how can he be sick today and be involved with the team less than 10 days from now in any way?

He tested positive, but does not give date of positive test. Testing positive does not mean you are necessarily sick only that the virus is present. If he tests negative before the game then there would be no reason he could not coach.

then why are we making people quarentine for 10-14 days in all these sports once they have a positive test. Most Colleges are doing it for kids who test positive.

Out of an abundance of caution?

Looks like I'll be hitting the bottle early today.

Initially the 14 day quarantine was for people that were potentially exposed when testing was limited and that was the maximum incubation period. I would think it could be shorter now with testing, but, if exposed, the virus still has to have enough time to proliferate for a truly positive person to test positive. I don't know if we've established that time table. That may still be 14 days.

NFL is using
asymptomatic 10 days since the positive test or 5 days plays 2 negative tests .
10 days if you have symptoms and a positive test and 72 hrs with no symptoms after that.

so he would fail under NFL guidelines just with the 10 day rule but have a shot on the other part

That's the problem with all these stats out there and so many false positives. The tests are too sensitive with too many "spins". Thus, these tests are picking up virus debris of someone who may have been exposed months ago and the test picks up viral debris after the person had it and is now healthy. Cant count on the test, too sensitive. This may be the case.

Good point, but now 7 months into this, we don't have a reliable test and it's just crazy. False positives are all over the place.

 

[upperdeck]

you wouldnt need as reliable tests if you had enough to do them multiple times.

The theory early on was that an incubation period of 14 days, and if you were beyond that there was little danger of you passing on the virus if you had no disease symptoms. That has since been reduced to 10 days.
It is more reliable now to say disease(symptom) free with a negative test after exposure, because if you are testing negative there is little chance you can pass the virus.
You have to remember this has been changing rapidly with a greater handle on what we know.

As a medical expert let me clarify a few things. Official CDC guideline is after testing positive you are cleared 10 days after the onset of symptoms, or if you were asymptomatic, 10 days after the initial test - assuming you are 24 hours of being symptom-free. As far as retesting after having an initial positive test there's a lot of misinformation out there. Patients with covid will likely test positive for about 90 days as they continue to shed small amounts of virus, assuming the test platform is PCR technology and not a worthless rapid antigen test. However it is felt that after the 10-day window patients are no longer infectious although they still will test positive so the notion of having to retest after already testing positive is absurd.

Are you saying if you are PCR negative you could still spread the virus, because I do not believe that to be the case?

Not really “likely to test positive for 90 days” but a minority of people can definitely test positive for 90 days.

I don’t see that in his post.
But keep in mind the tests are not 100% sensitive and if you don’t get a good sample sensitivity goes down. In the setting of a negative test after the 10 day period It is highly unlikely that someone would spread the disease.

What I am saying is that the vast majority of patients will still have detectable virus well after two weeks if PCR testing was to be repeated...now to make things more complicated there are several different PCR tests all that detect virus at different levels. For example BD Max detects 40 viral copies, GenMark detects about 250 copies, Diatherix detects about 2,000 copies, and LabCorp detects about 6,000 copies of viral DNA. So it also depends on what test you use. Some tests are far more sensitive than others. However as I said earlier, as long as patients are not having symptoms, they are not felt to be infectious after 10 days nor able to transmit the virus at that time. If they are still having symptoms then things are different. Most patients will fall into the asymptomatic category at that time unless they were hospitalized and acutely ill with evidence of lower respiratory tract disease on imaging studies and with elevated inflammatory biomarkers. So back to my original point...It is fairly garbage when you hear people say they're going to be retested after already having laboratory confirmed positive PCR. It is pointless. And they probably would use an inferior testing method to get a negative result, possibly using saliva as opposed to nasal pharyngeal swab. As you can see there are a lot of nuances to this and people can leverage it however they want. I would not be surprised if they use a rapid antigen test to get a negative result because those immunoassay will not stay positive for long as opposed to molecular tests like PCR.

a negative pcr test- if properly collected- is very good at ruling out an active infection and whether or not you still are capable of spreading virus.

a positive pcr is not so great for determining if you are still infectious or not meaning you can still have detectable virus but that virus is not capable of infecting someone else. That’s why the CDC has shifted to 10 days from sx onset for mild to moderate cases. They looked at this and were unable to recover virus capable or replicating beyond 10 days of when sx start.

Yes and no. It’s not a false positive. That person most definitely has or had COVID.

If it is a PCR test, it is picking up viral RNA. It doesn’t tell how much of the virus is present, or if said person is still contagious. That’s why the CDC has changed guideline of quarantining. 10 days if asymptomatic (or 2 negative tests) or 3 days after fever free with no meds.

 

[CIL]

You can absolutely get a false negative w/ a PCR test - if you are in contact with someone who has the virus and rush to get a test, it may not show up on a PCR...yet. That’s why they advise to wait 3 or 4 days later to get said test, if that makes sense.

Wow, interesting and thank you for the info

Nicely avoided answering the question.

True, and poor sample collection can also give false negatives.
