Re: Confirmed case of A/H5N1 in Ho Chi Minh City - 3 years old
Recently, the science has discovered as there is integration between the exchange v influenza A/H5N1 viruses circulating in Vietnam, creating too fast evolution of the virus strains are pathogenic v high. Number of H5N1 infections in three months in 2009 with the latest report by the Department of Preventive Health and Environment (Ministry of Health), from early 2010 until now, the country recorded five cases positive with Influenza A/H5N1 in humans, two cases of death. Looking back at the 2009, Vietnam recorded five influenza A/H5N1 infection v ca ca This is the fifth death, mortality l 100%, higher than double the previous year. So m is only 3 months in 2010, the number of people infected with both influenza A/H5N1 was in 2009, the number of deaths is approximately ? in 2009. Dr Le Quynh Mai - Virus Dean, Institute of Hygiene and Epidemiology PRIVATE said that recently, and as science has discovered there is a built-v exchange between influenza A/H5N1 virus circulating in Vietnam Creating a too rapid evolution of this virus v is the highly pathogenic strains. Experts have discovered a number of changes of antigen reduces the sensitivity of influenza treatment. Before this situation, again, the question about the possibility of a mixture of two types of influenza A/H1N1 virus influenza A/H5N1 v became hot issues. In the past month, the monitoring system of key influenza, cases of influenza A/H1N1 syndrome has decreased, only about 18% of samples tested positive for H1N1 in the previous figure is 80 l - 100%. However, Masters Nguyen Hong Ha, Deputy Director of the Hospital for Tropical Investment has estimated that the H5N1 virus from a few years now has always existed in the environment, even the poultry do not die but can still carry the virus. H1N1 virus was reduced but still exists, so, when H5N1 becomes strong, the risk of recombinant l still. "Influenza Virus no stability genetically. It has the ability of recombinant, sort v mutation is very high. Virus H1N1 short-lived but spread quickly from person to person. Virus H5N1gay high mortality but low ability to spread. If the combination, most likely will create a new virus more dangerous, just a quick spread of H1N1 from person to person, just high risk of death by H5N1.
Translate only discovered when someone infected? H5N1 virus in poultry exist then spread to humans. Review 5 ca influenza A/H5N1 infection in Vietnam since early this year, see: After investigating the residence of patients in Soc Son (H Nội) am 15 thirds, Chi H Civil Veterinary Department said, there are 60 sample serum translated almost v-throated birds negative for influenza A/H5N1 virus, still have not found the source of infection of patients. Patients with H5N1 infection in Binh Dinh (now died), the new functional bodies of local spread the disease to determine the source. Now patients in Khanh Hoa, patients have no family who are ill, not sick ducks g / die. But nearly a month before starting disease patients, e ostrich farm (located approximately 1 km as the patient) had e ostrich phenomenon unexplained death. Families of patients in Tuyen Quang is a sick phenomenon g / die but unexplained. Patients die in Tien Giang is a v slaughtering and processing aquatic birds before the disease but the area also have not been warned l disease. So, clearly, the collaboration between the Veterinary Medical v not close, most cases of influenza detected in humans before then v epidemiological surveys have detected the bird flu. Can he talk with Van Binh, Deputy Director Chi Chi H Civil Veterinary Department, he also admitted prevention poultry weak. Reasons given by l depends very much on the raising awareness: People do not bring birds to vaccination, we also bear! In addition, sub-department staff are difficult to control the number of all poultry consumed per day in H Noi for a limited number, lack of synchronization between local authorities v management market. Bad influenza A/H5N1 back also occurs in many countries around the world, not separate Vietnam. Recently, WHO also for the Ministry of Health in Egypt has recorded five cases of influenza A/H5N1, which has a severe case, there is no death. Thus, from the beginning of the year, Vietnam l only national recognition of deaths due to this virus. This trend, along with Indonesia, Vietnam l one of the two countries with many cases of death due to H5N1 virus one.
