Some animals that live with humans can carry viruses.
The severe acute respiratory syndrome caused by SARS-CoV-2 coronavirus (COVID-19), which began in Wuhan, China, can also be transmitted to animals.
Despite tremendous efforts to combat the disease, COVID-19 has now spread to over 100 countries and has triggered a global pandemic. SARS-CoV-2 is thought to have originated in bats; however, intermediate sources of the virus in animals are completely unknown. Biologists led by Hualan Chen of the Harbin Veterinary Research Institute of the Chinese Academy of Agricultural Sciences have studied the susceptibility of ferrets and domestic animals to SARS-CoV-2. They found that SARS-CoV-2 does not replicate well in dogs, pigs, chickens, and ducks, but is effective in ferrets and cats. The virus can be transmitted to cats through drops that fly out when breathing.
Moreover, the virus spread easily among ferrets, but did not affect their health. In cats, the situation was worse, especially with kittens. Almost all of them died in case of infection with coronavirus. The study provides important information on animals carrying SARS-CoV-2 and animal management to control COVID-19.
