The September 30, 1862 Richmond Daily Dispatch reported that there had been five deaths from Yellow fever on Friday in Wilmington, but no new cases had been reported up to noon Saturday.
Charleston had sent eight nurses to help and General Beuregard had sent Dr. Choppin, a physician on his staff to help as well.
There is also a 32-page pamphlet available "The Yellow Death: Wilmington and the Yellow Fever Epidemic of 1862" by Jack F. Fryar.
With blockade-runners loading at Caribbean ports, it is not surprising that port cities were prime candidates for these outbreaks.
