There are four types of influenza virus.
*Influenza A : Influenza A viruses cause seasonal flu epidemics practically every year in the United States. They can infect humans and animals.Influenza A is the only type that can cause a pandemic, which is a global spread of disease. Bird flu and swine flu pandemics both resulted from influenza A viruses. An influenza A virus has two surface proteins: hemagglutinin and neuraminidase. These help doctors with classification.
* Influenza B : Influenza B viruses can also cause seasonal epidemics that typically only affect humans. There are two lineages of influenza B: Victoria and Yamagata. Influenza B viruses mutate more slowly than influenza A viruses.
* Influenza C : Influenza C viruses cause mild illnesses — they do not appear to cause epidemics.
* Influenza D : Influenza D viruses mainly affect cattle and do not seem to infect humans.
