Mongolia’s National Zoonotic Disease Research Center said on the 11th that Mongolia has reported the first case of animal infection with COVID-19, and at least 7 beavers have detected a mutated COVID-19 virus Delta strain. The infected beavers have symptoms such as coughing and runny nose, and all these beavers have recovered.
A news report published on the website of the British "Nature" magazine said that US Department of Agriculture researchers conducted a COVID-19 virus antibody analysis study on serum samples of some white-tailed deer in the northeastern United States and found that one third of the white-tailed deer were sampled. There are antibodies related to the COVID-19 virus, which indicates that they have been infected with the COVID-19 virus.
According to reports, researchers tested 385 white-tailed deer blood samples collected in Michigan, Pennsylvania, Illinois, and New York from January to March 2021, and found that 40% of the samples could detect COVID-19 virus-related antibodies , But the deer under investigation showed no signs of illness.
After testing some samples that were saved earlier, the researchers found that in the samples collected in early 2020, three samples detected related antibodies; among the samples collected in 2019, related antibodies were detected in one sample. Based on the total of the samples in 2020 and 2021, the proportion of COVID-19 virus-related antibodies detected in serum samples of white-tailed deer in the northeastern United States is one-third.
In November 2020, the French Ministry of Agriculture issued a press release stating that the French National Health and Security Agency started a scientific research project in the middle of the month to detect the presence of the COVID-19 virus in 4 mink farms. It has been in a farm in Eure-Loire. Discovered the spread of the COVID-19 virus. The French Ministry of Agriculture and other departments immediately instructed the farm to immediately culminate about 1,000 mink farmed here and destroy related products to protect public health.
Coincidentally, the Danish government announced in November 2020 that in view of the fact that there have been many cases of mink transmitting the mutated COVID-19 virus to people in the country, the government has decided to culminate all domestic mink farms, and deal with 7 cities with more mink farms. Implement stricter anti-epidemic and restrictive measures.
Danish Minister of Health Magnus Hojnik said at a press conference at the time that the health department had been aware of the transmission of the COVID-19 virus from mink to people for some time. The National Serum Institute found that Denmark’s first case of “mink transmission” The case can be traced back to August 2020.
The U.S. Department of Agriculture also announced in December 2020 that a wild mink in Utah was infected with the COVID-19 virus, marking the first case of a wild animal infection in the United States. U.S. Department of Agriculture staff discovered this case when they were screening wild animals near a mink farm that was infected with the COVID-19 virus in Utah.
The World Health Organization stated at the end of last year that six countries including Denmark, the United States, Italy, the Netherlands, Spain and Sweden have reported the COVID-19 virus in mink farms. The WHO said at the time that the COVID-19 virus was transmitted from humans to minks, and then spread between minks, and there was a risk of transmission to humans again. Denmark has found multiple cases of mink transmitting the mutated COVID-19 virus to humans. Medical experts and health officials around the world are studying the possible threats to humans caused by the COVID-19 virus in animals.
In addition, from March to April 2020, the Bronx Zoo in New York City confirmed that 5 tigers and 3 African lions were infected with the COVID-19 virus. In January of this year, several gorillas at the San Diego Wildlife Park in California tested positive for the COVID-19 virus. This is the first time that a primate other than humans has been infected with the COVID-19 virus. In addition, many countries and regions have reported pet cats and dogs infected with the COVID-19 virus since last year.
