I agree caution is needed and this report from the WHO is interesting to read.
Initial observations suggest that the clinical presentation, severity and transmission among those infected are similar to that of other circulating SARS-CoV-2 viruses. However, this variant, referred to as the “cluster 5” variant, had a combination of mutations, or changes that have not been previously observed. The implications of the identified changes in this variant are not yet well understood. Preliminary findings indicate that this particular mink-associated variant identified in both minks and the 12 human cases has moderately decreased sensitivity to neutralizing antibodies. Further scientific and laboratory-based studies are required to verify preliminary findings reported and to understand any potential implications of this finding in terms of diagnostics, therapeutics and vaccines in development. In the meantime, actions are being taken by Danish authorities to limit the further spread of this variant of the virus among mink and human populations.
Later on it states that they do not advocate travel ban to and from Denmark. It also seems that this mink strain has also been found in mink farms in Holland and the states and one of the Baltic countries. A non-human farmed animal or wildlife reserve for the virus is indeed worrying.
