According to WHO, out of all influenza virus types, influenza A and influenza B viruses cause seasonal epidemics. influenza A virus is mainly responsible for seasonal flu, according to a 2007 study, there have been 3 influenza subtypes- H1N1, H1N2 and H3N2 infected people throughout the world. H1N1 which is an orthomyxovirus containing glycoproteins hemagglutinin and neuraminidase led to major outbreaks like the 1918 Spanish flu pandemic and 1977 Russian flu pandemic and the 2009 swine flu pandemic. H1N2 also from the orthomyxovirus family is found in pig populations and rarely seen in humans and this virus is also known as the bird flu virus. H3N2 also from the family of Orthomyxovirus can infect birds, and mammals, H3N2 derives its name from 2 surface proteins these are hemagglutinin (H) and Neuraminidase (N). H3N2 undergoes antigenic shift which protects it from immune response.
