A trio of new studies suggest COVID-19 is being passed between animals and humans:
- In one small Canadian study—which is yet to be published—antibodies found in the blood of pet cats and dogs suggest that a large proportion caught the virus from their owners.
- A second study tested 50 cats from households infected with the virus, and found that 6 of those cats tested positive for SARS-CoV-2 RNA.
- The third, a preprint study of infections across 16 Dutch mink farms, suggests outbreaks were triggered by humans but have since continued to circulate between the 2 species.
