The scientists pointed out that the first discovery of the H7N9 avian influenza virus gene sequence data, this virus has certain mutations may will form a human pandemic.
There is no evidence of infection killing nine people including 3 people sick to death of the H7N9 infection between people, known in mainland China. This virus may gradually disappear, without complete mutation adult influenza-like illness. Canada homes
The mainland authorities announced that a number of H7N9 confirmed cases only after a few days, flu experts have laboratories around the world in search DNA sequence data of the patient samples to assess the possibility of a pandemic.
Aust House (Ab Osterhaus), one of the world's top flu expert, Netherlands, Erasmus Medical Center (Erasmus Medical Centre) pointed out that this virus gene sequences revealed that certain mutations, it is worth authorities alert The need to strengthen the monitoring of animal and human.
Aust House said in a telephone interview, "in a way, the virus has to adapt to mammals and human, for that matter, is worrying,"; "We should be really high degree of attention to this situation".
Kyodo News from the mainland reported that the H7N9 virus previously been regarded as a "weak toxicity" low public health risk, but the continent diagnosed infections are severe. Genetic Analysis results show that the patients found in the body of the virus as "strong toxicity.
Quoted Tashiro, Director of the Research Center of Japan's National Institute of Infectious Diseases influenza virus real argument that the H7N9 virus may occur genetic variation becomes accessible to human transmission.But the mainland of South China Agricultural University poultry disease research team, veterinary science, vice president Ren Tao has said from past experience to deal with the bird flu virus, H7N9 outbreak in interpersonal diffusion unlikely.
"Nanfang Dushi Bao" reported, Tao Ren, H7N9, although not in the human-to-human infection, but the H7 subtype influenza viruses from 1996 to 2009 in the Netherlands, South Korea and other countries has undergone human infection, the case of highly pathogenic avian influenza virus , but the range is very small.

He said, the public emergence of this new virus does not require too panic, previously infected with human H5N1 avian influenza virus, the number of incident cases in epidemiological history is minimal. http://www.iask.ca/news/china/2013/0404/190942.html
