The University of Tokyo, the University of Wisconsin, the National Center for Global Health and Medicine, and the National Institute of Infectious Diseases have jointly analyzed the ability of the virus to propagate and spread in cats isolated from patients with new coronavirus infection (COVID-19). ..As a result, it was clarified that the new coronavirus is frequently increased in the respiratory organs of cats and that it is easily transmitted among cats by contact transmission.
In the United States, two new coronaviruses have been detected in two domestic cats in New York City, and cats such as tigers and lions have also been reported to be infected at a zoo in New York City.
In this study, the new coronavirus was inoculated into the nasal cavity of cats.After that, it was investigated whether the virus was transmitted to the cohabiting cat by contact with the infected cat.As a result, the virus was transmitted in 3 out of 3 pairs.It was also found that the virus was more common in the respiratory tract of cats, and that cats infected with the virus showed no obvious symptoms.
The research team emphasizes that cats need to be kept indoors to protect them from infection.So far, no cases of the new coronavirus infecting humans from cats have been reported, but the Ministry of Health, Labor and Welfare stated on its website, "To prevent zoonotic diseases, refrain from excessive contact with animals and refrain from excessive contact with animals. After contacting animals on a regular basis, wash their hands and disinfect them with alcohol for fingers. "The Japan Veterinary Medical Association has also issued an opinion on the new coronavirus infection of pet animals.
