Epidemiological comments The dog was placed under quarantine on 26 February 2020 after its owner was hospitalised due to COVID-19 infection. Following veterinary examination nasal, oral, rectal swabs as well as faeces were taken after the dog’s admission to the quarantine facility. Nasal and oral samples tested positive for SARS-CoV-2. The dog has not exhibited any specific clinical signs. Additional samples taken on 28 February also tested positive. Investigations are continuing to determine the duration of virus detection.  Risk management measures are in place for this case, including cleansing and disinfection of the premises, and proper personal hygiene and protection. Mammalian pets from households with confirmed human cases of COVID-19 will be be placed under quarantine and veterinary surveillance for 14 days.
