Testing errors – People who have recovered still test positive
Tests can’t distinguish between live virus & dead matter. They “falsely identified dead viral matter as active COVID-19 infection.” Recovered patients who tested positive again were not due to reinfection or reactivation but, rather, to testing errors.
A team of South Korean infectious disease researchers has concluded that patients who have recovered from COVID-19 and subsequently tested positive again for SARS-CoV-2 were not due to reinfection or reactivation but, rather, to testing errors.
According to Dr. Oh Myoung-don, MD, head of Seoul National University Hospital’s division of infectious diseases, the PCR (polymerase chain reaction) tests used to determine the presence of the SARS-CoV-2 virus and help diagnose cases of COVID-19 cannot distinguish between the virus and harmless fragments of the virus.
Vaccine developer Seol Dai-wu of Chung-Ang University in Seoul, South Korea agrees. “The RT-PCR machine itself cannot distinguish an infectious viral particle versus a non-infectious virus particle, as the test simply detects any viral component,” Seol said.
You have won the fight, you’re immune. But the test cannot discriminate.
As immunologist Beda Stadler, PhD, former director of the University Institute of Immunology at the Insel Hospital in Bern, Switzerland notes, people who recovered from COVID-19 can still test positive for SARS-CoV-2 because…
… the coronavirus test measures only a very tiny tiny piece of the genome of the virus, and if your immune cells have killed the virus, then you have debris, you have rotten pieces of the nucleic acids in your blood and everywhere, and the assay can pick up these rotten pieces and then it look like as if you’re infected. You’re not. You have won the fight, you’re immune. So [the test] cannot discriminate.
The findings by Dr. Oh and his research team have been confirmed by the Korean Centers for Disease Control and Prevention (KCDC). The KCDC studied 285 cases of patients who had recovered and later tested positive again for the virus. Despite the positive tests, the agency determined that the patients were not contagious because they did not actually have the virus—that the PCR tests has “falsely identified dead viral matter as active COVID-19 infection.”
People now allowed to go back to work or school
The new research has led to new protocols for handling cases involving people who recovered from COVID-19. Now in South Korea, even if they retested positive, there is no longer a requirement for people who have recovered from COVID-19 and gone through isolation, to test negative for SARS-CoV-2 before going back to work or school.
