Influenza (Avian and other zoonotic) Avian influenza is a viral disease that can affect bird species throughout the world. The disease can vary from mild to severe, depending on the virus strain involved. The most severe strain, called highly pathogenic avian influenza (HPAI), is caused by viruses with H5 or H7 surface proteins.

Questions & Answers The H5N1 virus is the strain of avian influenza that has infected numerous species of birds in Asia, Europe and Africa since the end of 2003. It has not been found in birds in North or South America, including the Caribbean.

- Carriers may spread the infectious bacteria to other adult birds or to their offspring; the babies usually become acutely ill and frequently die. Acutely ill birds, whether juvenile or adult, often have ruffled feathers, diarrhea, listlessness, weakness, shivering, or vent picking. The degree of illness depends on the age of the bird, the strength of the bacteria, stress and other factors.

Avian Flu (Bird Flu) Symptoms in Birds & Humans These precautionary measures could reduce the possibility of infection with avian and human influenza viruses. Avian Flu Symptoms for Humans: All poultry workers should know the signs and symptoms of avian influenza virus infection in humans so that measures can be taken for immediate treatment. The signs and symptoms may include fever, cough, sore throat, conjunctivitis (eye infections), and muscle aches. Infection with avian influenza viruses can also lead to pneumonia, acute respiratory distress and other severe and life-threatening complications.

- No. Avian influenza is primarily a disease of birds. It is caused by influenza viruses closely related to human influenza viruses. Transmission to humans in close contact with poultry or other birds occurs rarely and only with some strains of avian influenza.

Types of Bird Flu, Avian Flu Transmission Infection with certain avian influenza A viruses (e.g., some H5 and H7 strains) can cause widespread disease and death among some species of domestic birds. Since 1997, several outbreaks of H5 and H7 influenza have occurred among poultry in the United States.

Questions and Answers on Avian Influenza (âBird Fluâ) Some other species of birds are known to pick up avian influenza from poultry. In the case of H5N1, the disease is so severe that the other birds will often die before they spread it over a wide region. In the 2004-2006 outbreaks, some people thought the Asian form of avian influenza could be carried to the United States by wild birds flying from Siberia to Alaska. It didn’t happen.

Pandemic It is feared that if the avian influenza virus combines with a human influenza virus (in a bird or a human), the new subtype created could be both highly contagious and highly lethal in humans. Such a subtype could cause a global influenza pandemic, similar to the Spanish Flu, or the lower mortality pandemics such as the Asian Flu and the Hong Kong Flu.

Influenza Most references in the media to bird flu and most references to H5N1 are about this specific strain. At present, HPAI A(H5N1) is an avian disease, and there is no evidence suggesting efficient human-to-human transmission of HPAI A(H5N1).

- Bird flu, or avian influenza, is an infectious disease of birds caused by type A strains of the influenza virus. Bird flu epidemics have occurred worldwide. Bird flu is a leading contender to be the next pandemic flu bug because it has caused an unprecedented epidemic in poultry and wild birds across Asia and Eastern Europe.

Influenza A virus subtype H5N1 However, there is some evidence the actual mortality rate of avian flu could be much lower, as there may be many people with milder symptoms who do not seek treatment and are not counted. In one case, a boy with H5N1 experienced diarrhea followed rapidly by a coma without developing respiratory or flu-like symptoms.

Avian influenza Avian influenza. For the H5N1 subtype of Avian influenza, see Influenza A virus subtype H5N1. Avian influenza — known informally as avian flu or bird flu — refers to influenza caused by viruses adapted to birds.. The type with the greatest risk is highly pathogenic avian influenza (HPAI). Bird flu is a phrase similar to swine flu, dog flu, horse flu, or human flu in that it refers to an illness caused by any of many different strains of influenza viruses that have adapted to a specific host.

It is the most dangerous virus known, to any animal. Avian Influenza is extremely lethal, wide-spreading, and commonly has acute symptoms; it is a virus every chicken raiser and non-chicken raiser should know well. This virus is wide-spreading and makes chickens drop like flies.

Influenza Influenza, commonly known as the flu , is an infectious disease caused by the influenza virus. Symptoms can be mild to severe. The most common symptoms include: a high fever, runny nose, sore throat, muscle pains, headache, coughing, and feeling tired.These symptoms typically begin two days after exposure to the virus and most last less than a week.The cough, however, may last for more than two weeks.lu symptoms in birds are variable and can be unspecific. The symptoms following infection with low-pathogenicity avian influenza may be as mild as ruffled feathers, a small reduction in egg production, or weight loss combined with minor respiratory disease.
