The word influenza comes from the Italian word 'influentia.' Centuries ago, people believed unfavorable astrological influences caused the flu. Influenza is passed on by microbes from coughs and sneezes. When somebody expectorates, droplets spray onto a nearby surface, or onto other people. Coughing or sneezing directly into your hands means your hands then carry droplets to the surfaces they touch. Type A Influenza spreads quickly. It is capable of mutating, infecting, devastating a diverse population of species.
