Does A Positive PCR covid test mean you are infectuous?
Right now total lockdowns have just been imposed upon Chicago by the democratic mayor. Under these draconian orders nobody is to leave their homes except for work, school or to get groceries. You are not to have even family members to your house for Thanksgiving. This order is for 30 days effectively canceling Thanksgiving and if extended, Christmas. Gov. Cuomo has also just locked down New York saying "you should not have any family gathering, even Thanksgiving gatherings.". If Joe Biden gets away with the stealing of this election, one of the first things that he promises to do is have a national lockdown. That means that if you aren't living in a democratic state, you will be included in the new repression of businesses and freedoms.
What is the basis of this move toward total lockdowns being imposed everywhere? . . . more cases of covid . . . in other words more people testing positive when taking the covid PCR tests. I have numerous videos on my Covid Gizmoh channel that show that these PCR tests do not test for a covid virus, but genetic material called exosomes . . . which may or not be indicative of one having the covid virus. Anyone having any inflammation, cold or regular flu can test positive for this test. Since we are entering into the beginning of the flu season, it should not be a surprise that there is an increase of positive PCR tests. Any regular flu would show up as a positive covid test inflating the publicized numbers that are intended to stoke fear throughout the nation.
As the article you are about to read atests, the PCR covid test is now being run with a threshold of 40 which allows such minute amounts of a virus that most testing positive don't show any symptoms of sickness and the research is showing, that as many as 9 out of every 10 people testing positive are not infectuous at all. So this publicizing of massive positive covid cases is being used as an excuse for a lockdown that will destroy our economy and cause more deaths than the actual virus. In fact when you consider that most normal deaths are fraudulently being labeled covid deaths, subtracting a substantial number of deaths from the well publicized death counts . . . the number of deaths from the lockdown will far surpass those that come from the virus. And the 4 to 6 week national lockdown will for sure kill the economy.
Carefully read the article I post below from the website "Just The News." This article reveals some shocking conclusions about how the PCR covid positive tests coming in are not at all determinative of someone having the covid virus nor does it show they are infectious even if they do have the covid virus.
Growing research indicates many COVID-19 cases might not be infectious at all
Elevated 'cycle thresholds' may be detecting virus long after it is past the point of infection.
A growing body of research suggests that a significant number of confirmed COVID-19 infections in the U.S. — perhaps as many as 9 out of every 10 — may not be infectious at all, with much of the country's testing equipment possibly picking up mere fragments of the disease rather than full-blown infections.
Confirmed cases of the disease have been the focal point of public health authorities and governments worldwide for many months, with countries across the globe working frantically to shore up their testing infrastructure and ensure that most citizens who want a COVID-19 test can obtain one with relative ease.
Many politicians, meanwhile — including most state governors in the U.S. — have tied reopening policies to the number of cases detected in the local community, with regions and localities often being permitted to reopen in staggered "phases" only when they have reached successively lower benchmarks of average new daily cases in the area.
Numerous institutions, meanwhile, have adopted testing protocols in an attempt to preempt the spread of the virus. American colleges and universities, for instance, have turned to mass testing in order to closely monitor incidences of the disease among students, particularly residential students living on campus.
Yet a burgeoning line of scientific inquiry suggests that many confirmed infections of COVID-19 may actually be just residual traces of the virus itself, a contention that — if true — may suggest both that current high levels of positive viruses are clinically insignificant and that the mitigation measures used to suppress them may be excessive.
'Cycle threshold' set very high for many tests
At issue is the method by which many COVID-19 tests detect a patient's viral load within a given sample. Polymerase chain reaction tests (PCR tests), which have been widely deployed to determine if individuals are infected with the disease, function by amplifying DNA samples to the point that an antigen can be detected and classified.
The "cycle threshold" is the number of amplification cycles a PCR test goes through before a target pathogen is detected. A lower cycle threshold means that a higher amount of the virus was present in the sample; a higher threshold means the machine had to work harder to detect the virus in the sample, indicating a lower viral load and more likely a non-infectious patient.
"I'm shocked that people would think that 40 could represent a positive," Juliet Morrison, a virology professor at the University of California, Riverside, told the New York Times in August.
Health authorities elsewhere have indicated similar skepticism of high-threshold tests. A spokeswoman for Taiwan's Central Epidemic Command Center said in June that the agency only assigns positive cases to samples with Cts of 35 or less, with authorities there believing that any samples with Cts of more than 32 are likely (though not definitely) non-infectious.
A team of researchers at Oxford, meanwhile, wrote in a preprint paper last week that, based on a review of various sample collections, swabs requiring more than 30 cycles were "associated with non-infectious samples."
Binary positive-negative test results — in which cycle thresholds are not considered — will "result in false positives with segregation of large numbers of people who are no longer infectious and hence not a threat to public health," they wrote.
Preprint papers have not yet been through the peer review process, so their results and conclusions can be changed prior to full publication. Yet several other research projects have indicated similar results. One, published in April by public health authorities out of France, found that "patients with Ct values equal or above 34 do not excrete infectious viral particles."
Similarly, a study out of Ireland seeking to determine "the duration of infectivity" of COVID-19 patients found that, of numerous samples subject to PCR testing, scientists were unable to achieve positive culture growth in any that required more than 34.3 cycles.
Both of those thresholds are notably smaller than the maximum number of cycles instituted by many test manufacturers, suggesting that there may be many nominally positive COVID-19 cases that are innocuous as far as infectiousness and illness are concerned.
Echoing those concerns, researchers at Harvard in May argued that "the Ct value from positive test results, when interpreted in context, can help to refine clinical decision making," and that a cycle threshold of around 34 may be a useful tool for determining when a patient is truly infectious and when he or she is merely carrying remnants of the virus.
Such a policy, if implemented, could have momentous implications for public health policy in the U.S. and elsewhere. Presently, in many industries and at many institutions, a single positive COVID-19 case can result in a complete shutdown of the affected company or university or elementary school, followed by a rush to have everyone tested out of concern that the virus may have spread.
A greater emphasis on the cycle threshold of positive tests may preempt such disruptive policies by signaling which positive test results are truly infectious and which are detecting low viral loads at much less threat of infectivity.
Early indications suggest the number of clinically trivial positive cases in the U.S. might be startlingly high. The New York Times said last month that a review of the cycle thresholds of positive cases in Nevada, New York and Massachusetts indicated that "up to 90 percent of people testing positive carried barely any virus."
Those numbers, if extrapolated nationwide, could suggest that a significant proportion of the mitigation and preparation measures currently in place across the U.S. might be excessive relative to the actual level of infectious cases around the country.
Ultimately it can be difficult to determine the cycle thresholds used at laboratories across the country, making that kind of extrapolation difficult. A spokeswoman for LabCorp — one of the largest clinical laboratory groups in the world — said the company "does not include the CT (cycle threshold) value in result reporting."
"Our CT cutoff is based on extensive validation," she said, "and is within the accepted range to accurately identify individuals currently infected with SARS-CoV-2." The company on its website says it has performed 13.5 million COVID-19 tests, about 15% of the country's total number of tests.
At the Center for Evidence-Based Medicine at Oxford University, researchers stressed last month that "PCR detection of viruses is helpful so long as its limitations are understood;while it detects RNA in minute quantities, caution needs to be applied to the results as it often does not detect infectious virus."
"If this is not understood, PCR results may lead to restrictions for large groups of people who do not present an infection risk," they wrote.
