According to a BBC report from the British Broadcasting Corporation on Nov.5, up to 17 million minks will be euthanized in Denmark because a new mutated coronavirus that can be transmitted to humans was previously discovered in mink farms.
The virus mutation has infected 12 people
According to a Reuters report on the 4th, Denmark has detected the presence of a new coronavirus in mink and has mutated on 5 farms across the country, and the number of people infected with this mutated virus has reached 12. The Minister of Danish health Hiyuk said on day 4 that although these patients are not seriously ill, the antibodies in their bodies do not respond positively to the mutated virus. “Research shows that these mutated viruses can affect the current vaccine. They pose a threat to vaccine development.”
Danish Prime Minister Mette Frederiksen called the current situation “very, very serious”. He cited a government report that the mutant virus will weaken the body’s ability to form antibodies, which may invalidate the new coronavirus vaccine that is currently being developed. She said at the press conference: “We have a great responsibility to the population of our country, but with the virus mutation now discovered, we also have a greater responsibility to the rest of the world. Therefore, we must take decisive action.” It is necessary to hunt all minks. “
The mink farming industry will be hit hard
Denmark is the largest mink producer in the world. This time, Denmark plans to grow 17 million minks on more than 1,000 farms. Therefore, the compensation paid by the government to mink producers can reach 5 billion DKK (about 790 million). American dollars).
According to Bloomberg News, Denmark has culled thousands of minks in recent months due to the outbreak. According to a briefing on Wednesday, 217 of the 1,139 Danish mink farms have discovered the new corona virus.
The Danish government stated that the local food and veterinary administration is slaughtering the infected mink, and on farms where the new corona virus is not detected within 8 kilometers of infected animals, farmers should also implement their own slaughter. .
The number of minks that have been euthanized is not yet known. The government stated that farmers raising minks that are not infected will receive corresponding compensation, while those infected with the virus will receive a small compensation. The Danish government stated that the purpose of this measure is to encourage farmers to strengthen their own epidemic prevention and control.
The BBC noted that Denmark will kill 17 million minks on more than 1,000 breeding farms. Local police chief Vogeld believes it will be a “big job.” The president of the Danish Association of Mink Breeders believes that the government’s decision is a disaster for the industry and Denmark.
“Who infects whom”, humans and animals?
What is particularly concerning is that the new coronavirus has been detected in minks in many parts of the world, but this is the first time the virus has been found to mutate.
According to public reports, as early as April this year, two mink farms in the Netherlands detected the new corona virus in mink. At the time, experts believed that the mink might have been infected by farm personnel. In June, Denmark discovered the new coronavirus in mink for the first time on a farm. In July, it was detected that 90% of minks on a farm in Spain were infected with the virus. To be cautious, nearly 1.8 million minks were killed in three countries. In August, five minks were found to have the new coronavirus on two large mink farms in the United States, the first time in the United States. Investigations at that time showed that all employees on these farms were infected with the virus. However, the researchers did not have clear evidence to show whether humans were infected with the mink virus or whether there is two-way transmission. According to the WHO, the transmission of the virus in mink farms can be bidirectional, but this type of transmission of the virus is “rare”. As for how the new coronavirus spreads between humans and minks, or two-way transmission, the academic community has not concluded.
Shortly after the new coronavirus spread globally earlier this year, there have been reports of animal infections. Early research reports believed that Chinese pangolins and chrysanthemum bats are the hosts of the new coronavirus, and the virus can be transmitted to humans from them. Then there was news that minks, domestic cats in Hong Kong, and tigers in American zoos were infected. According to foreign studies, there are about ten species of animals that are known to be susceptible to the new corona virus. In the laboratory setting, common hamsters, rabbits, and marmosets are susceptible to the new corona virus, while pigs, ducks, and chickens are not susceptible to infection. Research on common livestock such as sheep and horses in this area.
Jiang Qing, an epidemiologist and former dean of the Fudan University School of Public Health, told the Global Times reporter on the 5th that the coronavirus is a very large family and that only a small part of the virus can cause disease. Therefore, it is necessary to sequence the genes of the new coronavirus carried by the mink to determine the distance between it and the new coronavirus infected by the human body, and the strength of the correlation. Jiang Qingwu believes that viruses are mutating all the time, and Denmark needs genetic sequencing to make objective judgments. “If the relationship between the two is distant, you don’t need to be too nervous, you just have to watch closely. Otherwise, the Danish government really needs to take the appropriate prevention and control measures.”
