After reading quite a bit about the testing, it seems like the statement made around here about the Covid tests showing positive results when in the presence of any Coronavirus antibodies is nonsense, a myth that a lot of people are buying into.
For starters, PCR TESTS DO NOT TEST FOR ANTIBODIES!
THEY ONLY TEST FOR ACTIVE INFECTIONS!!!
But this is where you really need to pay attention…
Think about it… if there are tests that are coming back negative, do you really think there are people out there that have never had a common-cold-type Coronavirus like HCoV-229E and HCoV-OC43, which were isolated nearly 50 years ago?
Or what about HCoV-NL63 and HCoV-HKU1 which have only recently been identified in the past 15 years or so?
These viruses make up 15-30% of all lower respiratory tract infections each year…
As children we all had them, because they specifically seem to affect children/neonates more than non-elderly adults.
If you think the test is detecting ANY CoV, then you are insinuating that the portion of patients on which the 3,572,257 test were performed yet came out negative (709,735 positive tests as of 4/16) HAVE NEVER HAD A CORONAVIRUS TYPE COLD!
YOU ARE SAYING THAT 1 out of 5 people tested NEVER had the common-cold that comes from a Coronavirus in their entire lives!
But, but, we ALL have coronaviruses, right?
Additionally, if any of the tests we have for the afforementioned previously isolated Coronaviruses work in the same manner being proposed, i.e. one test detects ALL CoV’s… then why the hell didn’t they use those or even the tests for SARS-CoV-1 or MERS-CoV?
Why bother isolating the genome of SARS-CoV-2 at all?
Simple logic.
Sorry, I had to get that off my chest because the stupidity behind such an assertion is almost mind numbing.
