did covid come from a pangolin

That means, before reaching humans, the virus could have passed from bats to the pangolin, the most illegally traded animal in the world. TUESDAY, June 2, 2020 -- Armadillo-like animals called pangolins may have played a role in the emergence in humans of the new SARS -CoV-2 coronavirus, but they weren't the only links in animal-to-human transmission, scientists say. On Feb. 7, researchers in China suggested it might (might!) "Based … In January 2019, nine tons of pangolin scales — thought to have come from some 14,000 animals — were seized in a single shipment in Hong Kong. It was carrying a virus strain almost identical to the form of coronavirus … Answers could stop such a calamity from happening again. Also, last Saturday was World Pangolin Day. Though the research uncovered that the bat coronavirus, known as RaTG13, could not bind with receptors in humans or pangolins, and that the pangolin coronavirus was able to bind to pangolin and human receptors, it still doesn't confirm whether the pangolin virus was a part of SARS-CoV-2's evolution to humans. ‘Machiavellian’ Photo Illustration by The Daily Beast/Getty. By far the most likely explanation is that the virus jumped from bats to humans, perhaps via another animal such as a pangolin, at a wet market in Wuhan (see article). While the research is still inconclusive, COVID-19 did originate from an animal at some point, and the most plausible explanation is that COVID-19 had two or more animal hosts. Read more: Coronavirus, cold or flu? However, the similarity of the strains does suggest the nation's pangolin market is a time bomb that needs to be defused. And pangolins -- which some credit with playing a role in the emergence of the new coronavirus -- might hold clues to fighting COVID-19. Spoiler: The virus seems to combine the backbone from a known bat virus genome with a spike protein (the part that binds to a target cell) from a pangolin virus. But the similarity to pangolin coronaviruses is a huge health risk for the human population. Study co-author Donald Benton said, "We still don't have evidence to confirm the evolutionary path of SARS-CoV-2 or to prove definitively that … Emergence of SARS-CoV-2 (the virus that causes COVID-19) through recombination and strong purifying selection.. A combination of genetic shuffling and evolutionary selection of near-identical genetic sequences among specific bat and pangolin coronaviruses may have led to the evolution of SARS-CoV-2 and its introduction into humans, a new study suggests. In 2013, scientists captured a wild horseshoe bat in a remote cave in Yunnan province, 1,700km southwest of Wuhan. Answers could stop such a calamity from happening again. Selling the scales, which are made of the same stuff as your fingernails, is illegal, but it took an American journalist less than an hour to track them down in a market in China armed with a scrap of paper that said “pangolin scales” in Chinese. Contributor Group. A pangolin is a small mammal covered in sharp plates—a sort-of pinecone with legs and a tongue, an army tank that triggers a cuddle reflex.

Two … Researchers have also found that SARS-CoV-2-related coronaviruses in pangolins — or scaly anteaters— share genetic material with the virus causing COVID-19, but we won’t know for certain which species were involved in spillover of this virus until more research is done. The team is continuing their research on the SARS-CoV-2 spikes and related coronaviruses. Drafted: 16 March 2020 In the segment below, I tell two stories of how this might have occurred, one as leak from an American lab and one from a Chinese lab. Researchers have found that three quarters of new diseases come from animals. One day, the parasite—an ancestor of the coronavirus, SARS -CoV-2—had an opportunity to expand its realm. Based on the research in our lab, we believe that pangolins, as opposed to snakes, may have served as the hosts that transmitted the coronavirus to people and caused the ongoing COVID-19 pandemic. (Why are animals that eat termites often very cute? Did Covid-19 Come From A Lab? The real blame for the new coronavirus lies with humans for destroying habitats and therefore upping the contact we have with a roulette of animal germs, argued Pandemic author Sonia Shah—not with pangolins or bats or snakes or any other animal that may have spread the new coronavirus. Pangolins are the most trafficked mammal on the planet, according to National Geographic. These two animals share no common habitat, so it is possible but unlikely that they could have combined in nature. Mark Kortepeter.

Here is a lion trying—and failing—to eat a mighty curled-up pangolin. But some theories suggest that pangolins may be the source of the novel coronavirus. A 99% DNA match This is because every time a virus replicates, its genes can mutate and make it possible to spread from animals to people. Possibilities also include that it originated from an unknown bat coronavirus that could infect pangolins and then moved into humans, the study authors noted. It may be that RaTG13 or a similar bat coronavirus merged with a coronavirus in a species other than a pangolin. The next month, 33 tons of pangolin … Ever since the nexus for the outbreak of COVID-19 was traced back to a wet market in Hubei province, the search has been on to determine the virus's heritage. Either way, pangolins have a friend in Prince William, who is on camera here explaining that they might be extinct “before most people have even heard of them.” Great excuse to talk more about pangolins. The World Is Drowning in Plastic Waste. The authors don’t conclude that the virus causing the Covid-19 pandemic came from pangolins, but they say that since pangolins carry such similar viruses, they are at a risk of transmitting even more viruses to humans. One day, the parasite—an ancestor of the coronavirus, SARS -CoV-2—had an opportunity to expand its realm. In 2013, scientists captured a wild horseshoe bat in a remote cave in Yunnan province, 1,700km southwest of Wuhan.

Possibilities also include that it originated from an unknown bat coronavirus that could infect pangolins and then moved into humans, the study authors noted. Conservationist Jonathan Kolby warned that “rumors” of their connection to the outbreak could fuel racist (and ridiculous) narratives related to traditional medicine. According to Steve Gamblin, group leader of the Structural Biology of Disease Processes Laboratory, "A lot is still to be uncovered about the evolution of SARS-CoV-2, but the more we know about its history and which species it passed through, the more we understand about how it works, and how it may continue to evolve.". A lab worker studying bat viruses who slipped up and sniffed the air under her biosafety hood. Some adult pangolins weigh as little as chihuahuas, some as much as golden retrievers.
