Influenza, known in English (Flu) is a disease caused by viruses that normally infect the respiratory system, and comparing most other viral infections of the respiratory system such as the common cold (Common cold), the influenza infection often causes severe fatigue.
Influenza viruses change over time ie there is no one particular virus or more of the specific virus activates or injured by a human viruses constantly changing. This change can be hard virus that invades and attacks the immune system, so person gallery throughout his life for influenza virus infection.
Cycle of human infection with influenza are as follows:When a human influenza virus consists of antibodies against this virus, including the ever-changing virus antibodies old do not recognize the new virus and infection occurs again again. But despite this, the antibodies can provide the patient with partial protection in the new stage of infection.
And diffuse three types of influenza viruses in the world:Two belong to the virus (a), and one type belongs to the virus (b).
Where divided viruses (a) to sub-types or also called categories or strains (Strains), and supports this difference on the quality of the proteins found on the surface, where there are two types of proteins (Hemagglutinin / H) and (Neuraminidase / N), and symbolizes subtypes numbers such as: (H2N1 & H3N2).
And pass influenza viruses (a) two kinds of changes, one series of changes that occur over time and cause the emergence of a gradual of the virus and this so-called drift or gradual transition anti-genes (Antigen drift) The other type of change is the sudden change in proteins is the so-called transport or move sudden anti-genes (Antigen shift) In this case, a new subtype appears suddenly to the virus.
