The problem is the same with sniffer dogs from both a PR issue and a security issue.  The public needs to know what happens if they are rightly or wrongly determined to be infected.  And will the various ports accept the "technology".  

 

What are the dogs exactly accurate for: covid, coronavirus or antibodies?  I really have trouble believing a dog can distinguish between two coronaviruses.  What if you have a common cold?

It's only a test to see if you have. It does not prevent you from catching it, which is what a vaccine does.

Not quite correct.

a hypothetical vaccine MIGHT prevent one from catching Covid19. Or, it might prevent simply symptoms to break out. We do not know yet, nothwithstanding some prominent figures lying about it for personal gain. 
Unless an effective vaccine is approved and ready for mass inoculation , we need to presume there will NOT be a vaccine and act accordingly.

You don’t need to be a stable genius to figure that out.

Most of the tests will indicate positivity when there are no symptoms, no reason to suspect this test will not. I have not heard any conclusive info on how soon after exposure a person can test positive....a positive test requires some establishment of Covid in the body. But how soon after exposure is the key. 

 

The press release was clear that it was effective within the first 7 days of symptom onset.  It was silent on the effectiveness of the test when no symptoms are present.

Well, there is the rub is it not. No symptoms identified by the person, but suddenly an issue from a blood test.

 

Standing at the pier ready to board and denied. Seriously who needs to spend hard earned $ for that experience.

 

Despegue - thank you also for your excellent observation on the effectiveness of a maybe in the future vaccine - good catch indeed.

Agree that is what the press release says, and nothing about how it works prior to becoming symptomatic. That doesn't rule out detecting positivity before symptoms. Many tests (I definitely know about the Hep C situation) detect virus when there are no symptoms.

The point is to prevent people from having it from getting on board— that will help others not catch it.
And the vaccines will not be perfect and may not even prevent you catching it— there are some reports that an “effective” vaccine may be one that reduces symptoms.

Apparently the FDA amended the approval order by adding the within 7 days of onset of symptoms due to the unacceptable number of false positives that were occurring.
