Dare County Health Department requested help identifying the source from the state Bureau of Epidemiology. The investigators quickly performed descriptive epidemiology. The epidemic curve indicated a point source epidemic, and most of the cases lived in the Outer Banks area, although some lived as far away as Plymouth.
