Influenza commonly called the flu is a virus. Flu season runs from October to March. Actually itís many viruses and can be found on many strands. The three types are A, B, and C. Type A which is the most common leads to the most serious epidemics. Type B can cause epidemics and usually produces a milder disease with type A. Then thereís type C, which is associated with the symptoms suggesting a common cold.

It was the work of Dr. Salk and Dr. Francis in 1944 that lead to the discovery of the flu vaccine. The vaccine takes up to 2 months to fully take effect. There is however many strains out there that the vaccine wouldnít prevent them all. Amantadine, rimantadine, oseltamirir, and zamimarir are the 4 drugs that you can get to also help prevent influenza.

Influenza can spread in two ways. It can spread through the air. If someone coughs around you that has the flu then you can potentially get the flu. The other way is by toughing an area of an infected person that has that virus on it and then touching your own eyes or nose or somewhere on your own body. You could shake a personís hand and then get the flu.
