The Influenza virus kills about 36,000 people a year. The Influenza virus is a potentially deadly virus that attacks the respiratory system. It also leaves the human body very tired and weak. The Influenza virus mostly affects the respiratory system. The basic structure of the Influenza virus includes the Viral Envelope, Nucleoprotein (RNA), Neuraminidase (Sialidase), Hemagglutinin, and the Capsid. When the virus attacks the respiratory system, it causes fatigue, fevers, and chills. Ironically, this tiny non-living virus can have a tremendous affect on our bodies.
The Influenza virus attacks the Respiratory system, the Digestive system and the Immune system. A wide range of respiratory complications can be caused by the Influenza virus, infection of the upper respiratory tract (nasal passages, throat) and lower respiratory tract (lungs).
