A bird flu which is also referred to as avian flu may be simply described as any sort of influenza caused by viruses that are adapted to birds.

The subtype H5N1 is the most common causes of the avian flu that out broke recently in 2006. One very peculiar trait of this group of viruses is the infection it causes in birds does not result in any illness within the birds but on the contrary; being highly contagious they pose a great threat to humans when domesticated birds like turkey, chicken, and ducks are infected. The transmission of the viruses from the infected birds usually takes place through the saliva, nasal secretions and the feces.

Scientific researches carried out reveals that sometimes this subtype which generally causes mild disease in birds may also mutate into viruses that can cause serious and pathogenic diseases. The migratory water fowls and swans in particular acts as good vectors and carriers for the viruses. The exact incubation period for the viruses is yet to be revealed but it has been observed that the illness and the symptoms start developing within 1 to 5 days of exposure to the virus. A relative mild eye infection medically termed as conjunctivitis may be the only indication of the disease in some cases. Where as usually the symptoms bear resemblance to those of a conventional influenza some of which are cough, fever, frequent chills, headaches, a sore throat and pain in the muscles.
