40% of the wild deer in the United States are infected with the novel coronavirus, and the mutation “returns” to humans. The most worried

Contact WeChat: QQ657522676 is not just human infection with COVID-19, COVID-19 has spread to wild animal, the United States has a large number of deer infected with COVID-19! Source: Sydney today just recently, the number of people diagnosed with novel coronaviruss in the world has exceeded 200 million! Many of the world is still in the “severe epidemic situation”, and the Delta mutation virus is constantly raging and spreading

.

Under such a severe situation, a worrying scene has happened

.

Not only is human infection with COVID-19, COVID-19 has spread to wild animals, but there are a lot of animal infecting COVID-19 in the United States

.

40% of the deer blood sample has COVID-19 antibody

.

In addition, Indonesia recently reported for the first time that rare animals were infected with a novel coronavirus: two Sumatran tigers “caught”  。 It is hard to imagine that under the epidemic situation, there has been a large-scale infection of wild animals and the infection of many other animals

.

As for their infection route and impact on human beings, further investigation and research are still needed

.

However, mankind is afraid to face even more formidable difficulties and challenges

.

01, the wild deer in the United States were found to be infected with the novel coronavirus virus locally

.

In August 2nd, the top scientific journal Nature published an article entitled “diffusion of novel coronavirus virus in the United States” on its official website

.

It pointed out that 40% of the deer blood samples had a novel coronavirus virus antibody

.

According to the introduction of nature, this wild animal found to be infected with COVID-19 is a common white deer in the North American continent

.

The study shows that over 1/3 of the white tailed deer in the northeastern United States have antibodies against SARS-CoV-2, which means that these deer have been infected by COVID-19

.

In addition, the researchers also tested the archived blood samples of white tailed deer since 2011 and found that there were sars-cov-2 antibodies in three samples in early 2020, when sars-cov-2 had just begun to spread in the United States

.

Given the percentage of SARS-CoV-2 antibodies detected in the study and the widespread distribution of white tailed deer in the United States and close contact with humans, the US Department of Agriculture said that the white tail deer in other states of the United States probably also had infected COVID-19

.

Researchers are also worried about whether there may be new animal populations that carry COVID-19

.

Once it appears, COVID-19 can get there, which may threaten the efficacy of vaccines and may re spread to humans after the novel coronavirus pandemic has subsided

.

Will it be repeated like Ebola? In order to assess the risk, the researchers collected 385 blood samples of white tailed deer in four states of the United States (northeast Michigan, Pennsylvania, Illinois and New York) from January to March this year

.

By testing these blood samples, researchers found that 40% of the deer’s blood samples carried COVID-19 antibodies

.

And the deer investigated showed no signs of disease

.

For these deer infected with COVID-19’s path, the researchers pointed out: it is still a mystery

.

According to the introduction of Nature magazine, these deer may be infected by people, because there are a large number of white tailed deer in the United States, and they also have more contact with humans, but these deer may also be infected by polluted wastewater or other wild animals

.

Moreover, the source of infection of these deer may also lead to infection of other animals

.

Because this is the first time that extensive exposure to the virus has been observed in wildlife populations

.

So researchers need to do more research on this

.

For example, it is necessary to investigate and detect white tailed deer and local predators and other animals closely related to white tailed deer to assess whether COVID-19 will spread in wild animal populations

.

Animal transmission between species..

02 Indonesia first reported: two rare animals also infected with the novel coronavirus

.

In addition to the above deer group infection, in August 1st, the government of Jakarta, Indonesia, said in a statement: two Sumatran tiger in Jakarta’s South Korean zoo had been infected with COVID-19 in mid July of this year, and is recovering

.

The statement said that among the two tigers, TINO, a 9-year-old, suffered from shortness of breath, sneezing, runny nose and loss of appetite on July 9; Two days later, his companion, 12-year-old Harry, developed the same symptoms

.

Health workers tested COVID-19 in July 14th and showed positive results

.

Subsequently, the two tigers were immediately treated with antibiotics, anti-inflammatory drugs and vitamins

.

After 10 to 12 days, their condition improved and were under “close observation”

.

They are in good condition, their appetite has recovered and they are active again

.

The relevant zoo said that they were still investigating their infection routes

.

So far, all the keepers and staff on duty at the time of their onset had not been infected with Xinguan, and the zoo was not open to the public according to the epidemic prevention requirements of Jakarta at that time

.

According to the report, this is the first known case of novel coronavirus infection in animals in Indonesia

.

The Sumatran tiger is the most endangered tiger subspecies, and the only tiger subspecies in Indonesia

.

Only about 600 of them are expected to survive this

.

Under the outbreak, more and more animal infected with the novel coronavirus virus, animal species such as mink, dog, cat, lion and tiger, all have been tested positive

.

This phenomenon is no doubt worrying

.

In July 22nd, an unvaccinated rare snow leopard in the US San Diego zoo was detected positive for the novel coronavirus virus

.

This is not the first case of snow leopard in the United States

.

Last December, 3 snow leopards in the Luis Weil zoo were confirmed to have infected COVID-19

.

Last year, the first animal (a pet cat) was diagnosed with COVID-19 in Britain

.

Including in November last year, Denmark also had a “marten hard”, because COVID-19, around 17 million nationwide farming mink was killed, then Denmark has found 5 different kinds of mink mutant COVID-19

.

What is even more frightening is that COVID-19 has mutated and transmitted back to humans in mariculture

.

In November 2020, who announced that 214 people in Denmark had been infected with COVID-19 related to mink farms, of which 12 were infected with a “unique” variant of COVID-19

.

Although the sources and routes of infection of the deer are unknown, they only pray for a tragedy similar to that of “mink”

.

03, mankind will face more difficulties and challenges

.

US media reports say there is no reason to believe that the COVID-19 in the deer will follow the same trajectory as the wild marten

.

In any case, the uncontrollable host and the further evolution of the virus may mean that it is important to understand how COVID-19 invaded the deer and whether it spread among deer

.

Some researchers pointed out that the worrying thing is that if COVID-19 can infect wild animal such as deer in such a large area, it may also infect other wild animals and even animal

.

This may also mean that even if humans can control COVID-19 temporarily, the virus can find refuge in animal species, and quietly evolve, and then come back

.

So the most important thing is to find out how these spread happen to determine whether COVID-19 in the deer and other animal bodies pose a threat to humans

.

For animal infected with COVID-19, if they can not be effectively treated, there are only two consequences for large probability: “kill the virus” or “die”.
