Studies show that cats and dogs respond differently to the new coronavirus
the new coronavirus infection (COVID-19), which has killed more than one million people worldwide, on' dogs and cats. ' Infection with the new coronavirus (SARS-CoV-2) does not cause any noticeable symptoms. ' However, it has also become clear that dogs and cats differ significantly in various respects, such as the immune response to the virus.
A research team at the Faculty of Veterinary Medicine, Colorado State University said, 'Pet dogs and cats are about the effects of

An experiment conducted by a research team at Colorado State University was to 'administer SARS-CoV-2 to dogs and cats.' The research team diluted the nasal cavity of 3 dogs and 7 cats without antibodies to feline coronavirus , which is a different type of coronavirus from SARS-CoV-2, with phosphate-buffered physiological saline. SARS-CoV-2 was administered.
After the experiment, neither dogs nor cats showed clinical signs such as sneezing, coughing, diarrhea, and loss of appetite, but upon closer examination, cats had moderate ulcerative rhinitis, mild tracheitis, and minimal levels of lung. It was confirmed that he had developed alveolar edema. In addition, when the research team investigated 'the amount of virus released from the nose and mouth', cats continued to release SARS-CoV-2 for up to 5 days, while dogs released SARS-CoV-2. It was confirmed that it did not.
In addition, the research team is also conducting an experiment to 'administer SARS-CoV-2 again to cats once infected with SARS-CoV-2.' As a result of this experiment, it was confirmed that an effective immune response occurs in the body of a cat once infected with SARS-CoV-2 and that it does not re-infect SARS-CoV-2.
From a series of results, the research team said, 'Cats are susceptible to SARS-CoV-2 and shed the virus from the mouth and nose for a long time without any signs of onset.' 'Cats are re-infected with SARS-CoV-2.' Not doing so may help in the development of the COVID-19 vaccine. '
Regarding the question, 'Should people who have dogs and cats take measures against COVID-19?', The research team said, 'Cats and dogs play an important role in infecting humans with COVID-19. There is almost no evidence that it is. '
