Mink infected with Omicron were consistently PCR-positive from day 3 onwards, indicating mink-to-mink transmission. Infectious virus was detected in cell culture even before it was detected by PCR.

Despite the reports of lower virulence of Omicron, mink experience clinical disease and nasal and pulmonary microscopic lesions that closely resemble infection with previously reported variants in mink and humans.
