I'll post this as a separate thread because I think it's very imporant and I've seen no-one talking about it apart from Canadian biologist David Crowe of Infectious Myth. It's the only logical explanation that I can think of for why China has had hardly any new coronavirus cases since March 2020.
Note here that only China requires other criteria besides a positive PCR test for a diagnosis of covid-19: "The Chinese Centers for Disease Control and Prevention requires clinical manifestations and usually exposure history in addition to a positive PCR result to confirm a case.”
David Crowe wrote about when China changed diagnostic criteria here: "The Chinese eventually woke up and, around February 16th required confirmed cases to meet the requirements for a suspected case, as well as a positive test. They may have put this new definition into practice earlier because after a massive addition of almost 16,000 confirmed cases on February 12th, the number fell dramatically each day and, by February 18th was under 500 cases, and continued to stay low."
Here you can see the amazing drop that occurred in China after the change in diagnostic criteria:
By now it is getting clear that David was right - while all other countries are battling a "second wave", China still has no increase in cases because their definition of a confirmed case requires both a reasonable possibility of contact with a previous case, and symptoms, and that allowed the epidemic to burn out. Once everyone is quarantined, contact with an existing case is highly unlikely, testing stops and doctors can declare victory.
On the other hand, covid-19 epidemic in most other countries is allowed to grow and never end due to exclusive reliance on faulty PCR tests (and as this article explains, such loose diagnostic criteria was never used before).
And before anyone goes on to say it is due to their authoritarian government's strict measures, habitual wearing of masks and so on, please have a look at the pictures below from Wuhan this summer...
