Influenza B almost exclusively infects humans and is less common than influenza A. Flu type B also mutates about two to three times more slowly than influenza A. Because humans are the natural host of influenza B, pandemics generally do not occur with influenza B viruses.22 Although scientists...

Researchers divide flu viruses into three general categories: types A, B, and C. All three types can mutate, or change into new strains, and type A influenza mutates often, yielding new strains of the virus every few years. This means that you can never develop a permanent immunity to in...

Type C infection usually causes either a very mild respiratory illness or no symptoms at all. It does not cause epidemics and does not have the severe public health impact of influenza types A and B. Efforts to control the impact of influenza are aimed at types A and B, and the ...
There are two main types of influenza viruses that affect people:Type A and Type B. Both types are behind the influenza epidemic that hits the United States each year.Millions of people in the U.S. are impacted by the flu annually, with the elderly, infants, and those with chronic diseas...
What’s the difference between Type A and Type B? Influenza A viruses come in many varieties. Four subtypes commonly affect humans. But many more influenza A viruses have been identified in animals, which makes it a potential source of pandemics whenever a new type of influenza A jumps to ...
Influenza B viruses aren't divided into subtypes; instead, they are classified into two lineages: B/Yamagata and B/Victoria. While there are many types of flu, it is important to note that the "stomach flu" isn't a type of influenza. Rather, it is gastroenteritis, an inflammation of ...
Influenza in humans is primarily caused bytype Aand B virusesof the Orthomyxoviridae family. The influenza virus is a single-stranded RNA that has 3 membrane proteins that help the virus enter into human cells, replicate and disperse to infect other cells: ...
