The direct source of novel coronavirus outbreak

February 17, 2020 / BIOON/ --Recently, researchers from China found that the endangered pangolin may be the "missing link" between bats and humans, but other scientists said that the search work is not over at present; an earlier study pointed to snakes, while there are still many candidate species considered to be the outbreak site in the wild animal market of Wuhan The outbreak of SARS in 2002-2003 involved And another coronavirus, which is transmitted to humans by civets Image source: missing link of mediaexpress.com: pangolin Many animal animal viruses novel coronavirus are transmitted to other species, and almost all the coronavirus strains that infect humans are originated from wild animals Bat is a known new type of coronavirus carrier At present, the virus has infected at least 31 thousand people (reported by news report) and has caused more than 630 deaths worldwide, most of which occurred in China According to a recent genetic study and analysis, the virus strains transmitted in humans are 96% similar to those in bats However, according to the research data of Pasteur Research Institute, the disease may not be directly transmitted to people through bats, and one of the animals may be in the middle link Many studies have shown that the viruses in bats lack the necessary hardware to anchor human cell receptors, but at present, researchers do not know the animals in the middle key link The animal animal animal novel coronavirus may be a mammal or a badger family According to Xinhua reports, the researchers from South China Agricultural University analyzed the samples of more than 1000 wild animals, and found that the virus sequences in pangolin were in a 99% similarity to that of the new coronavirus infected patients, but other experts indicated that they should be It is time to be cautious about this conclusion James wood, a researcher at Cambridge University, said that this may not be scientific evidence, and the investigation of animal hosts is extremely important, but the results may be published later; it is obviously not enough to only report the similarity of virus RNA sequences above 99%; in vain? In order to determine the culprit, researchers need to test every animal on the market Obviously, this is almost impossible, because the South China seafood market in Wuhan has been permanently closed Martine Peeters, a virologist at the French Association for research and development, found that bats may have transmitted the virus to humans Peeters has identified animal hosts that transmit the Ebola virus; he said during the Ebola study, they collected thousands of bats from several places in Africa for research, and of course, Chinese researchers could do the same Why is it important? Novel coronavirus carrying host animal may be very important for future prevention and control of this outbreak, although China may be too late for the outbreak For instance, the Chinese government has banned the sale of civet cats during the SARS epidemic The research can be similar to that of SARS research Years Ebola's research began in 1976, and researchers didn't publish relevant research results until 2005; a decisive factor may be the percentage of the same species infected, if the proportion is very low, for example, less than 1%, it will obviously reduce the individual's chances of being infected How to prevent future outbreaks? The novel coronavirus is only the latest case of human consumption of wild animal with animal viruses China's government needs to take important measures to prohibit the sale of wild animals in the market At present, Beijing has begun to implement this policy, but it took measures only after the epidemic was out of control last month Francois, a researcher from the French National Science Center Renaud said that every time we try to put out the fire, once it is put out, we will wait for the next time to continue to put out the fire; he suggested that we should make a monitoring list to describe in detail all animals that may spread the virus to humans, so that we can observe and study these animals before the advent of epidemiology in the future, so that we can take the initiative and effectively contain the epidemic situation Momentum Reference: pangolin suspect ා 1 as direct source of coronavirus outbreak
