Epidemiological comments

2 Jun 2020 Update�A pet German Shepherd dog from a household with known COVID-19 affected inhabitants was sampled for respiratory illness. Clinical signs included severe lethargy, diagnosed as hemolytic anemia. The dog tested positive for SARS-CoV-2 at a private veterinary laboratory. SARS-CoV-2 was confirmed in this dog based upon molecular testing (PCR and sequencing) of samples both from the initial testing laboratory and follow up samples obtained directly. Virus neutralizing antibody was detected in follow-up samples from the affected dog as well as a second pet German Shepherd dog in the household who showed no clinical signs of disease and tested negative by PCR. The first dog is progressively recovering.
