Epidemiological comments |
10 Jun 2020 Update—A domestic cat from a known positive COVID-19 household was sampled for respiratory illness. Clinical signs included fever, oral lesions and ulcerations on the tongue. The cat tested negative by feline respiratory panel, FIV and FeLV, and positive by feline coronavirus serologic test, a common finding. The initial testing laboratory also conducted a SARS-CoV-2 test. Infection with SARS-CoV-2 was confirmed at NVSL based upon molecular testing (PCR and sequencing). The cat is reportedly recovering. |
