(Here's where the life a disease researcher can get a bit unusual: the samples came from swabbing the butts of bats.) (SARS-CoV-2 would require a BSL-3 or higher, according to the Centers for Disease Control and Prevention.) For this reason, it's really important to know which coronaviruses were being studied at WIV. The Chinese virology institute at the centre of US allegations it may have been the source of the COVID-19 pandemic has three live strains of bat coronavirus on-site, but none match the new global contagion, its director has said. "Culling bats because of fears they carry dangerous viruses is not the way forward – and this can actually have the opposite effect and increase transmission risk," Anthony cautions. Related: The 12 deadliest viruses on Earth. Live Science senior writer Rachael Rettner contributed to this report. The suspected patient zero, likewise, doesn't seem to be a Wuhan resident (https://www.scmp.com/news/china/society/article/3074991/coronavirus-chinas-first-confirmed-covid-19-case-traced-back ). The Chinese virology institute at the centre of US allegations it may have been the source of the COVID-19 pandemic has three live strains of bat … In 2018, after scientist diplomats from the U.S. embassy in Beijing visited the WIV, they were so concerned by the lack of safety and management at the lab that the diplomats sent two official warnings back to the U.S. One of the official cables, obtained by The Washington Post, suggested that the lab's work on bat coronaviruses with the potential for human transmission could risk causing a new SARS-like pandemic, Post columnist Josh Rogin wrote. If that virus infected a staff member and that person then traveled to the nearby seafood market, the virus could have spread from there, he said. Problem is, the earliest confirmed case was dated to December 1st and was far away from the actual labs (https://www.thelancet.com/journals/lancet/article/PIIS0140-6736(20)30183-5/fulltext ). Zhengli and her colleagues stressed the importance of monitoring and studying the SARS coronaviruses to help prevent another pandemic. That knowledge, in turn, can inform prevention strategies. In Guangdong province, the next step was finding out where the novel coronavirus had come from. Jeanna Bryner - Live Science Editor-in-Chief Piglets suckling on a farm in Guangdong province in southeast China, where the virus struck. The SARS-CoV-2 virus is most closely related to coronaviruses found in certain populations of horseshoe bats that live about 1,000 miles (1,600 kilometers) away in Yunnan province, China. Visit our corporate site. Sequencing of the Covid-19 genome has traced it to bats found in Yunnan's caves. Bats don't just spread SARS and MERS; they can also harbor diseases like Ebola, Hendra, Marburg and Nipah, a virus in Southeast Asia that also spilled over from bats to pigs and then moved on to humans. In his novel, Koontz described “Wuhan-400” as “China’s most important and dangerous: new biological weapon in a decade”. "It really comes down to what was in the lab," Greninger told Live Science. "The timeline is fuzzy and I don't think we have real data to say when these things began, in large part because the data are being held back from inspection," Keusch told Live Science. In that Nature medicine study — one of the strongest rebukes of this idea — Kristian Andersen, an associate professor of immunology and microbiology at Scripps Research, and his colleagues analyzed the genome sequences of SARS-CoV-2 and coronaviruses in animals. Well that's becoming more obvious everyday. In mid-January, according to a New York Times report, Pottinger asked intelligence agencies like the C.I.A., particularly individuals with expertise on Asia and weapons of mass destruction, to investigate this idea. ", "They give us a head start by identifying viruses with the genetic prerequisites for human infection, and viruses in areas where the ecological conditions might facilitate spillover," he says. (Both SARS and SARS-CoV-2 use the ACE2 receptor as the entry point into cells.). That is the CDC needs full access to the level 2 and level 4 labs in Wuhan. Meanwhile, the lab at the center of these speculations had long been sounding the alarm about the risk of the SARS-like coronaviruses they studied to spawn a pandemic. Once researchers got this new virus under the microscope, they confirmed that it was a virus in the same family as both PEDV and SARS — but it wasn't one they'd seen before. While they do carry zoonotic viruses, they are critical for a well-balanced ecosystem. Lauring pointed to a study published March 17 in the journal Nature Medicine, which provided evidence against the idea that the virus was engineered in a lab. OFFER: Save 45% on 'How It Works' 'All About Space' and 'All About History'! Claim: "This virus, COVID-19 SARS-CoV-2 virus, actually is not from nature. COVID-19 is a new disease, caused by a novel (or new) coronavirus that has not previously been seen in humans. Melody Schreiber (@m_scribe on Twitter) is a freelance journalist in Washington, D.C. Animal coronaviruses rarely infect people and then spread between people. But once the farmers separated sick piglets and sows from the rest of the herd, the outbreak abated within a few months. 18 April 2020. The article clearly illustrates how the bat lady of Wuhan would have been able to gain the virus without making it look like gene manipulation. Plot. The idea was to look at the potential of coronaviruses circulating in bat populations to infect humans. It is a man-made virus created in the lab." "Bats have been recognized as one of the most important reservoirs for emerging viruses," the researchers write. And, at first, the tests did come back positive for PEDV. hide caption. What if they didn't? The novel is primarily set in the Northern Song dynasty (960–1127) of China, but its setting also covers the non-Han empires of Liao, Dali, Western Xia and Tibet. For example: some bats eat mosquitoes, which also carry dangerous viruses like malaria, yellow fever, chikungunya, Zika and more. China is not alone. We just don't know which virus it will [be], where it will come from, or when.". Before it was halted in 2004, SARS spread to 33 countries and sickened more than 8,000 people, killing 774. This occurred with two earlier coronaviruses, MERS-CoV and SARS-CoV. Future US, Inc. 11 West 42nd Street, 15th Floor, New York, At the beginning of February, Zhengli sent a note over WeChat to reassure her friends that