Epidemiological comments 31 Dec 2020 Update-- Pennsylvania (PA): A domestic dog from a known positive COVID-19 household was confirmed positive for SARS-CoV-2 at the National Veterinary Services Laboratories based upon molecular testing (PCR and sequencing). The dog has a history of immune-mediated hemolytic anemia and showed clinical signs of lethargy and hemorrhagic diarrhea, which have reportedly resolved. Kentucky (KY): Two previously reported and PCR-positive snow leopards at a zoo were confirmed positive for SARS-CoV-2 at the National Veterinary Services Laboratories based upon molecular sequencing. All snow leopards are progressively recovering and remain off public exhibition since the onset of clinical signs. There are no other suspected cases of SARS-CoV-2 in any animals from the zoo at this time. Virus neutralizing antibodies in the absence of other positive test results have been detected in the following animals (listed by state): 1 dog (AZ) As of 31 Dec 2020, total number of animals with detections of virus neutralizing antibody in the absence of other positive test results:53
