Originally the Italian word influenza
meant what the similar-sounding word in English, influence,
means: "the act or power of producing an effect indirectly." But it also had the Latin meaning of "an invisible fluid through which the stars and planets control and direct the earth and things and people on it." When epidemics raged through Europe, no one knew what the real cause was. People blamed them on evil stars working through the invisible fluid, or influence. For this reason the Italians called the disease influenza.
In 1743 an epidemic very much like our modern flu began in Rome and spread. That was when the Italian word was borrowed into English. Flu
is a shortened form of influenza.
