Why Was My Rapid Flu Test Negative?The rapid flu tests that most healthcare providers use are a great tool, but they can be wrong. Accuracy can range anywhere from 50 to 90 percent, depending on the test and prevalence of the flu in the community.
I think the inherent problem in all of this is the unreliability of the tests.
Read that blurb I posted about Rachel. She underwent extensive testing. She had to take another test before entering Israel. The same will be said of that man who has gotten it again.
So it seems to be nobody has a handle on when you can be shedding the virus.
They clearly were cleared to come into Israel. So the choice is the guy was weakened and got it again from someone else
Or he still had it even though he tested negative and it flared up again. In the meantime, he could be shedding the virus all over the place
I dont have the answer.
But what we do know is that you can be considered recovered...test negative..and get it again and have symptoms.
