Coronavirus: Five burning questions scientists want to answer

animal coronavirus came from

Coronaviruses are a large family of viruses. This recognition is a key step in allowing the virus to enter cells, and the change in this specific protein may have contributed to 2019-nCoV's ability to hop species, the authors said. The two types of snakes common to southeastern China where the outbreak originated are Bungarus multicinctus, or the many-banded krait, and Naja atra, or the Chinese cobra, the authors said. Seventeen people have so far died after testing positive for the virus. If it turns out that the animals in the market were not the source of the virus, it would mean that researchers are far from closing in on the reservoir for 2019-nCoV.

People carrying the novel coronavirus may only have mild symptoms, such as a sore throat. How long can the virus survive on a hard surface, like a doorknob, or in the air? A good candidate Previously, researchers have noted that coronaviruses are a possible cause of death in pangolins , and that nCoV-2019 and coronaviruses from pangolins use receptors with similar molecular structures to infect cells. By all accounts, the Huanan Seafood Wholesale Market in Wuhan City, where the virus was first detected, fit that description to a tee, with vendors illegally trading in wild and exotic animals alongside the daily ocean catch. To be clear, Hong Kong's Agriculture, Fisheries and Conservation Department is doing further tests to confirm whether or not the dog who was put in quarantine has been infected. Even small supermarkets commonly have fish tanks where shoppers can purchase live seafood. This helps other countries respond quickly to disease outbreaks.

Coronavirus: Why infections from animals are such a deadly problem

Andersen says he has compared publicly available sequences of pangolin viruses and found that they are similar to that of nCoV-2019. Sometimes they have to make decisions without all the answers in hand, or with only partial information. But the first step is to painstakingly reconstruct how a single patient — preferably one of the earliest victims — moved through her life after she was exposed and who among her contacts subsequently came down with the same illness. In rare cases, coronaviruses in animals can evolve to infect people and then spread between people. The disease does not last long in the host body but it does cause considerable pain and abdominal discomfort while active, often leading to death. According to , there have been no cases of dogs or cats being infected with the new coronavirus.

New coronavirus may have 'jumped' to humans from snakes, study finds

While one side of the low-slung warren of stalls did primarily stock fish and shellfish, the other offered a cornucopia of spices, sundries and, if you knew where to look, beavers, porcupines and snakes. Researchers not involved in the study also called for further field and lab work to identify the source of the virus, according to Nature News. The virus's genetic sequencing was released by scientists in China to the rest of the world to enable other countries to quickly diagnose potential new cases. Researchers at Imperial College London maintain that the average Coronavirus-infected individual will pass the virus on to at least two-and-a-half others. Picture via The two types of snakes common to southeastern China are Bungarus multicinctus — the many-banded krait — and Naja atra — Chinese cobra. The quarantine affects more than 50 million people—greater than the population of New York City, London, and Moscow combined.

Map showing the confirmed case of new coronavirus 2019-nCoV. These include Thailand, Australia, South Korea, Japan, Singapore, France, the United States, and Canada. Find similar virus epidemic news on and. The hunt for its sanctuary will take much more sleuthing by epidemiologists, geneticists, physicians and wildlife biologists. Chinese officials are disinfecting whole streets and parks with clouds of gas and chilling footage has emerged of roadside quarantine tents, hastily erected to isolate suspected cases. The virus also causes swelling in the respiratory system, which can make it hard for the lungs to pass oxygen into the bloodstream - leading to organ failure and death. Now, the South China Agricultural University in Guangzhou that two of its researchers, Shen Yongyi and Xiao Lihua, have identified the pangolin as the potential source of nCoV-2019 on the basis of a genetic comparison of coronaviruses taken from the animals and from humans infected in the outbreak and other findings.

That's the best thing you can do for your pet. Origin of the new coronavirus The scientists that 2019-nCoV is a mix of two coronaviruses: one that is known to infect bats and another unknown coronavirus. Sometimes, a germ that wreaks havoc in one country sickens few people in another. A Missing Link While experts first traced the origin of the coronavirus outbreak to the seafood market, a description of the clinical cases published in on Friday puts forth another possibility.

Zhong Nanshan, a Chinese government medical adviser, also identified badgers and rats as possible sources. One man can be heard telling the woman in Mandarin: 'Eat the meat! They considered several potential hosts, including marmots, hedgehogs, bats, birds, humans and snakes. In a statement, the team said: 'The Wuhan coronavirus' natural host could be bats… but between bats and humans there may be an unknown intermediate. Two studies published last week in the medical journal Lancet describe efforts to reconstruct those early contacts among infected people, and use them to make inferences about how 2019-nCoV spreads. However, researchers not involved in the study questioned the findings.
