On the 28th, the Agriculture, Fisheries and Conservation Department of China (AFCD) issued a notice that a dog living in the home of a person diagnosed with new coronary pneumonia had tested positive for the virus. Afcds said that although there was no evidence that the pet would become infected or to spread new coronary pneumonia, the department monitored the dog closely and further samples were taken to ascertain whether the dog was infected with the virus or that his mouth and nose were infected with the virus from the environment. AFCD will continue to conduct repeated tests on the dog until it has tested negative.
In response, Dr. Maria Van Kerkhove, technical director of the World Health Organization’s emergency program, said at a press conference on the 28th that the situation was known and was working with hong Kong authorities and scientists in China, where dogs were being tested.
“Trying to understand these results and see where the dog actually became infected or whether it was actually infected, or whether the dog was caught from a contaminated place. “So we’re working with them to understand the results, what further tests they’re doing and how they’re going to take care of these animals,” Mr. Van Kirkhof said. We will answer the question again in the future and provide some practical answers to this. “
Previously, the WHO published on its official website in the form of a “rumour shredder”, “There is no evidence that dogs, cats and other companion animals / pets are infected, and there is no evidence that they can infect the new coronavirus.” “
New crown patient’s pet dog tested weak positive
Afcdling explained in its announcement that on 26 February, it received a referral from the Department of Health that the dog in the home of a person diagnosed with new coronary pneumonia should be handed over to AFCD. AFCD officers picked up the dog at a shelter in Tai Tae on the same evening and were taken to the Animal Detention Centre at the Hong Kong-Zhuhai-Macau Bridge Port where samples were taken from their mouths, nasal cavities and anus for a new coronavirus test. Samples of the oral and nasal cavity were weakly positive in the test. The dog has no associated signs. A spokesman for AFCD also said that in order to ensure the health of the public and animals, the Department strongly recommended that pets (mammals) in the homes of those diagnosed with new crown pneumonia be quarantined.
As mentioned earlier, the WHO side is currently aware of the situation and is awaiting further test results to determine the dog’s own condition.
Earlier, on the evening of February 3, Hubei held the 13th outbreak prevention and control routine. At the press conference, Jiang Rongmao, a member of the National Health and Health Commission’s expert group, said the virus is a barrier, not that it can be crossed at will. “So far, we have not seen any re-transmission of coronavirus infection in pets, nor have we detected cases of cats and dogs that have been sickened by the infection of the coronavirus in patients.” He pointed out.
The same view was expressed by the many industry experts interviewed by First Financial. Ian Goodfellow, professor of virology at the University of Cambridge’s Department of Pathology, told First Business that there was no evidence that dogs or cats were infected with the new coronavirus: the spread of the virus was generally restricted by the host. Until there is any hard data, it is wrong to think that dogs and cats are vulnerable.
Not all coronaviruses can infect people.
Jiang Rongmao said that the current study shows that there are four genus of coronavirus, a total of more than 50 kinds, but even with the addition of a new coronavirus, only seven viruses are known to infect people. In other words, he points out, not all coronaviruses can infect people, and not all other animals can be infected.
Chen Manfu, a practicing veterinary surgeon in China, explained in an interview with First Financial That the new coronavirus belongs to beta, while the canine coronavirus and cat coronavirus are both alpha genus and cannot be transmitted to humans. Chen Manfu told the first financial reporter: “The vast majority of coronaviruses have a single receptor, so canine and cat coronavirus will not infect people, and vice versa.” “
“The main area of host for coronavirus is the S protein on the surface of the virus, which is responsible for binding to the host cell receptor, and the virus can infect the host,” Sun Honglei, an associate researcher in the Department of Preventive Veterinary Medicine at the School of Animal Medicine of The Agricultural University of China, told First Financial Reporter earlier. The new coronavirus is a human alveoli surface of the angiotensin conversion enzyme 2 (ACE2) as a receptor, and dogs, cats, rats, mice and other animal lungs do not have such receptors, so it is not possible to infect the new coronavirus, and vice versa, it is like a key to open a lock of the truth. “
The WHO notes that the animal source for the new coronavirus has not yet been determined, and that “an animal source from the Chinese live animal market is likely to be the cause of some of the earliest reported human infections.” In order to protect yourself, avoid unprotected direct contact with live animals and with animal surfaces when visiting live animal markets. Foods of raw or undercooked animal products should be avoided. In accordance with good food safety regulations, care should be taken to treat raw meat, milk or animal organs to avoid cross contamination with undercooked food. “
“However, after contact with pets, it is always right to wash hands with soap and water,” the WHO notes. “
