Bird flu is a disease caused by H5N1, a type of virus that affects birds. It can also be seen in humans. It has caused many deadly epidemics over the years, especially in Asia. Bird flu usually spreads between birds and is transmitted to humans usually through direct contact. However, it is rare for the virus to spread between people.
Bird flu can be fatal. According to the World Health Organization, approximately 60 percent of bird flu cases in humans are fatal. However, this rate may vary depending on different strains of the virus and whether the disease is diagnosed early. Therefore, it is important to contact a healthcare professional immediately when symptoms of bird flu occur.
Bird flu symptoms include high fever, cough, sore throat, muscle aches and general malaise. In some cases, the disease can cause cough, shortness of breath and fatal pneumonia. These symptoms usually begin within the first few days after contact with the virus.
