Coronavirus Variants Have No Where to Hide?
The Atlantic piece is selling the PCR tests as precise.. Sure it can detect fragments of a family of viruses (as you will read) But that detection isn't all that meaningful. Other then to sell the idea of a pandemic. The Atlantic oped is also more fear porn. As tiresome as that can be to consider.
For most of the pandemic, that exactness has been a major asset for the hundreds of tests that detect SARS-CoV-2. But the discerning nature of most tests has also opened up a weak point for the coronavirus to exploit. With the virus mutating into new and concerning variants, a few of the tests designed to recognize its original iteration are now getting duped. What was once a singular target has split itself off into many, many bull’s-eyes, each a little different from the next, and we’re having trouble taking aim.
This isn’t yet a crisis, and perhaps it never will be. Most tests are still performing very well against all known versions of the coronavirus, and researchers have work-arounds that will buttress others against the virus’s shape-shifting. But keeping tabs on test performance is crucial, especially while the pandemic rages on in many parts of the world.
“From a global perspective, it’s absolutely necessary to do what we can to make sure we have a good grip on the virus and its mutations,” Neha Agarwal, the associate director of the PATH Diagnostics Program, an organization that has been tracking SARS-CoV-2 tests, told me. As long as it has hosts to infect, the coronavirus will continue to rejigger its genes, (nothing new in the world of viruses) which means that test manufacturers will need to closely track the virus’s movements and tailor their products to follow it. More than a year out from the time when experts first got eyes on the virus, tests are in need of a touch-up.
Most of the coronavirus tests deployed in the United States detect specific stretches of RNA, the genetic material of the virus’s genome, usually chosen because they’re unique to SARS-CoV-2 (or at least the virus family it’s in).
What? Wait just a minute!
Most of the coronavirus tests deployed in the United States detect specific stretches of RNA, the genetic material of the virus’s genome, usually chosen because they’re unique to SARS-CoV-2 (or at least the virus family it’s in).We know that coronavirus is an entire family of viruses that circulate regularly... so what is the test exactly testing for. Stretches of RNA, unique to Sars-CoV-2 (or the virus family it's in)???
"Coronaviruses are a large family of viruses that usually cause mild to moderate upper-respiratory tract illnesses, like the common cold.
When the tests fail, it’s because they’re picky. These molecular tests search the genomic manuscript with about as much precision as the Ctrl+F function on a computer, which means that even single-letter typos—that is, simple RNA mutations—can discombobulate them.
For that reason, many of the experts I talked with are pinning their hopes on the molecular approach to keep testing going as the coronavirus continues to splinter into new lineages. Now that scientists are clued in to the many distinctive patterns that certain variants produce on molecular tests, they’re using them as quick, preliminary screens to tease apart different versions of the virus. When the TaqPath picks up two familiar genes but fails to detect S, for example, researchers may flag the specimen as an Alpha candidate.
Question: Is bad testing leading to the perception of variants existing? Because this is all based on bad testing. When the test picks up to familiar genes but fails to detect another one they MAY flag the specimen?
Still, experts stressed that standard coronavirus tests aren’t a reliable way to fully vet variants, which can be done only by sequencing the pathogen’s entire genome.
I'm seeing a contradiction
detect specific stretches of RNA, the genetic material of the virus’s genome, usually chosen because they’re unique to SARS-CoV-2 (or at least the virus family it’s in).
If the test picks up RNA from the family of coronaviruses- what would the need be to sequence the entire genome? Vaccine pushing? Imagine a vaccine for each alleged variation? It's a marketing dream. Again is bad testing leading to the perception of variants existing? And if testing is not reliable why do we get the endless variant fear porn?
“The more targets there are, the more resilient the test is against changes,” Melissa Miller, the director of the clinical-microbiology laboratory at the University of North Carolina’s School of Medicine, told me."Does that read to you as if every coronavirus will be used to create a pandemic mind set?
“The coronavirus has infected more than 170 million people around the world, and will be with us for some time yet”The coronavirus has always been with us. It’s not new.
“But experts assured me that researchers and companies are keeping close watch, tracking the virus’s many modifications and ensuring that tests are still up to snuff, similar to what’s been done for years with the flu. “
That’s not reassuring. Flu tracking has always been a gamble. A losing gamble. Year after year. With largely ineffective vaccines being produced.
Oh, I get it now! Same pharma profit scam. Different virus.
