So somewhere along its evolutionary path, 2019-nCoV picked up a protein or protein keys that turned the lock to give it access to snakes. The virus has been detected in travelers to Thailand, Japan, South Korea and Taiwan, as well as a who had recently visited Wuhan. The outbreak started late last month in the city of Wuhan in central China, apparently at Huanan Seafood Market. However, how the virus could adapt to both the cold-blooded and warm-blooded hosts remains a mystery. Where animals mix and mingle, so do the viruses the carry. Common symptoms include a runny nose, headache, cough and fever.

The virus can evolve 10. Wuhan, China, a port city of more than 11 million people, is under lock-down as authorities attempt to limit the spread of a mysterious virus. As authorities deliberate over whether the virus is an international public health emergency, scientists think they now know something that will be critical in the fight against the virus' spread — where it came from in the first place. Share Live animal and game markets are not uncommon sources of new viral illnesses that afflict humans although this in itself is an uncommon occurrence. But an expert panel has concluded there have been at least a few cases of people catching it from others, raising the possibility it could spread more widely.

Many Chinese travel abroad for the holiday and a few cases have been confirmed outside the mainland - in South Korea, Japan, Thailand and Taiwan. About 300 cases have been identified. The study also found that, as a result of genetic recombination, 2019-nCoV has a change in one of its viral proteins that recognizes and binds to receptors on host cells. Nonetheless, the reported findings will also provide insights for developing prevention and treatment protocols. After snakes, the second most likely animal reservoir for the new virus are s, although the chances of marmots being to blame are far less likely, the study authors argue. The paper also quoted other merchants as saying trade in wildlife took place up until the market was shuttered for disinfection shortly after the outbreak. Now, a controversial new study points to a slithering suspect: snakes.

In rare cases, coronaviruses in animals can evolve to infect people and then spread between people. Anyone who does have a high temperature or is feeling unwell will be interviewed by officials. The scientists conducted an analysis and compared the genetic sequences of 2019-nCoV and all other known coronaviruses. What species a virus is able to infect depends on what proteins it has on the surfaces of its cells, and whether they can bind to the receptors on the surfaces of other animals' cells. However, researchers not involved in the study questioned the findings. Another man in was also suspected of contracting the disease but was cleared on Wednesday.

They were reported with the onset of an annual travel rush for the Lunar New Year holiday. The source of the virus has been identified as the illegally sold wildlife meat 9. Snakes — the — may be the original source of the that has triggered an outbreak of a deadly infectious respiratory illness in China this winter. It is more difficult for children to contract the virus, the reason remains unknown Source: China's National Health Commission, People's Daily China bans the trafficking of a number of wild species or requires special licences, but regulations are loose for some species if they are commercially farmed. As the situation develops, bigger mysteries remain unsolved: If the snake hypothesis turns out to be correct, scientists how a virus could adapt to both cold-blooded and warm-blooded hosts — or where it might next.

That includes diseases we consider distinctly human, like measles and smallpox. That travel rush is expected to spread the disease more widely. The study authors believe their work likely narrows down the source of the virus from the list of 112 live animals and animal products that were sold at the market that's likely the outbreak's epicenter. Since then, sick travelers from Wuhan have infected people in China and other countries,. Initially, authorities in China said there was no evidence of human-to-human transmission in the present outbreak. Gao Fu, director of the Chinese centre for disease control and prevention, said in Beijing on Wednesday that authorities believe the virus likely came from 'wild animals at the seafood market' though the exact source remains undetermined. Sold alongside a menagerie the included live koalas, rats and wolf pups at the Huanan Seafood Market in central Wuhan - now thought to be the outbreak's epicentre - snakes likely then served as the jumping-off point for the virus to begin infecting humans.