there was no link, saying "I swear with my life, [the virus] has nothing to do with the lab," the South China Morning Post reported Feb. 6. Anthony adds an important concern: "Bats are super important!" --Atheneum (June 26th, 1897) "The audacity and horror of Dracula are Mr. Stoker's own. The answer hangs upside-down and lives in caves: Bats. "Dracula is highly sensational....An immense amount of energy, a certain degree of imaginative faculty, and many ingenious and gruesome details are there. In Guangdong, the disease struck newborn piglets the hardest. Or, he added, an "inappropriate disposal of waste from the facility" could have infected humans directly or from a susceptible intermediary, such as a stray cat. xPacifica /Getty Images Uncovering the natural source of the coronavirus will likely require large-scale sampling of animals—including bat and human populations—in China to trace the evolution of the novel coronavirus. However, Lauring said that based on the Nature Medicine paper, "the SARS-CoV-2 virus has some key differences in specific genes relative to previously identified coronaviruses — the ones a laboratory would be working with. The plot is made up of separate yet intertwining story lines revolving around three protagonists – Qiao Feng, Duan Yu and Xuzhu – who become sworn brothers in chapter 41. © Live Science is part of Future US Inc, an international media group and leading digital publisher. We need to get into those labs. Though we may never get a definitive answer, at least in the near-term, some say it doesn't matter. And while scientists have gotten to know some of the most intimate details of the virus called SARS-CoV-2, one question has evaded any definitive answers — Where did the virus come from? At times Mr. Stoker almost succeeds in creating the sense of possibility in impossibility." "Because the mutations are acquired randomly by selection, there is no signature of a human gene jockey, but this is clearly a virus still created by human intervention.". So nice to read an article like this. They are particularly frightening because they are usually spread by coughing or sneezing; they're airborne, which means they can disseminate easily and quickly. These questions have led some people to look elsewhere in the hunt for the virus's origin, and some have focused on the Wuhan Institute of Virology (WIV). Labs like these must follow strict safety guidelines that include filtering air, treating water and waste before they exit, and requiring lab personnel to shower and change their clothes before and after entering the facility, Nature News reported in 2017. And I was right. SARS is one such strain; another is MERS (Middle East respiratory syndrome), which was discovered in Saudi Arabia in 2012 and has since killed 640 people. Piglets suckling on a farm in Guangdong province in southeast China, where the virus struck. The researchers also noted that other SARS-like coronaviruses discovered in that cave used the ACE2 receptor to infect cells and could "replicate efficiently in primary human airway cells," they wrote. The ccp has got to go!!!!!!!!! An unprecedented amount of research has been focused solely on understanding the novel coronavirus that has taken nearly 150,000 lives across the globe. In a new study published by Nature on Wednesday, those researchers highlight the possibility of deadly coronavirus transmission from bats to domesticated animals and, in turn, to humans. Moving forward, Shi recommends long-term surveillance for viruses in wildlife. Related: 13 coronavirus myths busted by science. "The result of these experiments is a virus that is highly virulent in humans but is sufficiently different that it no longer resembles the original bat virus," Petrovsky said in a statement from the Australian Media Center. Zhengli Shi, the principle investigator of emerging viruses at the Wuhan Institute of Virology and a co-author on the Nature report, says it appears that China is emerging as a hot spot for the detection of novel viruses. The head of the lab at WIV, for her part, has emphatically denied any link to the institute. By Stay up to date on the coronavirus outbreak by signing up to our newsletter today. The answer hangs upside-down and lives in caves: Bats. The Religion of Ancient Rome (English) (as Author) Bailey, Florence Merriam, 1863-1948. They're widely distributed, highly diverse, evolve rapidly and adapt easily to new hosts. The immediate progenitor … The story of how the novel coronavirus ... laboratory in Wuhan might have spread a deadly bat virus that had been collected for scientific study. "Monitoring bat populations can help people to understand how viruses are transmitted and which regions are at high risk of bat-borne diseases," she says. But then something strange happened. Can science 'prove' there's an afterlife? Initial assessments conducted by the Chinese government pointed to the city's Huanan Seafood Market as the likely cause of a natural outbreak of SARS-CoV-2, a new coronavirus that causes Covid-19. Thank you for signing up to Live Science. Bat coronaviruses can be cultured in lab dishes with cells that have the human ACE2 receptor; over time, the virus will gain adaptations that let it efficiently bind to those receptors. The Wuhan Institute of Virology (scientists pictured) did experiments on bats captured more in Yunnan. That may rule out deliberate genetic engineering, but what about other scenarios that point to bats as the natural hosts, but WIV as the source of the outbreak? Furthermore, the notion that SARS-CoV-2 was genetically engineered is pure conspiracy, experts told Live Science, but it's still impossible to rule out the notion that Chinese scientists were studying a naturally-occurring coronavirus that subsequently "escaped" from the lab. It was a brand-new disease. In that paper, which was published in 2015 in the journal Nature Medicine, they described how they had created a chimeric SARS-like virus out of the surface spike protein of a coronavirus found in horseshoe bats, called SHC014, and the backbone of a SARS virus that could be grown in mice. The novel SARS-CoV-2 coronavirus that emerged in the city of Wuhan, China, last year and has since caused a large scale COVID-19 epidemic and … The bats in caves nearby, however, likely still harbor the virus — and other unknown coronaviruses — and they're still flying over farms at night. I was pretty sure I wasn't going to get this kind of straight talk from the Washington press corps.
