The study confirmed for the first time that wild animals are widely exposed to the new crown virus, and one third of the white-tailed deer in the northeastern United States may be infected with the new crown

Recently, a report on the website of "Nature" reported that US Department of Agriculture researchers conducted a coronavirus antibody analysis study on the serum samples of some white-tailed deer in the northeastern United States and found that one third of the white-tailed deer sampled had coronavirus in their bodies.

The results of this study were published in a preprint on bioRxiv on July 29, and the article has not yet been peer reviewed

The biggest finding of the study: one-third of white-tailed deer in the northeastern United States have antibodies against SARS-CoV-2-which suggests that they have been infected with the virus

Based on the total of samples in 2020 and 2021, the proportion of coronavirus-related antibodies detected in serum samples of white-tailed deer in the northeastern United States is one-third

The article also suggests that SARS-CoV-2 monitor the probability of food chain participants such as susceptible predators interacting with deer

The researchers said that the rapid exposure of large numbers of animals to the virus is worrying, but more research is needed to assess whether deer can infect each other and other species in the wild
.

"This is an interesting observation, but it still needs to be interpreted with caution," said Aaron Owen, an infectious disease researcher at Zhejiang University in China

According to Linda Saif, a virologist at Ohio State University in Worcester, the key question is "how does the virus spread to deer, and whether it will spread from infected deer to other wild animals or domestic animals (such as cattle)
.

"

According to reports, previous experiments have shown that white-tailed deer can be infected with the coronavirus, and the virus can spread in the herd
.
A U.
S.
Department of Agriculture spokesperson said that from the test results of the samples and the fact that there are a large number of white-tailed deer in the United States and their contact with people, white-tailed deer in other states may also be infected with the coronavirus
.

Banerjee, a virologist at the University of Saskatchewan in Canada, said that research data showed that white-tailed deer were infected with the coronavirus at a certain point in time, but the researchers did not test the viral RNA of these animals, so it is not yet clear whether they are.

.

The report said that a big question now is how these white-tailed deer were infected
.
Banerjee said that if these white-tailed deer all have the same source of infection, other animals may also come into contact with this source of infection
.

In summary, the results of the study emphasize the importance of SARS-CoV-2 investigations on deer, their predators, and other animals in close contact with deer
