What is the influenza virus?
It is a respiratory virus because it infects the respiratory tract including the nose, mouth, bronchi and can
even go further into the lungs to the alveoli and cause pneumonia. A person will spread the virus
through coughing or sneazing that become airborne droplets. When a suceptible person comes in
contact and breathes in these droplets, it causes an infection.
Explain specifics of Influenza virus
There are projections on the influenza virus called hemagglutinin and neurominidase. hemagglutinin
allows the virus to attach and stick to the cell surface. Once the virus has replicated the nuerominidase
allows the virus to leave so it can infect other cells and destroy the cell it leaves
