The United States for the first time reported that pet cats infected with the new coronavirus, the new crown pneumonia can infect the animal species?

The U.S. Centers for Disease Control and Prevention and the Department of Agriculture jointly announced Tuesday that two domestic pet cats in New York State have been confirmed to be infected with the new coronavirus, the first domestic pet infection in the United States.
what animal species can be infected with new crown pneumonia? Discussions on the issue have not stopped since the outbreak of the New Crown outbreak.
Now, several groups of Chinese scientists have published two direct evidences on the pre-printed platform bioRxiv that cats and ferrets are susceptible to the new coronavirus, while dogs and other animals are less susceptible.

U.S. first reported pet cat infection with the new crown virus Washington, April 22 (Reporter Tan Jingjing) The U.S. Centers for Disease Control and Prevention and the Department of Agriculture jointly announced on the 22nd, located in New York State, the United States two domestic pet cats confirmed to be infected with the new coronavirus, this is the first time the United States found domestic pet infection.
, four more tigers and three African lions have been confirmed to be infected at the Bronx Zoo in New York City.
the two pet cats, from different parts of New York State, were sent for testing after developing respiratory symptoms and are expected to make a full recovery.
one of the cats' families has so far been undiagnosed, the cat's route may come from asymptomatic infections or people with mild symptoms at home, or from people exposed to contact outside the home;
the U.S. Centers for Disease Control and Prevention and the Department of Agriculture said there was no evidence that pets played a role in the spread of the virus, and further research was needed on the possible effects of different animals on the outbreak.
According to the Bronx Zoo in New York, 22, the end of March in the park, a 4-year-old Malayan tiger appeared dry cough and loss of appetite and other symptoms, after testing confirmed the infection of the new crown virus.
staff then tested positive for the new crown virus on some of the park's other large cats, which resulted in four tigers and three African lions testing positive.
these infected lions and tigers have now been relieved with coughing.
the park believes the animals were infected by an asymptomatic infected person working in the park.
the zoo was temporarily closed on March 16 due to the new crown outbreak.
National Institute of Allergy and Infectious Diseases Director Fu chi said at a White House press conference on the 22nd, although animals have been found to be infected with the new coronavirus through humans, but there is no evidence that the new coronavirus can be transmitted to humans through pets.
Extended Reading: What are the animal species that can be infected with new crown pneumonia? Discussions on the issue have not stopped since the outbreak of the New Crown outbreak.
who previously said there was no evidence that the virus could infect other pets or livestock.
Although, Hong Kong and Belgium have reported that two dogs and a cat have been infected with the new crown virus.
, however, overall, there has been a large lack of evidence of other livestock infections to date.
Now, several groups of Chinese scientists have published two direct evidences on the pre-printed platform bioRxiv that cats and ferrets are susceptible to the new coronavirus, while dogs and other animals are less susceptible.
animal infection experimental results show that cats are susceptible to infection and infection of the new coronavirus March 31, Harbin Veterinary Research Institute research team published a pre-release based on a variety of human tissues and multiple animal ACE2 receptors (the virus enters mammalian cells caused by the "gate") found that the presence of this ACE2 receptor in multiple tissues of the human body, consistent with some patients showed the distribution of symptoms outside the respiratory tract, indicating that the virus has the potential to infect other human tissues other than the respiratory tract;
then the team conducted some animal experiments.
experiment, inoculating the high-load new coronavirus into the noses of five domestic cats. After
euthanized two of the cats six days later, viral RNA and infectious virus particles were found in their upper respiratory tract, indicating that the cat was infected with the new coronavirus.
placed three other infected cats next to the uninfected cat cage.
researchers later detected viral RNA in one of the cats, suggesting that the cat could be infected through the respiratory tract.
, the study found that all four infected cats had specific antibodies detected, further indicating that cats were susceptible to the new coronavirus.
, however, the study also found that infected cats did not show symptoms of the disease - are asymptomatic infections.
team of five puppies in the same experiment, found that two dogs from the feces of the virus RNA, but did not detect the infectious virus.
experiments on ferrets found that ferrets are highly susceptible to the new coronavirus.
also found no evidence of infection in these animals in similar studies of pigs, chickens and ducks.
serum epidemiological investigation confirmed that cats can be infected with the new coronavirus on April 3, Wuhan Virus Research Institute Shi Zhengli and Huazhong Agricultural University Jin Meilin, etc. in bioRxiv published serum epidemiological investigation confirmed that cats can be infected with the new coronavirus.
researchers were tested for 102 cat blood samples during the COVID-19 outbreak, compared with 39 collected before the outbreak, and found that 15 of the 102 cat serums after the outbreak were positive (14.7%) positive;
explained that during the outbreak, a considerable proportion of cats in Wuhan were infected with the new crown virus, confirming the conclusion that cats at Harbin Veterinary Research Institute are susceptible to infection and infection of the new crown virus.
two studies have reached consistent conclusions that cats are susceptible to infection and infection of the new coronavirus.
other common, such as dogs, chickens and ducks, pigs and other poultry and livestock are not easy or can not be infected with the new coronavirus.
