In brief: Classification
Influenza viruses are RNA viruses that have segmented genome and have high antigenic diversity.
They are classified by a protein inside the virus (a, b, and c). Influ a is responsible for frequent annual outbreak and has more propensity for antigenic change. B causes outbreaks every 2 to 4 years. Influ c is known to infect human and pigs but it is rare

In brief: Genome
The viral composition is different among the 3 types.
Every year a is the most common virus circulating followed by b and then c. They also have different sensitivities to antivirals.
