| Epidemiological comments |
22 Apr 2020 Update--Two cats from separate households were sampled for respiratory illness. Clinical signs included sneezing and ocular discharge. Samples from the cats were tested by SARS-CoV-2 PCR after testing negative for other respiratory pathogens. One cat is from a two-cat household with a known COVID-19 affected person, the other from a household in an affected neighborhood and allowed to go outdoors. SARS-CoV-2 was confirmed in samples based upon molecular testing (PCR and sequencing) of samples from the initial testing laboratory and follow up samples obtained directly. Both cats are expected to fully recover, and testing of follow up samples indicated both cats were clearing the infection. |
