As long as some of us are sheltering in place I thought that IST should help spread information to as many as I can….there is lots of info flying around the web…..
I have read and heard a lot about the origins of Covid-19 as that of animals….most notably the Pangolins of Asia……but is that true or just another wild conspiracy?
Maybe not so fast on that conspiracy…….
Pangolins can harbor coronaviruses related to the new coronavirus, a study finds.
Scientists studied viruses in pangolins (Manis javanica) captured in anti-smuggling activities in southern China. The identified coronaviruses, however, are different enough from SARS-CoV-2, the virus that causes COVID-19, to hint that pangolins were not directly responsible for transmitting the virus to people, which had been suggested.
One of the pangolin viruses does have a structure that closely resembles the new coronavirus’ spike protein, which allows the pathogen to get into cells, infectious disease researcher Tommy Tsan-Yuk Lam of the School of Public Health at the University of Hong Kong and colleagues report March 26 in Nature.
The closest relative of SARS-CoV-2 is still from a bat, the only other known mammal found to be infected with similar coronaviruses.
There’s no evidence the coronavirus jumped from pangolins to people
In another story I have heard it is a bat’s fault that viruses are spread…if so why is that?
While people across the world were celebrating the holidays with loved ones at the end of last year, somewhere in China the coronavirus pandemic began with a virus moving from bats to pigs and, ultimately, to the first human.
The rest, as they say, is history. Or at least it will be when the final chapter of the great COVID-19 pandemic of 2020 is written.
But why are bats so often behind viruses that sweep across the globe and kill so many of us?
Why Do Pandemics Often Start With Bats?
There is a report that this virus may have been around for years…..
Scientists studying the origins of the coronavirus have found similar strains in bats and pangolins, leading to speculation that it jumped from one or perhaps both of those animals to humans earlier this year. But a new study floats a different idea: that the virus was spreading in humans for years, undetected and growing ever more dangerous, reports Science Alert. Under this scenario, the virus would have passed from animals to humans a while back, but it would have been harmless to us at the time. “Then, as a result of gradual evolutionary changes over years or perhaps decades, the virus eventually gained the ability to spread from human to human and cause serious, often life-threatening disease,” writes National Institutes of Health chief Francis Collins at his blog. Collins was not involved with the study by US, UK, and Australian researchers in Nature Medicine.
The scientists found that while strains found in bats and pangolins were indeed similar to SARS-CoV-2, the strain causing the current pandemic, the gap between the animal and humans versions remains too large, per the South China Morning Post. (The human strain has a genetic mutation that makes it particularly lethal for us, and the SCMP goes into detail on that.) It’s possible that a closer version in animals exists and just hasn’t been found yet, but the researchers suggest it’s more likely that the strain mutated within humans as it slowly spread. Among other things, that raises the possibility the disease did not originate in Wuhan, China, where the first cases were detected. Another key component of the study: The researchers say it’s all but impossible that the coronavirus originated in a lab—it has all the hallmarks of a natural origin.
Just a little more information for my readers…….I like to be FYI as often as I can especially now when we are all become hermits and a bit of a recluse.
