Epidemiological comments 5 Aug 2020 Update—Louisiana (LA): 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 affected dog, who had a history of hip and back lameness, was in close and prolonged contact with the COVID-positive owner and was presented to the veterinarian after showing signs of hind end lameness. Due to severe deficits and inability to stand, the dog was euthanized with a probable diagnosis of progressive intervertebral disc disease. New York (NY): The dog from Richmond County, NY confirmed positive for SARS-CoV-2 has been euthanized with a probable diagnosis of lymphoma. South Carolina (SC): Two additional dogs in Charleston County, SC who shared the same household with the SARS-CoV-2 confirmed positive dog have tested negative for SARS-CoV-2 by PCR and virus neutralization (VN).
