At least four Americans were infected with a version of Covid virus, seen majorly in mink in 2020, likely becoming the first spillover cases in the country, the US Centers for Disease Control and Prevention (CDC) has said.

The infected people are from Michigan — two employees of a Michigan mink farm that experienced a coronavirus outbreak in October 2020 — while the other two had no known links to the farm.

This suggests that the mink variant may have been circulating more widely among area residents at the time, the New York Times reported.

The cluster, which previously included just three cases, represents the first known instance of possible animal-to-human transmission of the virus in the US.
