What Really Happened?
January 30th, 1962
A group of girls started laughing in class for unknown reasons
Affected about 100 students, ranging from 12 - 18 year olds
The humorless laughter spread around the school
Forced shut down - March 18th - May 21st.

Nshamba
Bukoba
The Kashasha Girls' Boarding School closed down again in June
By this time, the epidemic has spread in many other villages.
Mostly affected schools
Parents of the students were also affected
Symptoms
The laughing had nothing to do with humor; it was one of many symptoms
Other Symptoms
– Anxiety from pain
– Fainting
– Respiratory problems
– Crying attacks
– Rashes
Possible Causes
No specific cause, but there are theories:
Caterpillar Plague
Girls might have stepped on them
Stress caused by new independence from Britain
Feeling of inferiority - lack of power due to 40 years of British rule
independence obtained a few weeks before epidemic
Protestant/Catholic missionaries
Feeling of inferiority
Due to teachers and parents' high expectations from students (#troylife)
Laughing Facts
