Type A influenza is the most common type that causes seasonal outbreaks. It occurs in both people and animals and can be spread by people who are already infected touching items, from being close to someone who is infected and through sneezes or coughs. Influenza A is further separated into sub-sets, including strains N and H, and there are even subsets of those strains!
It is another virus that is responsible for many outbreaks worldwide yearly. It only appears in humans and can be very dangerous, although technically not as severe as Type A. It does not cause a pandemic, and while there are different strains of the virus, it is not broken down into different subtypes.
It is the only other human virus that is less severe than type A and B. Patients may complain of mild respiratory problems. Type C does not cause pandemics and symptoms are close to those of a cold.
