A/H5N1 flu outbreak in humans threatened
Tuesday, 08/14/2012 21:40
The transformation of the avian influenza virus in the vaccine is disabled patients have an increased risk of virus to mutate, spread from person to person
Mr. Nguyen Van Binh, Director of Preventive Health (MOH), said the bird flu are recurrent in some provinces such as Quang Binh and Ha Tinh and Hai Duong, Hai Phong and Ninh Binh is raised on flu fears
A/H5N1 in humans. If people have no sense of preventing the risk of transmission to humans is very large.
Potential risk of transmission
According to Binh, from the beginning of the year, the country has discovered four cases of influenza A/H5N1, including 2 deaths. These cases were discovered in the early months of 2012. This is also the time of influenza outbreaks in poultry.
Meanwhile, the Veterinary Department (MARD), explaining the results of analysis show that the latest gene appears branch new bird flu virus in North, Central and Western Highlands. The emergence of new strains means that the protective effect of the vaccine before a new strain of bird flu this decline, only 35% -40%.
Prof. Dr. Nguyen Tran Hien, Director of the Institute of Hygiene and Epidemiology, said that when the vaccine is not effective for prevention of diseases in poultry, the virus will quickly adapt and can easily spread to humans. According to Hien, another factor is particularly concerned that people just discovered the phenomenon of translation as dead sick poultry, and fresh bird flu virus is often overlooked because there is no manifest for identification. This is considered the most difficult to control pathogens and potential risk of transmission from poultry to humans.
Experts assess the epidemiology always appears at risk of additional cases of influenza A/H5N1 by husbandry practices of the people and practices in slaughtering, meat and poultry, especially duck dishes .
People do not have immunity to influenza A/H5N1
Dr. Nguyen Tran Hien identify the origin of A/H5N1 flu cases have originated from birds. More than 60 cases of death from this virus are largely related to breeding, slaughtering and eating infected poultry. However, until now, scientists have not developed the mechanism of virus transmission from poultry to humans, which just made the possibilities of the spread. It is the H5N1 flu virus in poultry can infect humans by inhalation of droplet viscosity ranges, respiratory secretions and digestive tract of sick chickens or by breathing air with dust from chicken manure, bird droppings , dried secretions carrying the virus alive. In addition, influenza virus in the dirty hands, food, water pollution ... can also go into the mouth, thereby entering the respiratory tract and cause disease.
Due to weak resistance so children are very susceptible to virus objects
Experts said the risk of human disease are nearly the same as the causative agent of this people do not have immunity. "However, the investigation of healthy people in the area poultry, waterfowl, we found a small percentage of healthy people carry the infection without active disease. But because the rules are unclear and the degree of sensitivity should be alert everyone "- Mr. Show said.
According to Dr Nguyen Van Kinh, Director of Tropical Diseases Hospital Central, this time though not detected any cases of A/H5N1 flu, but people should not be subjective. By 2 deaths from influenza
Earlier this year due to A/H5N1 were neglected after nearly two years without new cases. Mr. Glass said that the two deaths have been diagnosed and specific treatment when influenza was later stages, rapid changes should not survive. Treatment with Tamiflu after 3 days of onset and reduce the likelihood of drug response.
"I am not saying that is encouraging people to reserve and self-treatment with Tamiflu before the effects of the H5N1 flu virus. These medications such as Tamiflu should be prescribed and the doctor indicated in each case closely to avoid specific adverse effects "- Dr. Glass said.
Symptoms similar to dengue fever
According to Nguyen Van Binh, A/H5N1 flu and dengue fever are infected with the flu, but when the disease is usually a high fever with continuous cough, chest pain, difficulty breathing, runny nose, while with dengue but then the fever presents with bleeding under the skin. With the situation as at present in poultry, especially people living in endemic areas, if any of the above expression should be to the medical facility for treatment soon. Changes often have severe disease, especially in the elderly, children, pregnant women and those with chronic diseases (cardiovascular, pulmonary, renal, metabolic, immune insufficiency).
