Researchers tested the workers who had come in close contact with the infected pigs and were relieved to discover the virus was not transmissible to humans — this time. 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 … 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. 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. So nice to read an article like this. The 2003 outbreak of SARS was eventually traced to horseshoe bats in a cave in the Yunnan province of China, confirmed by a 2017 paper published in the … That knowledge, in turn, can inform prevention strategies. While they do carry zoonotic viruses, they are critical for a well-balanced ecosystem. But then something strange happened. In Guangdong, the disease struck newborn piglets the hardest. In Guangdong province, the next step was finding out where the novel coronavirus had come from. Visit our corporate site. To The Bat Cave In Guangdong province, the next step was finding out where the novel coronavirus had come from. Can science 'prove' there's an afterlife? The story of how the novel coronavirus ... laboratory in Wuhan might have spread a deadly bat virus that had been collected for scientific study. The immediate progenitor … Live Science is part of Future US Inc, an international media group and leading digital publisher. In his novel, Koontz described “Wuhan-400” as “China’s most important and dangerous: new biological weapon in a decade”. he says. Merriam, Florence A. 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. Jeanna Bryner - Live Science Editor-in-Chief Researchers began looking for another cause of the piglets' illness. "Based on no data, but simply [a] likely scenario is that the virus went from bats to some mammalian species, currently unknown despite speculation, [and] spilled over to humans," said Gerald Keusch, associate director of the Boston University National Emerging Infectious Diseases Laboratories. Several experts have said to Live Science and other media outlets have reported that the likeliest scenario is that SARS-CoV-2 is naturally occurring. 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. The head of the lab's bat-coronavirus research, Shi Zhengli, published research on Nov. 30, 2017 in the journal PLOS Pathogens that traced the SARS coronavirus pandemic in 2003 to a single population of horseshoe bats in a remote cave in Yunnan province. 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. Then there is the allegation of an accidental release of a natural virus from a lab. And there are currently no vaccines against any coronavirus strains. 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 ). Researchers say the overwhelming evidence indicates this is a natural-borne virus that emerged from an animal host, likely a bat, and was not engineered by humans. (SARS-CoV-2 would require a BSL-3 or higher, according to the Centers for Disease Control and Prevention.) Among the theories circulating: That SARS-CoV-2 arose naturally, after passing from bats to a secondary animal and then to humans; that it was deliberately engineered and then accidentally released by humans; or that researchers were studying a naturally-occurring virus that subsequently escaped from a high-security biolab, the Wuhan Institute of Virology (WIV) in China. It is a man-made virus created in the lab." 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. For this reason, it's really important to know which coronaviruses were being studied at WIV.

The CCP's Document 3 (the CCP playbook on hiding this virus from the world) commanded all researches to destroy the original blood work I am sure the CCP is currently "cleansing" the labs. Simon Anthony is a virologist at Columbia University in New York City and lead author of a 2017 study on bats as a major animal reservoir for coronaviruses around the world. 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. The answer hangs upside-down and lives in caves: Bats. Just today (April 18), the vice director of WIV Zhiming Yuan CGTN, the Chinese state broadcaster, said "there is no way this virus came from us," NBC News reported. None of the bat viruses are close enough to the novel coronavirus to suggest that it jumped from bats to humans. You will receive a verification email shortly. xPacifica /Getty Images The ccp has got to go!!!!!!!!! (Here's where the life a disease researcher can get a bit unusual: the samples came from swabbing the butts of bats.) Zhengli and her colleagues stressed the importance of monitoring and studying the SARS coronaviruses to help prevent another pandemic. Tell Me Another Story: The Book of Story Programs (English) (as Author) Wonder Stories: The Best Myths for Boys and Girls (English) (as Author) Bailey, Cyril, 1871-1957. "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. NY 10036. https://www.wattpad.com/story/185804295-chinese-bl-novel-recommendations Helen’s recount of Bing’s life, from misery and poverty in war-torn China, to her narrow escape from Shanghai and her turbulent start in America, is a heart-wrenching but majestically loving tribute to her mother. Where did SARS-CoV-2 come from? That is the CDC needs full access to the level 2 and level 4 labs in Wuhan. 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 ). The idea was to look at the potential of coronaviruses circulating in bat populations to infect humans. The disease keeps spreading because people won’t stop eating bat soup! Please deactivate your ad blocker in order to see our subscription offer. It was a brand-new disease. But, given the number of coronaviruses that have now spread from animals to people, he adds, "it seems a safe bet to think it will happen again. 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. Related: 28 devastating infectious diseases. Future US, Inc. 11 West 42nd Street, 15th Floor, But, he added, "the level of genome sequence divergence between SARS-CoV-2 and RaTG13 is equivalent to an average of 50 years (and at least 20 years) of evolutionary change." None of this can show the provenance of SARS-CoV-2. 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. The bats in caves nearby, however, likely still harbor the virus — and other unknown coronaviruses — and they're still flying over farms at night. 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. "No matter the origin, evolution in nature and spillover to humans, accidental release from a lab, or deliberate release or genetic manipulation of a pathogen in the lab the way you develop countermeasures is the same," Keusch told Live Science. 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. 