Ferrets, Humans and Cats Among Most Susceptible to Covid

Researchers conducting an analysis of ten different species found that humans — followed by ferrets and, to a lesser extent cats, civets and dogs — are the most susceptible animals to SARS-CoV-2 infection. (The study also found that ducks, rats, mice, pigs and chickens had lower or no susceptibility to infection compared to humans.)

The scientists argue that understanding SARS-CoV-2 infectivity across different species can better inform public health measures, helping reduce human contact with other susceptible animals and avoiding the potential prolongment of the COVID-19 pandemic.
