"The Laughing Epidemic – The school where laughter became a disease" investigates the bizarre events of 1962 in Tanganyika (now Tanzania). It started with three girls in a mission boarding school giggling. Within days, the laughter spread like a virus. It wasn't happy laughter; it was manic, painful, and accompanied by fainting, crying, and rashes. The school had to be closed. Author Sarah Joyless explains the diagnosis: Mass Psychogenic Illness. The epidemic wasn't caused by a bug, but by the immense stress of a society in transition post-independence. The laughter was a subconscious rebellion against the strict rules of the British-run school system. "The Laughing Epidemic" is a case study in how the body expresses what the mouth cannot say. It shows that emotions can be contagious in the most literal sense, shutting down institutions and spreading across villages like a plague.
