The workers passed the virus to weasels on farms in Denmark and now the weasels are spreading back to humans. According to scientists at the Statens Serum Institute in Denmark, 12 people who were infected showed a weaker ability to produce antibodies, meaning vaccine efforts could be complicated by contagion.
“As a government, we will do everything we can to ensure that the mutation is prevented and not spread further,” Frederiksen said. “That is why – unfortunately –; it is necessary to destroy all the weasels in Denmark.”
To do that, the country is also taking further tightening measures on areas with mink farms.
Denmark has more than 1,000 mink farms producing about 40% of the world’s mink pellets, most of which are exported to China and Hong Kong. Denmark plans to compensate mink farmers, but the government says the industry may be difficult to survive.
Coronavirus infections have launched a plan in the Netherlands to eliminate the industry, with hundreds of thousands of animals dying after an outbreak there. Spain has also banished tens of thousands of weasels.
There have also been reports of mink infection on farms in the United States, where thousands of older animals have been resistant to the virus.
