Lions and tigers had already contracted the virus, but have recovered.
If this pandemic has taught us anything it’s that we cannot escape the world we have shaped.
Mink are the only animal known to both catch the virus from people and transmit it to them.
Mink in Denmark are not the only animals that could become reservoirs for the coronavirus to spread new mutations to people.
