Chinese Academy of Medical Laboratory Animal Research Institute Professor Qin Chuan reminder of human infection with H7N9 avian influenza prevention and control work can not be slowed because of public concern, and gradually fades, especially when in the autumn of this year, should exercise extreme caution and do prevalent prevention preparations.
Qin Chuan Association to participate in the 15th China issued during the annual meeting of the above reminder, she told reporters on the China Youth Daily, a large number of animal experiments from the lab results to determine, H7N9 avian flu is not concentrated in a short time scale outbreak , but may in the future continue to be popular, has now confirmed virus through mucous , saliva and other ways to spread among people in cohabitation.
At present, reported 130 cases of human infection with the H7N9 avian influenza in 26 deaths, Qin Chuan that 20% of mortality is too high for an infectious disease, the need to increase the strength of the virus as soon as possible to study, in order to reduce virulence and mortality.
World medical profession one of the most authoritative academic journal "Lancet" published an article confirmed that the chicken is infected with H7N9 avian influenza virus people one of the sources, while the H7N9 virus from at least four different birds obtain the virus genes, including Zhejiang duck, mallard Korea, Chinese chicken and wild songbirds, the virus is transmitted through infected through migratory birds to poultry ducks further infection in vivo.
Xinhua News Agency reported that an international research team of 23 in the U.S. "Science" magazine online edition said that animal experiments have shown, H7N9 bird flu virus can be spread by close contact to achieve effective, the researchers say, these findings indicate that H7N9 virus evolved further has caused large outbreaks of influenza may be.
The researchers said in a statement, because H7N9 virus can infect humans, pigs, ferrets and other mammals, so this virus prevention and control needs while taking into account other poultry, livestock and pets, the infected person or animal may appear higher concentrations before symptoms begin to detox, this may not be the typical symptoms of infection appear, therefore, epidemic prevention and control should never be taken lightly.
Qin Chuan judgment and the judgment of the research team have similarities: the future may be infected with H7N9 bird flu more and more people, even as common as the flu, but with the understanding of the virus, the consequences of human infection may be less pathogenic severe.
Qin Chuan in fifteenth annual meeting of China Association for Women in Science Forum, to do a "new and re-emerging infectious diseases Thinking - Animal Disease and Human Health" special report: In the past 25 years, from animal diseases transmitted to humans a total of 38 different kinds;
There are 1,407 kinds of pathogens can cause human disease, including viruses, bacteria, parasites, protozoa and fungi, these pathogens, 58% are from animals ; there are 177 kinds of pathogens once the "emergence" or "again", are likely widespread in humans.
For China, beginning from the 1970s, the average annual occurrence of one or more emerging infectious diseases. After 2000, there is a greater impact on China alone, there are SARS, H5N1 avian influenza, H1N1 avian influenza, foot and mouth disease, H7N9 avian influenza outbreak.
Pathogens is so easily spread among humans, Qin Chuan analysis related to lifestyle, now more densely inhabited, and more frequent exchanges, frequent pathogen spread more easily travel around the world, while a warming climate for the pathogen played a role in fueling the spread.
Removal has been known to the public the way, but let communicable disease risk factors include increased vandalism wildlife gathering area.
Large numbers of human activities in such areas, while damaging biodiversity while engaged in the illicit trade in animals, destroy the ecological balance at the same time put a lot of wild animals should not be brought to the table to eat.
Qin Chuan judgment, coming from animals to human disease is likely to be more and more, could seriously affect human health.
To this end, Qin Chuan call PETA, away from the source of infection. She objected to human and animal behavior are too close, wash hands after contact with animals, avoid wild animals into the community to prohibit overfishing killing, eating venison behavior, "There must be intimate with
animals between."
"We can not always the same as the firefighters to the disease on the block." Qin Chuan said that infectious diseases is reflected not only in the treatment, the root causes of the problem or biological harmony between human scientific quality.
