The World Health Organization, 20 may update the official website of avian influenza report, published on the avian influenza virus of the latest discoveries. According to the latest content, H5N1 avian influenza virus in cold weather can survive in bird faeces for more than a month, even during the hot summer, also survived the past weeks. In addition, at the conclusion of human infection with avian influenza viruses, the report also proposes three main questions.
Tenacious vitality
Official website of the World Health Organization, the updated report that bird droppings are the avian flu virus in poultry and poultry and human communication channels between the main.
Who said that the avian influenza virus tenacious vitality. Website for example: "in low temperature conditions (4 ° c), the highly pathogenic H5N1 virus can survive in bird faeces for at least 35 days. At 37 degrees c under high temperature, the H5N1 virus can survive in bird faeces in 6 days. ”
Who said that the avian influenza virus has resulted in a record, the avian and human common infection in the largest epidemic outbreaks. From the South-East Asia to Turkey, the Ukraine and Romania, many countries have found that avian infection with avian influenza virus. According to who statistics, excluding Turkey recent deaths and cases of infection, global has 149 human infection with avian influenza viruses, including 80 deaths.
The incubation period is longer
Avian influenza viruses are not only strong vitality, and incubation period than the ordinary flu viruses must longer.
Who says, and General seasonal flu virus, H5N1 avian influenza virus incubation period is longer. Ordinary flu incubation period is approximately 2 to 3 days, the H5N1 virus infection cases show that its incubation period from 2 to 8 days, or even up to 17 days.
About human infection with avian influenza illness symptoms, reported that the initial symptoms include the onset of high fever, the body temperature is usually higher than 38 ° c, and other flu-like symptoms, "the early symptoms in some patients also have diarrhea, vomiting, abdominal pain, chest pain, nasal cavity and gingival bleeding".
Who said that infection with the H5N1 virus, all patient's condition soon developed into pneumonia. "According to existing clinical records, in the early days of onset of symptoms for about 5 days later, the patient begins to breathe. Respiratory irritation, hoarseness, breathe in alveolar tone sharp and other symptoms are also very common. "Some patients have a blood smear.
The other common symptoms are in multiple organ dysfunction, especially kidney and heart.
Who said that poultry is the main source of avian influenza viruses, particularly small homes flocks. "These bird often wander wild bird feeding, and the juxtaposition of or shared water sources. This situation increased human exposure to avian influenza virus, especially when the weather is not good for poultry owners enter the room from the courtyard, or let the children play or poultry into a place to sleep. ”
Three major mysteries
Who report presents three questions. Reported that the questions now are still not fully explained.
First, there are not many poultry outbreak area. Most infections occur in feeding poultry numbers does not many suburban and rural families.
Second, "high-risk groups," little incidence. Often considered high-risk population of commercial poultry farms workers, live market staff, poultry slaughtered workers, veterinarians, and lack of adequate protection in cases of medical staff take care of the sick, in fact, very few cases of infection.
Thirdly, young people are more healthy. Infections occurred in the health of children and young adults, so baffling.
Red wine may fight avian flu
Italy medical scientists study found that red wine contains a molecule effective against including avian influenza, influenza virus, the virus becomes blocked. Experts: the discovery to curb the current adversity steep important avian influenza outbreaks.
By Italy advanced health, several institutions of joint study found that the wine will not only help prevent heart disease, Alzheimer's disease and cedar, Dickinson's syndrome as a molecular help against including avian influenza, influenza viruses, and prevents the virus mutated adult-to-human transmission.
Experts: the results of the fight against avian influenza is extremely important, 1918, causing millions of deaths "Spain flu" virus is an avian influenza viruses and variations. Experiments show that wine can suffer from colds and mouse down 60% reduction in mortality. The scientific community also found liquor also contains a resistant material.
