Last month, South Korean scientists made a very disturbing discovery. About 15 percent of patients who had recovered from the coronavirus was testing positive again. The same worrying phenomenon was discovered in China as well.
The implications were disheartening. It meant that a large percentage of people may never become immune from the coronavirus, making an effective vaccine very difficult to create.
But South Korean scientists kept investigating and have now found that it’s likely what the testing of coronavirus patients was detecting were “non-infectious” pieces of the virus that were causing the tests to register positive.
South Korea uses a very sensitive test for the virus — an “RT-PCR” test — which detects the virus in genetic materials.
But in some cases, the tests may detect old particles of the virus, which may no longer pose a significant threat to the patient or others, said Seol Dai-wu, an expert in vaccine development at Seouls Chung-Ang University.
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.
This so-called false positive result is likely behind cases of recovered patients testing positive again, the KCDC says.
Some of those who recovered from the coronavirus were showing respiratory symptoms again within a few weeks. But the testing showed that not only were the patients not suffering from COVID-19, but they also weren’t infectious.
When investigating people who appear to suffer symptoms relapse after recovering from COVID-19, KCDC takes cultures of the virus, a process that takes more than two weeks before reliable results become evident.
All 29 completed culture tests as of Wednesday had come back negative. At least 79 are being processed.
The virus in the relapse cases have little to no infectiousness, Jeong said.

Some viruses like Hepatitis B and HIV are able to live on and constantly reinfect hosts. The coronavirus can apparently not do that, which is good news for the vaccine researchers.
But the coronavirus may not force our immune systems to develop effective antibodies against it. That wouldn’t be good news either.
But scientists don’t know whether people who have been exposed to the coronavirus will be immune for life, as is usually the case for the measles, or if the disease will return again and again, like the common cold.
“This to me is one of the big unanswered questions that we have,” says Jeffrey Shaman, a professor of environmental health sciences at Columbia University, “because it really says, ‘What is the full exit strategy to this and how long are we going to be contending with it?’ “
Just another reason that testing may be meaningless
Time to get over ourselves and get back to work
This is not what the left wanted to hear. They want excuses to keep us locked down until January.
A vaccine is useless if antibodies dont protect us
Stop all the Panic Porn and get back to work
I’ve heard about chronic HBV, but not much about re-infection. If infected with HBV, and the patient fails to produce enough Anti-HBs, it is a sign that they are developing chronic HBV. Not a good thing for one’s long term health.
For my money, ANYTHING coming from NPR is just as authoritative as CNN or the New York Times. Such experts as Anthony Fauci, Bill Gates and Andrew Cuomo have worked to deceive us for months. In February, Fauci’s expert opinion that the virus posed no threat to the US instantly shifted to a projection of 1.6 to 2.2 million deaths. Now we’ve gone from COVID antibodies mysteriously appearing in people who apparently haven’t had it to “the coronavirus may not force our immune systems to develop antibodies.”
Virtually every projection of every model the publicly paraded experts have chosen to use has been wrong by orders of magnitude, from the requirements for hospital beds to the new hotspots. Meanwhile, every dissenting opinion, from people as equally educated and experienced as Fauci, including doctors who’ve treated hundreds of patients, is promptly removed from public view. I’ve had difficulty finding any previous situation, of any context, in which every expert has been so utterly wrong or changed his or her opinion so dramatically.
Rt pcr.. dectactable does not mean infectable. Lots of false pos, esp with si gle target “positive. Criteria. It is the nature of the test method... esp when the specificity has benn tremedously reduced, while sensitivity remains high.
The things the lab has to do to keeo a virus alive long enough for testing, should have been your first clue that detection of a dead viral remanent on cardboard, hair and shoe strings is meaningless. America home of the fearful.
Depending on how long viral particles remain in the blood, this test would probably be a LOT more reliable than testing for antibodies.
I don’t think that the antibodies can reliably distinguish between Covid-19 antigens and other antigens, which would explain the unbelievably high rate of immunity that the antibody tests are showing. Finding traces of Covid-19 in the blood is, IMO, much more reliable and *should* be more indicative of a recent infection.
Old news - shortly after Korea found out about it they stated it was positives from fragments of RNA.

I have said for months that Persistence is not Contagion.
I’ll now add: Detectable is not Infectable.
The persistence on fomites info was walked back a few weeks ago, but the fear was already so inculcated, people were reluctant to believe the positive information.
Good post. Thanx.
