On Jun. 4, 2022, researchers reported that in areas with large cattle populations and a high prevalence of SARS-CoV-2 infection in humans, close contact between livestock and farmworkers may cause reverse zoonotic infections in cattle, as was described for highly sensitive animal species, such as minks, cats, and dogs.

The role of cattle in SARS-CoV-2 transmission remains unclear. Although cattle are potentially sensitive to SARS-CoV-2, this study aimed to determine the susceptibility of cows to active SARS-CoV-2 infection at a farm where there was a COVID-19 outbreak among the farmworkers. SARS-CoV-2 and BCoV are both betacoronaviruses, and BCoV is very similar to human coronavirus (HCoV) OC43 (Betacoronavirus 1) [22]. Thus, after the samples tested positive for SARS-CoV-2, they were also analysed for BCoV.
