It commonly occurs in epidemics, one of which killed 20 million people between 1917 and 1919. Word HistorySince ancient times, influenza has periodically swept the world. Until recently, people could not tell how this illness, which we call the flu, could spread so widely. Before people knew that organisms cause disease, they thought the stars influenced the spread of influenza. Influenza comes ultimately from the Latin word influentia, meaning influence of the stars. Today, however, the stars are no longer blamed for the flu. Inhaling influenza viruses causes the spread of the illness. The American Heritage® Science Dictionary Copyright © 2011.
