Not detect cases of avian influenza A/H5N1 virus in Vietnam

6/9/12 (Reuters) - The arrival of new bird flu virus more dangerous in poultry causing many people to worry. Evaluation of new avian influenza virus, the World Health Organization said that this transformation does not increase the risk to human health. Accordingly, recently, the Ministry of Agriculture and Rural Development has announced the emergence of a new H5N1 virus in poultry. Compared with the H5N1 virus is still circulating earlier in their flocks, this new virulent virus are much higher. Assessment of the transformation of the A/H5N1 flu virus, Dr. Nguyen Tran Hien, Director of the Institute of about sich Epidemiology for that variation is not uncommon, but it is the change in natural evolution of the virus. Prior to that, from August / 2011, the International Food and Agriculture Organization has warned of the transformation of the A/H5N1 flu virus subgroup 2.3.2 in many Asian countries, including Vietnam ..

According to the research results of the H5N1 strain of the Institute of Hygiene and Epidemiology Vietnam shows that there alternative avian influenza virus subgroup 1 (before 2007) in Subheading 2.3. 4 (from 2007 to present). Since 2005, the A/H5N1 flu virus changes slightly, but basically virulent as before. "This is just a small variation of the virus to create a new branch, not major changes to create a new strain", TS Show affirm.

The World Health Organization (WHO) also said that this variation of the H5N1 virus does not increase the risk for human health. Accordingly, avian influenza on still takes place Sporadic and isolated in humans through contact with infected birds or the environment and do not have the virus is transmitted from person to person.

 In Vietnam, Hien confirmed cases of avian influenza infection in humans so far have not seen anything unusual. Although avian influenza infections in humans is not unusual, the transformation of the virus in poultry is natural variation in the natural evolution of the virus, but TS Show also gives warning strengthening monitoring the virus is circulating in birds to detect the change and provide appropriate strategies to control outbreaks in poultry and human health protection. "Because most worrying thing is that the A/H5N1 flu virus continues to circulate and cause outbreaks in poultry. It can further small changes, rearranging the genetic reassortment with other influenza viruses circulating in animals and humans to form a new flu strain highly virulent and capable of human-to-human transmission ", PGS Show said.

 To A/H5N1 flu, the Ministry of Health strongly recommends that people do not kill, Poultry sick, dying and birds of unknown origin. Do not eat duck, do not eat meat and poultry has not been processed. When symptoms such as fever, cough, shortness of breath related to exposure to poultry immediately to the nearest medical facility for examination and treatment In addition to strengthening food cooked boiled drinking, personal hygiene is also important to promote measures to prevent the spread of avian in as: implementation of biosecurity in animal husbandry, hygiene regularly disinfect cages with sterilizing drugs, vaccine for poultry, bird detection O, mass death must immediately notify the authorities ...
