Although wild birds are carriers of the virus is usually not affected, the swine flu symptoms. They are domesticated birds (chickens, ducks and turkeys) in which the symptoms of avian illness and sometimes death. The symptoms of bird flu in poultry in May may be what springs rough and low egg production or a serious disease, multiple organs and death in herds 90-100% in just 48 hours. It is estimated that the degree of difference in the swine flu symptoms is the strain of the flu virus, which infect birds.

The symptoms of bird flu usually does not occur in humans, but 239 cases were reported in humans since 2003, according to statistics provided by the World Health Organization (WHO). 140 deaths in the world were for the symptoms of bird flu.

The people with bird flu, the symptoms were, in many countries of Asia and the Middle East, but most were in small towns and regions in Indonesia and Vietnam. Most cases of bird flu in humans, the symptoms result from contact with infected poultry or surfaces of fluid and feces of infected birds. The symptoms of bird flu in humans are the symptoms of influenza, including fever, sore throat, cough and muscle aches. But in some cases people have been confirmed bird flu symptoms of eye diseases, pneumonia, serious respiratory infections, acute respiratory distress and other complications. The Center for Disease Control (CDC) estimates that the number of symptoms of bird flu in humans in May will depend on the virus strain of avian influenza infected birds to the person.

The symptoms of bird flu is not sufficient for the diagnosis of avian influenza in humans and birds, because the symptoms of bird flu are very similar to the typical symptoms of influenza and other viral infections. For a diagnosis of bird flu in humans, a cotton swab through the nose or throat must in the first days after the symptoms of bird flu rating or two blood samples must be made to the presence of the H5N1 virus. For a number of flu in birds. Only influenza H5N1 virus is considered serious symptoms of bird flu which led to the deaths of more than 50% of cases.

Although highly contagious among birds, the symptoms of bird flu is not easily from person to person. The only case of bird flu confirmed by contact with an infected person was a member of the family remained in close contact with the person with symptoms of bird flu. It is different than the seasonal flu and the crisis of the SARS virus is highly contagious to humans. Looking for a pandemic (spread around the world) is because the viruses mutate. Therefore, if the bird flu virus in birds can mutate with a high around the world during an outbreak of bird flu, the symptoms May.

If you do not have contact with birds infected with the virus of avian influenza and that you will not worry the people who have the virus of avian influenza, and not the development of symptoms of bird flu virus, currently. If the virus can mutate form occurs, you have serious symptoms of bird flu in the same way as you are before the flu. If there is no reason why it is safe, which is probably the same virus caused slight or moderate symptoms of bird flu in some people and death in others, it is known that human immune system against influenza may be more errors in every 7-10 days.
