Abstract

S ARS-CoV-2 has been detected in farmed and feral American mink (Neovison vison) in multiple countries, and extensive environmental contamination and human-to-mink and mink-to-human transmission has been documented (1-5). These factors have led to strict measures in mink farms and mink-farming countries to prevent the spread of the disease. In late 2021, a new SARS-CoV-2 variant (Omicron), characterized by possibly milder symptoms and more efficient human-tohuman transmission, was detected, but its infectivity and spread in American mink is unknown (6,7).
