Influenza A virus or more known to us as H5N1 is an avian (bird) flu, an influenza A subtype that has caused outbreaks in domestic poultry in parts of Asia and the Middle East. This is deadly to them and is considered “highly pathogenic” meaning highly disease causing. Although the virus does not usually infect people but infectious that these viruses occurred in  humans. Most of these cases have resulted from people having direct or close contact with H5N1-infected poultry or H5N1-contaminated surfaces.

There are three types of viruses, A, B, and C, that can cause flu to human. The type A is characterized not only to human but to other mammals and birds too. The virus transmitted by air. The type A virus is composed of two obligatory protein components. One is called hemagglutinin and is lettered H, and the other—neuraminidase (N). And there are 13 variants of hemagglutinin and 9 of neuraminidase, which then can characterized what type of virus it is. Making H5N1 is just out of the many possible variants of the virus structure.





The H5N1 virus does not infect humans easily and in general it remains very rare disease in people. If the person is infected it is not that easy to spread it to another human. However, there has been some human-to-human spread of the virus although it is limited
