Halle, a biology professor Ke Kule (Alexander Kekule) said: "We do not understand why the H7N9 virus will cause this strange infection in the human body." Compelling scientific theory is easy, especially between poultry borne viruses rarely spread from poultry to human body. This new type of H7N9 virus seems to overturn this claim. Biosafety Institute Ke Kule explains: "The virus in birds who almost do not see any signs of sick." Not aware of birds or infected with the virus, so the chicken with the H7N9 virus duck poultry or pigeons consumption risk.
Ke Kule say a disturbing message: "According to the genetic analysis we can conclude that the virus must have been in humans or other mammals, such as pigs, latent for some time. "
The virus during the incubation period to adapt to the new environment, and choose the best shelter in the human body - Hu respiratory tract.
April 1, WHO has reported, for the first time this new type of avian influenza virus in eastern China was confirmed in three patients contaminated by the H7N9 virus. Subsequently about a month, WHO issued the number of infections has risen to 126 cases and 24 deaths. According to the authorities, this is a deadly influenza pathogens. Some Asian countries have introduced tougher airport screening measures.
The spread of the epidemic
Experts are facing a frightening problem: this new type of avian influenzavirus will trigger a large-scale epidemic around the world, resulting in millions of deaths. This does not have a clear answer.
A flu virus must occur gene conversion, an easy human-to-human transmission of the virus to be able to cause a worldwide pandemic, experts believe that the H7N9 virus has not this happens.
According to WHO, so far there is no indication that the persistent interpersonal communication. But one thing is sure, stained with H7N9 patients, some patients had not been and poultry have been in contact. The Keku Le concludes: "So, the way of the virus in other mammals, or the possibility of human-to-human transmission is very large."
But the virologists think H7N9 is far less than the extent of the terrorist virus: "The virus must be experienced in order to achieve the multiple genetic changes cause the extent of the pandemic." Ke Kule optimistic It added that, so far, has not monitored H7 viruses in the human spread of the phenomenon.
Faces an uncertain future
Robert Koch, the (Robert-Koch-Institut) Suzanne Grice Mach, Susanne Glasmacher stressed that an avian influenza virus gene changes the direction of the interpersonal communication, and can not make predictions this.
The current H7N9 virus and the H5N1 avian influenza virus in a few years ago. We have seen the killing of animals due to the impact of the H5N1 avian flu, poultry farms in Germany. Since 2003, world- wide, more than 370 people died of the H5N1 avian influenza virus. And the incidence of H5N1 symptoms similar to suffering from H7N9 avian influenza disease poison the patient's onset of symptoms, including severe pneumonia. The typical clinical manifestations there are high fever, and on Hu respiratory tract infections and Hu dyspnea. WHO said that there are some patients, the symptoms are not obvious. http://www.aboluowang.com/2013/0502/302997.html?utm_source=dlvr.it&utm_medium=twitter#.UYHdnLVwe8A
