The Laughing Plague That Took Over a Town

In 1962, a laughter epidemic swept through a Tanzanian village, starting with a few schoolgirls and spreading uncontrollably.

What began as giggles escalated into months of mass hysteria, affecting hundreds. Scientists now believe it was a case of mass psychogenic illness—where stress triggers contagious, involuntary reactions.

This bizarre event proves that emotions, even laughter, can be as infectious as any virus.
