Ferret owenrs in Wales are being urged to regsiter their animals Owners of ferrets and other related animals such as minks and weasels in Wales are being given advice on how to keep themselves and their animals safe from possible Covid infections. In autumn 2020, events in Denmark confirmed it is possible for mink to infect humans with Sars-CoV-2, the virus which causes Covid-19. While mink farming is banned in the UK, other mammals in the mustelinae family, such as ferrets, are now known to be highly susceptible to Sars-CoV-2. Research has demonstrated new variants can arise in ferrets and other mustelinae, and they can spread infection within their own species.
