Expert: guard against human influenza virus and avian influenza virus recombinant variant 2009-12-09 10:01
Human influenza virus, mutation, infection not long ago, "first found in China dog infected with a flow "have aroused widespread concern some people worried that exacerbate the epidemic spread of a stream, but also some people worried that a stream will be spread among animals, and will generate a new epidemic. A flow of the Ministry of Health Clinical XU Xiao-yuan, deputy head of the Group of Experts explained that although the cats and dogs and other animals can be infected with a flow of the virus, but does not like the birds in the rapid spread of the virus among populations.
LONDON December 9 News: Not long ago, "China's first dog was found infected with a flow" have aroused widespread concern some people worried that exacerbate the epidemic spread of a stream, but also some people worried that a stream will be spread among animals, and will generate a new epidemic. Please pay attention to --
November 25, Ministry of Agriculture, China Agricultural University, received a report that the school of Veterinary Medicine Clinical Hospital from the 52 dogs nose and throat swab samples in the incidence, and the detection of two samples was positive for Influenza A H1N1 influenza etiology. Concerned that this was my first detected in dogs infected with a stream. For the first time that China found in dogs infected with influenza, experts said the most likely transmitted from person dog, but also may be a dog pass the dog situation.
In dogs, the virus body found in a stream, does it mean that the virus virulence and transmission enhancements? In this regard, the Ministry of Health experts explained that cats, dogs are all that can be infected with a flow of the virus, this time in dogs to test out a flow, not to say that the virus variation, please do not be overly concerned about the public.
A flow of dogs infected will infect humans
Ministry of Agriculture is responsible for a person, from the current state of some of the cases, the U.S., Canada, Belgium and other countries have detected human infection with the virus and then infect animals situation. Which, in turn, animals, humans, the situation, the international studies are still not yet have a clear conclusion.
In his view, the dogs infected with influenza A H1N1 influenza virus, most likely by a dog or dogs have had close contact with the influenza A H1N1 infection influenza patients. The person in charge said that a dog infected with influenza A H1N1 influenza will be transmitted to neighboring dogs.
A flow of the Ministry of Health Clinical XU Xiao-yuan, deputy head of the Group of Experts explained that although the cats and dogs and other animals can be infected with a flow of the virus, but does not like the birds in the rapid spread of the virus among populations. On the contrary, cats, dogs and other animals, is not an easy communication between groups A stream. The cats, dogs and between, but not easy to spread the virus.
Before, there are already reports that other countries in pigs, cats have the virus found in a stream. Some experts also said that these cases from the foreign point of view, the U.S., Canada, Belgium and other countries have detected human infection with the virus and then infect animals situation.
For by what means the dogs infected with A stream, XU Xiao-yuan said the need for further study.
A flow of people and dogs were suffering from normal
"In fact, influenza is a 'zoonotic disease,' flu virus found in cats and dogs is not surprising." Guangdong Provincial Center for Disease Control Epidemic Institute Jianfeng pointed out, the flu has always been a zoonotic disease, the main is a mammal susceptible. In the past, pigs, cats, dogs and other animals, have detected other types of influenza viruses. A stream as a new type of influenza virus is no exception, so no need for panic.
Like the pet of the "Owners", "cat owner" Do you want to guard? He Jianfeng that the current pass in the end is a human dog, or the dog to pass people, have been inconclusive.
"There are no strains found to attack and attack dogs were the same strain, we can not prove that such a flow of strain can be transmitted between humans and canines." Prevention and control of the Group of Henan Province, deputy head of a stream, Provincial People's Hospital, chief physician mahi, Tao said that even if a dog can be transmitted to humans, transmission rate is also lower than the rate of transmission between people.
"A flow mainly through respiratory droplets spread, people in theater to see movies A flow rate of transmission, but also much larger than the spread of the rate of human pet."
"But now the A peak flow through the air transmission of the 'person to person' is still the main mode of transmission. So do the public are mainly self-protection and wash their hands more ventilation, less late at night, must also pay close attention to the health of pets Once abnormal seek medical attention promptly. "Jianfeng be emphasized enough.
Guard against avian flu mutation re -
PLA Influenza A H1N1 influenza joint prevention and control checks on members of the Group, the Air Force General Hospital, Infection Control Branch, director of Cao Jingui that both the flow found in people suffering from a virus after the dog, or prior to transmission to pigs, are not terrible, just one case, two animals with the virus mutates is another matter. Worthy of attention is the human influenza virus and avian flu virus re-occurring mutations.
"The virus transmission to pigs, dogs, in fact a kind of organizational compatibility issues. In medical experiments, many experiments with dogs, pigs, rabbits, rats do, and this shows a lot of virus in some animals and people who are compatible. "Cao Jingui said, therefore, a stream of people pass on the virus, whether animal or animals to people, from a medical point of view, are not too horrible thing. In addition, a flow rate of the virus to death is not high, even if small variations are not particularly big problem, without too nervous.
However, the Chinese Academy of Engineering, Zhong Nanshan, director of the Guangzhou Institute of Respiratory Diseases has once again issued a warning that a stream in the prevention and control, while doing a good job, but also should be wary of a re-flow and mutation of avian flu, "If this phenomenon occurs, for the human impact will be catastrophic. "
WHO's latest figures show that the global flow of A confirmed death toll reached 7826 people died within a week, an increase of 1076 cases, this figure has been far more than bird flu. Today, China confirmed its first case a dog infected with A stream, compared to the previous chicken birds were carrying the avian flu virus, said Zhong Nanshan, a stream, if and avian flu would be a major disaster recombinant variant. So, a dog infected with A in China confirmed its first case flow, compared with chickens carrying the avian flu virus is more terrible.
"Now, there including Hong Kong, the report A multi-country and regional variation of the phenomenon of flow." Zhong Nanshan, does not exclude the possibility of this phenomenon on a large scale, he said that the high fatality rate of avian flu, we must guard against a stream and birds Recombinant avian flu mutation possible. Such a situation arise, it will be a very big disaster.
Meanwhile, vice president of the Hong Kong College of Medicine Sung also revealed dogs and cats infected will increase the opportunities for the spread of SARS, so that higher risk. He said that if a close human contact with animals infected with a stream, will increase the risk of virus outbreaks, this situation as an outbreak of bird flu among chickens like. "If cats and dogs and other pets were infected with the human A stream will be greater risk to humans." He said, not without concern. :tiphat:
