According to the American "Nature" science magazine, a common wild animal in the North American continent has recently been found to be infected with a large area of the new crown virus, but the reason why these animals are infected with this virus is still a mystery!
Judging from the introduction of Nature magazine, this wild animal that was found to be infected with the new crown virus in a large area is a common white-tailed deer in the North American continent.
According to the journal, a survey conducted by canadian and American scholars found that 40 percent of the 385 white-tailed deer blood samples collected in four states of Michigan, Pennsylvania, Illinois and New York in the United States from January to March this year were detected with antibodies to the new crown virus, which means that the deer have been infected with the new crown virus.
At present, the academic papers involved in this matter have been pre-published on the academic preprint platform bioRxiv and have not yet been peer reviewed. However, this matter has attracted the attention of many scientific journals, including the journal Nature.
Some researchers pointed out that the worrying part of this matter is that if the new crown virus can infect such a large area of wild animals as deer, it may also infect other wild animals, even domestic animals. And this may mean that even if humans can control the new crown virus for a while, the virus can find a "refuge" in wild animals, quietly evolve, and then make a comeback.
At the same time, researchers are equally confused about another question: how exactly the deer contracted covid-19.
Judging from the introduction of the journal Nature, these deer may be infected by humans, because the white-tailed deer in the United States are large in number and have more contact with humans.
But the deer may also be infected by contaminated wastewater or by other wildlife. Moreover, the source of infection in these deer is likely to cause infection in other animals.
Then, in view of the WHO who has said that the new crown virus is more likely to come from the natural world, and at the same time said that the possibility of laboratories cannot be ruled out, Geng Zhige believes that this latest situation in the United States once again shows that WHO needs to go to the United States for traceability research: on the one hand, it is clear that more than 25 million netizens in China have signed up for investigation of Fort Detrick, on the other hand, it is also necessary to investigate the white-tailed deer infection in the United States.
