Flu due to the type C species is rare compared to types A or B, but can be severe and can cause local epidemics. In epidemiology, an epidemic (from Greek epi- upon + demos people) is a disease that appears as new cases in a given human population, during a given period, at a rate that substantially exceeds what is expected, based on recent experience (the number of new cases in the population during a...

The family Orthomyxoviridae is comprised of Isavirus and Thogotovirus, with three types of influenzavirus: Influenzavirus A, Influenzavirus B or InfluenzavirusC. Although strains A and C are capable of infecting multiple species, B is fairly exclusive to humans.
Influenzavirus B is far less common than Influenzavirus A, and seals are the only other animal known to have carried this strain of influenza B. This strain is less genetically diverse because it mutates 2-3 times slower than type A, resulting in only one influenza B serotype.
InfluenzaC is the least common of the three strains.
