in·flu·en·za
(ĭn′flo͞o-ĕn′zə) A contagious disease caused by a virus that is characterized by fever, inflammation of the airways, and muscle pain. It commonly occurs in epidemics, one of which killed 20 million people between 1917 and 1919.
Word History Since ancient times, influenza has periodically swept the world. In just a few years during the early 1900s, 20 million people worldwide died from influenza, which we commonly call the flu. Until recently, people could not tell how this illness could spread so widely. Before people knew that organisms cause disease, they thought the stars influenced the spread of influenza. The name for this illness, in fact, reflects that belief. Influenza comes eventually from the Latin word influentia, meaning "influence of the stars." Today, however, the stars are no longer blamed for the flu. Modern medicine has found that inhaling certain viruses, called influenza viruses, causes the spread of this illness.
