  • Description:
    The Typhus Investigation Project completed its first year of work in September, 1946. Headquarters for this study were established in Thomasville, Georgia, in September 1945, with sub-headquarters in Quitman, Cairo, and Bainbridge. Training of personnel, acquisition of equipment, and collection of field data got under way in October 1945. Methods of collecting data were fairly well standardized by April 1946, and more suitable space was acquired for headquarters. The organization was crystalized into its present form in July 1946. The principal purpose of the study is to provide a scientific measure of the effects of certain county-wide typhus control operations (particularly DDT dusting) upon the prevalence of human and rat murine typhus fever, and also upon rat ectoparasite abundance. Four counties in South Georgia make up the principal study area. While these counties have not yielded the highest typhus incidence in the United States, they seemed to be best suited to such a study since they had not undertaken any type of community typhus or rat control program for several years prior to the beginning of the present project. A special DDT dusting program was set up for Brooks and Thomas Counties, and a rat-poisoning campaign was planned for Decatur County. After a preliminary period of trapping, these control operations were started respectively in April, May, and June 1946. Operations in Grady County, the control county, were limited to human incidence, rat prevalence, and rat ectoparasite abundance studies, which are parallel to studies in the other counties.
