The new coronavirus has infected more than 1.13 million people worldwide, and the United States ranks first with 330,000 diagnoses. The tragedy is that various animals have also begun to suffer.
Previously, dogs and cats have been confirmed to be infected. The American Zoo has now confirmed that it has always been a tiger in Malaysia.
According to media reports, although the Bronx Zoo, the largest zoo in New York, has been closed after March 16, a 4-year-old female Malaysian tiger in the park was tested positive for the new coronavirus after a dry cough.
What's more troublesome is that she may not be the only animal infected. Her sister-another female Malaysian tiger, two Siberian tigers, and three African lions are also suffering from dry cough and loss of appetite. An asymptomatic employee is contagious, and the final result will have to be announced by the USDA's veterinary laboratory.
Recently, a paper published by Shi Zhengli of Wuhan Virus Institute, Jin Meilin and Zhong Zou of Huazhong Agricultural University showed that the study collected a group of serum samples from cats in Wuhan, including 102 after COVID-19 outbreak and 39 before outbreak. Copies.
Through indirect enzyme-linked immunosorbent assay (ELISA) on the receptor binding domain (RBD) of SARS-CoV-2, it was found that 15 (102.7%) of 102 cat sera collected after the outbreak were positive.
The study pointed out that the new coronavirus has poor replication ability in dogs, pigs, chickens and ducks, but it can effectively replicate in ferrets and cats. The new coronavirus can be transmitted between cats through respiratory droplets.
From pet cats to tigers and lions, this means that felines have become humans that are easily infected by the new coronavirus.
