Flu is classified according to the type of virus that caused the condition. The three main types of flu are Type A, Type B and Type C. The symptoms for all flu types are generally the same, according to About.com. However, Type C flu has less severe manifestations compared to the other two types. WebMD.com says that most of the flu cases that affect the population annually are Types A and B. Unlike Type A flu, Type B flu does not cause pandemics, but it can still be detrimental enough to trigger seasonal outbreaks. Moreover, Type B flu occurs only in human hosts. WebMD.com further reports that immune resistance to all flu types can be obtained by having a vaccine every year, because flu viruses, specifically those classified under Type A, can constantly mutate, therefore becoming invulnerable to the old vaccines that were designed to defend against old virus strains.
