Mink and the Coronavirus: What We Know

Final week, Denmark introduced its intention to cull all farmed mink, some 17 million, out of concern {that a} mutated model of the coronavirus may diminish the effectiveness of potential vaccines.

The choice has since been placed on maintain due to questions of authorized authority. Whereas the federal government seeks new laws, culls of mink at contaminated farms proceed, as does dismay in different international locations and a debate amongst scientists concerning the validity of the issues.

Six international locations — Denmark, the Netherlands, Spain, Sweden, Italy and the US — have reported instances of farmed mink contaminated with SARS-CoV-2, the virus that causes Covid-19. Mink catch the virus from people and go it on to one another. Not like canine, cats and another animals, which categorical solely gentle signs, if any, mink can sicken and die from an an infection.

Listed here are solutions to primary questions on mink and the coronavirus:

Sure. In Denmark, mink have contracted the virus and unfold it to individuals. The identical occurred within the Netherlands this 12 months.

Sure. In additional than 200 individuals, Danish authorities have documented a number of variants of the virus that comprise mutations originating in mink. The virus additionally mutates in individuals.

No. There isn’t any proof that any of the mutations that originated in mink make the coronavirus extra transmissible in people or make people sicker.

Danish well being authorities have been involved that one set of mutations in a variant of the virus referred to as cluster 5, which had contaminated a minimum of 12 individuals, might make a possible coronavirus vaccine much less efficient.

One of many mutations happens on part of the virus — the spike protein — that’s focused by many potential vaccines. In lab research, cells with this variant of the virus have been uncovered to antibodies, which didn’t act as strongly as that they had with different coronavirus variants.

However this was a really preliminary check. The response to antibodies in laboratory cells doesn’t essentially point out that the mutated virus can be immune to vaccines; it merely raises that risk.

The World Well being Group and unbiased specialists mentioned there was no proof to date that the cluster 5 variant would diminish the worth of vaccines at the moment in growth.

Scientists say that there are causes past this specific mutated virus for Denmark to behave. Mink farms have been proven to be reservoirs for the coronavirus, and mink are able to transmitting the virus to people. They’re the one animal recognized to take action.

This set of mutations is probably not dangerous to people, however the virus will probably proceed to mutate in mink because it does in individuals, and the crowded circumstances of mink farms might put evolutionary pressures on the virus completely different from these within the human inhabitants. The virus might additionally bounce from mink to different animals. These are all worrisome prospects, significantly within the midst of a resurgence of the virus within the human inhabitants.
