude there's still tens of millions in the US alone that have evolved zero on the severity/personal responsibility of this.

I used to have a cleaning service come to my house every 2 weeks until March. I just (tried to) start back up with them last week, after having multiple conversations with the owner in the days leading up about the employees wearing masks while here (I said not masking is fine when we were not home but on this particular occasion we needed to be). So the crew arrives and comes in, sans masks, and then both tell me they won't put one on b/c they can't work in them. So I said ok, then you're not cleaning the house, and made them leave, and they were pretty *****ty about it. I called the owner and he said they had told him it would be fine to mask up, so I wonder how often that happens, they show up and do this and people are too courteous to say no.
