(Fighting new crown pneumonia) Hong Kong's first suspected new crown pneumonia patient-transmitted dog medical expert: incidental
China News Agency, Hong Kong, March 5 (Reporter Han Xingtong) Recently, the first suspected case of human transmission of dogs with new crown pneumonia occurred in Hong Kong. A dog of a confirmed patient was tested repeatedly and showed a weak positive response to the virus, with a low level of infection with the virus. In this regard, some medical experts accepted the interview of the China News Agency that the transmission of humans was indeed "possible," but it was an accidental incident, and appealed to the public not to panic.
A spokesman for the Agriculture, Fisheries and Conservation Department of the Hong Kong Special Administrative Region (AFCD) confirmed on the evening of the 4th that a dog had a weak positive reaction to the virus in repeated tests of the new crown pneumonia virus. The results showed that the dog had a low level Infected with the virus, but it does not have any related symptoms and is undergoing quarantine.
In this regard, Yuan Guoyong, Chair Professor of Infectious Diseases, Department of Microbiology, Li Ka Shing School of Medicine, The University of Hong Kong believes that this case is a bit strange. If the dog is only polluted by the environment, its sample should be negative to the virus in one to two days, but if the infection is diagnosed The test results should be more than weak positive. He believes that humans have a greater chance of transmitting dogs, but details can only be determined after genetic sequencing.
He Bailiang, director of the Center for Infection and Infectious Diseases of the University of Hong Kong, said that the virus is transmitted from person to person, and other mammals may be infected, but even if the virus is transmitted from human to dog, it does not mean that cats will also be infected Call on the public to calm down. He Bailiang recalled that during the "SARS" period in 2003, cats and dogs diagnosed with patients in Amoy Gardens were tested for genetic viruses. Among them, 8 cats and 1 dog were positive for the virus, but there were no animal groups around the world that year. In the outbreak, cats and dogs were not found to be the source of the virus, and the virus was passed on to humans.
Dong Tang Jisheng of the Hong Kong Medical Association told a reporter from China News Agency: "Human transmission objects and animal infections may occur in many infectious diseases, such as 'SARS' suspected that the virus was transmitted to humans by bats and civets," but he It is emphasized that the dog's weak positive response to new coronary pneumonia is "individual and occasional," and urged the public not to worry too much or even panic.
There are many high-rises in Hong Kong, and the population density is high. Many citizens like to keep pets. Tang Jisheng believes that in theory dogs are more susceptible to infection than humans, "because they eat on the ground", so the occurrence of cases also reminds Hong Kong people with pets not to ignore animals and may be infected. In addition to paying attention to personal hygiene, The floor is often disinfected with 1:99 diluted household bleach at home; if you go out to walk the dog, try to wear a mouth cover for the dog to avoid their contact with the ground and reduce the chance of infection.