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). These alphabet-soup viruses all belong to the same family: the coronavirus. hide caption. And British geneticists trace the earliest cases to September or October, based on the mutation level between different strains (https://www.dailymail.co.uk/news/article-8231753/Coronavirus-started-spreading-early-September-not-originated-Wuhan.html ). The Wuhan lab does work with the closest known relative of SARS-CoV-2, which is a bat coronavirus called RaTG13, evolutionary virologist Edward Holmes, of the Charles Perkins Center and the Marie Bashir Institute for Infectious Diseases and Biosecurity at the University of Sydney, said in a statement from the Australian Media Center. The first known outbreak of SARS-CoV-2 in humans occurred in Wuhan and initially was traced to a wet seafood market (which sold live fish and other animals), though some of the earliest cases have no link to that market, according to research published Feb. 15 in the journal The Lancet. The Wuhan Institute of Virology (scientists pictured) did experiments on bats captured more in Yunnan. The complex narrative switches from the initial perspective of … For example: some bats eat mosquitoes, which also carry dangerous viruses like malaria, yellow fever, chikungunya, Zika and more. These types of labs do spur concerns among some scientists who worry about the risks involved and the potential impact on public health if anything were to go wrong, Nature News reported. This spillover event may have happened before the virus found its way into a live animal market, "which then acted as an amplifying setting with many more infections that subsequently spread and the rest is history," Keusch said. The head of the lab at WIV, for her part, has emphatically denied any link to the institute. When she first was alerted to the viral outbreak in Wuhan on the night of Dec. 30, 2019, Zhengli immediately put her lab to work sequencing the genomes of SARS-CoV-2 from infected patients and comparing the results with records of coronavirus experiments in her lab. Before it was halted in 2004, SARS spread to 33 countries and sickened more than 8,000 people, killing 774. 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. Several ideas have been put forward from natural-borne in bats, an escape from a lab in Wuhan and others. It is possible that they isolated a virus that they were unaware of. They are particularly frightening because they are usually spread by coughing or sneezing; they're airborne, which means they can disseminate easily and quickly. She also looked for any mishandling of viral material used in any experiments, Scientific American reported. 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. Anthony adds an important concern: "Bats are super important!" 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. But the response to develop what is needed to respond, control and eliminate the outbreak remains the same.". The SADS virus in the Chinese pigs affected the gastrointestinal tract. "During interactions with scientists at the WIV laboratory, they noted the new lab has a serious shortage of appropriately trained technicians and investigators needed to safely operate this high-containment laboratory," the officials said in their cable dated to Jan. 19, 2018. At times Mr. Stoker almost succeeds in creating the sense of possibility in impossibility." What's more, despite several proposed candidates, from snakes to pangolins to dogs, researchers have failed to find a clear "intermediate host" — an animal that would have served as a springboard for SARS-CoV-2 to jump from bats to humans. Incidentally, there is an article out that links bats from caves in Yunan province to the Wuhan lab. That's why they scare virologists more than Ebola. A single bat specimen may have had multiple strains. 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. --Atheneum (June 26th, 1897) "The audacity and horror of Dracula are Mr. Stoker's own. I was pretty sure I wasn't going to get this kind of straight talk from the Washington press corps. Plot. By 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. "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. And, at first, the tests did come back positive for PEDV. 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 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. Here's the murky origin story of the novel … "I had not slept a wink for days.". That's because it's impossible to definitively tell whether SARS-CoV-2 emerged from a lab or from nature based on genetics alone. He also wrote it was developed by labs outside of the city of Wuhan. On one farm in February 2017 alone, 64 percent of all newborn piglets died. 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. 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. OFFER: Save 45% on 'How It Works' 'All About Space' and 'All About History'! A team led by Shi Zheng-Li, a coronavirus specialist at the Wuhan Institute of Virology, reported on 23 January on bioRxiv that 2019-nCoV’s sequence was 96.2% similar to a bat … 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. Piglets suckling on a farm in Guangdong province in southeast China, where the virus struck. Though we may never get a definitive answer, at least in the near-term, some say it doesn't matter. Zhengli and another colleague, Peng Zhou, did not reply to a Live Science email requesting comment. "Since one can never say 100% for anything, I think we always need to be aware of all possibilities in order to contravene. Related: 13 coronavirus myths busted by science. These are called adventitious agents and they can contaminate cell lines and animal models without knowledge. Simon Wain-Hobson, a virologist at the Pasteur Institute in Paris, was one of those scientists. Most coronaviruses are mild to moderate infections, but some types are severe and deadly. We need to look at the bats they where using and what experiments they were up to. They're widely distributed, highly diverse, evolve rapidly and adapt easily to new hosts. In early February, Chinese researchers published an article in Nature -- a top science journal -- that concluded the "2019-nCoV is 96% identical at the whole-genome level to a bat … Netflix documentary says yes. The Story of China, written and presented by historian Michael Wood, explores the history of the world’s oldest continuous state, from the ancient past to the present day. (Both SARS and SARS-CoV-2 use the ACE2 receptor as the entry point into cells.). They named it SADS, or swine acute diarrhea syndrome. "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.". Related: 20 of the worst epidemics and pandemics in history. When reports of the coronavirus first popped up in China, the U.S. Deputy National Security Advisor Matthew Pottinger reportedly suspected a potential link to China labs. They found that a key part of SARS-CoV-2, the spike protein that the virus uses to attach to ACE2 receptors on the outsides of human cells, would almost certainly have emerged in nature and not as a lab creation. Is interaction between bats and humans that damn prevalent to where this is even necessary? "This origin story is not currently supported at all by the available data," said Adam Lauring, an associate professor of microbiology, immunology and infectious diseases at the University of Michigan Medical School. "It really comes down to what was in the lab," Greninger told Live Science. It had infected the piglets during an outbreak of PEDV, and then it rapidly took over; by May 2017, more than 24,000 piglets had died. WIV was not immune to those concerns.
