ND - The Department of Health Preventive and Environment (Ministry of Health), on 12-3 confirmation of cases positive with the virus influenza A (H5) in Phu Ninh, Soc Son district (Hanoi). Patients are ventilation, treatment positive at the Faculty of treatment positive - Bach Mai Hospital. Investigate the epidemiology original shows, early March, the area around the patients had bird sick or dead scattered. On 11-3, Institute of Hygiene and Epidemiology Surgeons confirmed test results positive for the virus influenza A (H5). Thus, from the beginning of the year, the country has had four cases of influenza A (H5N1), in which one person died and a case of being treated positively.

Prof., Dr. Nguyen Huy Nga, Director of Department of Health Preventive and Environment received the, translated influenza A (H5N1) in people at risk of outbreak back to the sense of prevention of the people is not high, especially in a some local areas far still status slaughtering and eating of poultry diseases. After investigating epidemiology, most patients with a history of exposure to poultry disease. Meanwhile, the situation translated influenza in poultry in our country still appear scattered. Notified by the Department of Animal Health (Ministry of Agriculture and Rural Development), currently, both countries six provinces: Ca Mau, Nghe An, Dien Bien, Khanh Hoa, Tuyen Quang and Ha Giang with avian influenza less than 21 days. Nghe An Province is the latest recognition service influenza in poultry (on 28-2). Experts also are concerned, the existence of influenza A (H1N1), influenza A (H5N1) in humans and avian influenza, along with the weather winter spring are favorable conditions for the flu virus to develop and progress spread to many localities. With the existence simultaneously of the virus H1N1 and H5N1, requires monitoring closely the situation in epidemiology and conducting research for the risk of a combination of two viruses, the variables are the virus more pathogenic dangerous than very high.

Meanwhile, at the National Conference of activity prevention and pandemic influenza in humans, Dr Le Quynh Mai, Dean viruses, Institute of Hygiene and Epidemiology Surgeons said, through isolated more than 300 micro - virus influenza A (H5N1) in poultry and patients in the local experts have detected at least seven antigens in the virus bird flu since the viruses have in our country . The research team noted approval evolution of segments of genes between the genetic variations of flu virus, also detected with the exchange and integration between the virus influenza A (H5N1) circulation in our country ...
The analysis of molecular genetic material-virus influenza A (H5N1) in our country is that evolution is too fast the virus and are under strain highly pathogenic, with the change of antigen reduce the sensitivity of treatment flu. This is a matter dangerous to public health by the forecast of experts is not soon, then later, a new virus may appear from the recombinant of the vaccine viruses old and triggers a pandemic to the extent unpredictable.
