Protective Immunity and Persistent Lung Sequelae in Domestic Cats after SARS-CoV-2 Infection

Severe acute respiratory syndrome coronavirus 2 readily transmits between domestic cats. We found that domestic cats that recover from an initial infection might be protected from reinfection. However, we found long-term persistence of inflammation and other lung lesions after infection, despite a lack of clinical symptoms and limited viral replication in the lungs.

Automated summary

It is easily for Severe acute respiratory syndrome coronavirus 2 to transmit between domestic cats. Recovered domestic cats may have some protection against reinfection, but long-term persistence of inflammation and other lung lesions were found after infection despite limited viral replication and absence of clinical symptoms.
