The death toll from a yellow fever epidemic in Philadelphia hits 100 on this day in 1793. By the time it ended, 5,000 people were dead. Yellow fever, or American plague as it was known at the time, is a viral disease that begins with fever and muscle pain.
The evolutionary origins of yellow fever most likely lie in Africa, with transmission of the disease from non-human primates to humans. The virus is thought to have originated in East or Central Africa and spread from there to West Africa.
