Probable Locally Acquired Mosquito-Transmitted Plasmodium vivax Infection—Georgia, 1996

Abstract

Endemic, mosquitoborne transmission of malaria was interrupted in the United States during the 1940s. Since then, 57 small localized outbreaks of probable mosquito-transmitted malaria in the United States have been reported to CDC. This report summarizes the investigation of a case of Plasmodium vivax infection in a resident of Georgia who had never lived in or visited a malarious area. The results of this investigation suggest that this case probably was acquired through the bite of a locally infected Anopheles sp. mosquito, although a probable source of infection for mosquitoes was not confirmed.
