According to WHO statistics, as of 0:00 BEIJING time on April 6, the cumulative number of confirmed cases of new coronary pneumonia in the world exceeded 1.13 million, and 208 countries and regions in the world have confirmed new coronary pneumonia. In the face of this raging outbreak of new coronary pneumonia, it is not only humans, but also the animal community that is under attack…
On the evening of 19 March, the Agriculture, Fisheries and Conservation Department of the Hong Kong Special Administrative Region Government informed that a dog had been found to have tested positive for the new coronal pneumonia virus.
On April 6, a 4-year-old tiger tested positive for the new corona virus at the Bronx Zoo in New York, the first animal in the U.S. to appear, Bloomberg reported.
Recently, a paper entitled “Virus Shi Zhengli and so on found that 14.7% of cats have been infected with the new coronavirus!” Prevention and control measures should be changed” article brushing the circle of friends, causing a wave of panic.
Recently, scientists from the Harbin Institute of Veterinary Medicine of the Chinese Academy of Agricultural Sciences and the National Center for Animal Disease Prevention and Control reported that cats are more susceptible to new coronaviruses than dogs, pigs, chickens and ducks.
So why are cats more susceptible to infection? Can a cat infect a person or other animal? During the outbreak, how can the officer protect themselves and the cat, what should be paid attention to in daily life?
Why are cats more susceptible to infection?
To answer this question, you need to start with the infection mechanism of the new coronavirus.
The new coronavirus is as similar as 96% to some of the coronavirus genes in bats. The original coronavirus in bats could not directly infect humans, it is the 4% mutation that makes the virus capable of infecting humans.
The reason to infect humans lies in the bulging rods on the surface of the new coronavirus.
The bar is called s-protein, similar to a key. The key opens a receptor in the body called ACE2. Only when bound to the “ACE2” receptor will the new coronavirus truly infect the host.
Where’s this ACE2? In the lungs, small intestine, duodenum have expression, so people infected with the new coronavirus will first appear the symptoms of the lungs, digestive tract.
The new coronavirus specifically finds ACE2 receptor binding, which means that the closer the ACE2 receptor in other animals is to humans, the more likely they are to be infected.
Unfortunately, ace2 receptors in cats are similar to humans, so cats are susceptible to infection.
In addition to cats, there are many potential susceptible animals in nature, such as otters.
Can a cat infect a person or other animal?
First of all, if the cat is infected with the new coronavirus does not mean that the disease will occur.
Viruses have different mechanisms and damage to different species, and different species have different immune systems, so the effects of the same virus on different species may be completely different.
Bats, for example, contain hundreds of viruses, many of which can cause fatal damage to humans, but bats are not well-lived.
There is no research to prove the extent to which the new coronavirus infects the cat to what extent.
Second, even if a cat is infected with the new coronavirus, it doesn’t mean it can pass the virus on to humans.
For example, a coronavirus in a bat can spread in humans after it mutates, but it is almost impossible for a new coronavirus to infect a human.
There is no evidence that cats can transmit the new coronavirus to humans. The intermediate host of sars, the beaver, was also infected after humans ate its meat.
Is it scientific that many people see this place and start talking about cat color change, and even more so they have abandoned their love cat?
Is it really scientific to abandon cats?
First, cats are susceptible to new coronavirus is the result of laboratory tests, not equal to the reality of cats are vulnerable to infection.
Laboratory tests use viral doses that are far superior to the actual environment.
In the actual conditions it is difficult to appear laboratory conditions, even if a bottle of poison, the dose is not enough, will not be out of the “cat” life.
So don’t worry.
Second, there is no evidence that the new coronavirus spreads largely among cats.
Professor Shi Zhengli, Professor Jin Meilin of Huazhong Agricultural University, collaborated on the paper, collected 141 cat serums from Cats in Wuhan for testing, of which 102 were collected after the outbreak of the new coronal outbreak and 39 were collected before the outbreak.
The results showed that 15 cats (14.7%) tested positive for the receptor binding domain (RBD) of neo-coronavirus.
These infected cats are caused by close contact with patients with new coronary pneumonia or potential patients, indicating that at best, people can infect cats.
Crucially, the cats showed no symptoms at all and did not spread the infection on a large scale.
Regarding this statement, Shi Zhengli team: Cat infection is misreading, there is no evidence of cat infection.
Third, abandoning cats will have a series of more serious ecological consequences.
Cats are more likely to acquire game than their owners’ food.
Stray cats (who don’t need to be fed by their owners at all) have about four times as much hunting power as pet cats. Stray cats prey more than 200 grams of prey, posing a threat to many birds and small mammals.
According to the American Bird Association, cats are the birds’ number two killers, second only to habitat destruction.
Stray cats can seriously damage local biodiversity, especially bird diversity, which is a safe and secure human health.
How to protect yourself and cats in daily life?
During the outbreak, daily protection can not be less: wash your hands frequently, watch the cat.
Once your owner is infected, remember not to touch the cat and not discard it.
In addition, people in isolation period do not touch the cat, so as not to infect the cat, it is recommended that the cat also home isolation.
In short, there is no evidence that the new coronavirus can spread on a large scale in cats, let alone that cats can spread the virus to humans, and the consequences of abandoning cats are clear.
Be kind to your cat and don’t abandon your self-ignorance.
