Ping!
Can we ditch the damn masks now and reopened our tattered economy?
Duh...
There’s some truth here, but -as usual- the media distorts it beyond use.
In sum, PCR tests are very good for diagnoses, followed by medical investigation and treatment. Note that that medical investigation and treatment usually starts with isolation and waiting for symptoms.
The PCR tests are NOT GOOD for the public health use of tracking and controlling the outbreak.
They’re too sensitive and slow.
Less sensitive and much quicker ‘rapid tests’ are the tool for public health purposes.
Your choice of tools depends on what you want to accomplish!
Reports are that the FDA is holding up the use of rapid tests by making unreasonable demands for approval.
I'm really sick and tired of "experts".
I don’t think tests can be too sensitive.
But it’s good to know the dynamics of the infection.
No kidding.
What a surprise.
The more the narrative about COVID keeps falling apart, the worse the dems look for keeping the lockdowns going.
Hmmmm... Between this and the CDC’s recent report this pandemic narrative sure is falling apart. I wonder if the Dems are seeing via polling that the public is turning against this nonsense?
This has always been political not medicinal.
DUUUHHHH...!

COVID “1984” THE REAL NUMBERS

ORWELL WOULD BE SO PLEASED!
When can we get rid if these dang masks?!!
However wearing a mask will help concentrate any virus particles present
“Health experts say PCR testing - the most widely used diagnostic test for COVID-19 in the US - are too sensitive and need to be adjusted to rule out people who have insignificant amounts of the virus in their systems because they’re likely not contagious.”
Maybe there is some sanity in the midst of all of the idiocy that is being fomented on us.
The inventor of PCT said, in an interview a few weeks ago, that it is not meant to be a diagnostic test, and should not be used as such. In fact, none of the PCR tests for covid have been validated to FDA standards. None. Zero. Zip.
They would fail validation because of high Error Of Measurement (EOM) rates. Somthey don’t even try. Why not? Well, the FDA gave everyone waivers to use them anyway. For real.
Like any toxin, alive or dead, it’s the dose that kills. A couple virus particles won’t kill anyone. Even bubble-boy can fight off a couple. You need a high enough number to overwhelm your immune system in it’s current state.
The PCR test amplifies whatever virus or dead virus particles it finds, over and over, each cycle roughly doubles them. So yeah, given enough cycles, it could show positive for a single dead virus particle leftover from weeks ago. The CDC says so.

Where the cutoff is is important. How many cycles do you run? How many times is enough? Enough to be sick, infect someone, should be the cutoff, not a gazillion cycles. As I said it’s not meant to be a diagnostic test in the first place. There is no standard of cycles, or even reagents across countries.
Didier Raoault did a study in April, said cutoff should be around 32 cycles. Some labs do 40, for real. All those results from those labs are meaningless.

Wow. Months behind what was obvious when they came out.
