1878 Mississippi Valley Outbreak
- When
- 1878 (started by March)
- Where
- Lower Mississippi Valley
A severe yellow fever epidemic swept through the lower Mississippi Valley in 1878; Memphis recorded more than 5,000 deaths in its official register.
The outbreak had started by March 1878 and was thought to be connected to an ongoing yellow fever outbreak in Havana. It was the worst epidemic that occurred in the state of Mississippi. In Memphis, the epidemic's principal focus, more than 5,000 people were listed in the official register of deaths between July 26 and November 27, 1878; that register window reflects the Memphis death toll rather than the epidemic's overall end.
