The most known subtype of this virus is the H1N1 virus, which caused the so-called 'Bird flu' and 'swine flu'. Currently, subtypes of H1N2 and H3N2 viruses are also common in humans. Influenza A is particularly dangerous because of the rate of mutation. The immune system is unable to recognize the virus and defend itself effectively. 1. Flu virus A The influenza A virus is very susceptible to mutations. It has 8 independent RNA segments, which allows it to exchange genes with other strains of the virus. One type of virus is usually "specialized" in one type of infection. The protein shell of each type A virus is composed of highly immunogenic glycoproteins: hemagglutinin (HA or H) and neuraminidase (N...
