How do we get the flu?
The influenza virus is transmitted from person to person. It could be transmitted via the air when a person sneezes or coughs. Or when we touch something contaminated with the virus. (For example, when we put our hands on a door handle contaminated with the virus).
Many times, we get the flu when the virus touches our hands, and then we put our hands on the mouth, nose, or eyes. The virus might reach our hands when we shake hands with a sick particular person or touch something like a glass, doorknob or telephone that the infected person touched. This is why you must wash your hands if you do not want to be sick.

Type A is often essentially the most harmful and has the most severe signs and symptoms in humans. And every year a new strain comes out that differs from the previous year. This is why you need to get a new flu shot every year.
Sometimes the completely different strains of influenza are named after letters and numbers. flue viruses of type (A) have the letters H and N in the name to denote the scientific terms (hemagglutinin) and (neuraminidase). An example of this is the H1N1 virus (which caused the Spanish flu in 1918.
