First reported SARS-CoV-2 infections in companion animals in the United States

A case report from New York documented the first two confirmed SARS-CoV-2 infections in companion animals in the United States. The report involved two domestic cats. The specific exposure, intervention, comparator, and clinical outcomes were not reported. The main finding was that both animals tested positive for SARS-CoV-2. No data on viral load, symptoms, disease severity, or transmission dynamics were provided. Safety and tolerability information, including any adverse events or clinical signs in the animals, were not reported. The study has significant limitations. As a case report with a sample size of 2, it cannot establish prevalence, risk factors, or zoonotic potential. Key methodological details, including testing protocols and follow-up duration, are absent. The funding sources and potential conflicts of interest were not disclosed. For clinicians, this report serves as an initial signal that companion animals can be infected with SARS-CoV-2. However, it does not provide evidence for human-to-animal or animal-to-human transmission risk in household settings. Current infection control guidance for pet owners should be followed, but no new clinical actions are indicated by this isolated report.
