It turns out that there is a high possibility that China's new coronavirus has transmitted `` from snake to human ''

A new coronavirus (2019-nCoV) discovered in Wuhan, China in December 2019 caused 17 deaths and more than 540 patients as of January 22, 2020, affecting Japan and the United States. Infected cases have been confirmed in five countries including the world. It has been found that the source of such new coronavirus infection is likely to be snakes.

The new coronavirus, first discovered in Wuhan City, Hubei Province, China, was originally supposed to be `` infected from human to human, '' and cases have been found in Japan, the United States, South Korea, Thailand, etc. You. In response to the spread of the damage, the U.S. Centers for Disease Control and Prevention (CDC) has raised the `` Vigilance Alert Level '' to `` 2 '' to alert travelers to public health, and called for stronger precautionary measures. .

Identification of the source of infection is important in establishing treatments and preventive measures for new coronavirus infections. Wei Ji and his colleagues at Peking University Health Science Center analyzed the genes of the new coronavirus and compared the gene sequences of more than 200 existing coronaviruses.

As a result, the new coronavirus was found to be close to the two SARS coronaviruses found in bats in China. From this, the research group initially thought that the new coronavirus was derived from bats.

However, the research group analyzed the virus in more detail. When the virus infects cells of living creatures including humans, it needs to recognize the receptor on the cell surface, so the research group analyzed the gene sequence that generates a protein that recognizes the novel coronavirus receptor Did.

Analysis revealed that the new coronavirus had transmitted another host before it had transmitted humans from bats. The research group concluded that the creatures that infected humans with the new coronavirus were snakes. However, the mechanism by which the snake virus, a thermophilic animal, adapted to humans, a thermophilic animal, remains unclear.

The research group pointed out that `` to respond to a new virus, it is necessary to identify and develop an effective vaccine, but you should first test from approved antiviral drugs, '' treating the new coronavirus He said that establishing a law was urgently needed.
