(35,300 posts)They have every reason to want the truth, and none to lie.
They had a large number of cases of people who tested positive for COVID, recovered, and tested positive again. Some had symptoms or some reason to get retested. You see the problem.
Same for some cases in China, elsewhere. What's a pain to do is to test for live virus. But the S. Koreans did this, for their "re-infected" patients. And they found that there wasn't any detectable live virus. That left the PCR test, and they quantified some things and found that the PCR test was very, very sensitive and picking up small trace amounts of RNA. It's a systemic problem with the testing. (It's the same checking for heavy metals. We can get down to fraction of a part per trillion, and that some proposed limits would rule out most of even the purest ground or surface water.)
(The report came out last week, Monday or Tuesday. I posted it here as part of an old thread, but since it didn't fit the DU Zeitgeist.)
The remaining issue is, "What about the symptoms?" Sniffles, dry cough, low fever aren't exactly symptoms unique to COVID.
