Blame the Stars: How 'Influenza' Got Its Surprisingly Cosmic Name

Blame the Stars

The next time you call in sick, you're accidentally speaking medieval Italian astrology. No, really.

The Word

Influenza (een-floo-EN-tsah) — flu, epidemic, influence.

You already know this word. It's sitting right there in English: influenza. But do you know what it actually means in Italian?

Influence.

Origin Story

In medieval Italy, people noticed that flu-like illnesses swept through entire cities at once — everyone got sick at the same time, as if some invisible force had touched them all. They couldn't explain it, so they looked up.

The stars.

Italian physicians and scholars coined the phrase influenza di stelle — "influence of the stars." They genuinely believed celestial bodies were raining disease down on humanity. The planets were misaligned. The cosmos was sick. And so were you.

By the 1700s, the word had been clipped to just influenza, and it spread across Europe as fast as the illness itself. English picked it up wholesale. Every doctor's note, every vaccine insert, every sick day — all carrying a 700-year-old astrological theory.

Fun Fact

The 1743 Italian epidemic was so dramatic it got its own pamphlet blaming Jupiter and Saturn for the outbreak. The word jumped into English newspapers within weeks — making it one of the fastest linguistic imports of the 18th century, spread almost like a virus.
