St. Louis Encephalitis Transmission
During the summer season, St. Louis encephalitis virus is maintained in a mosquito-bird-mosquito cycle, with periodic amplification by peridomestic birds and Culex species mosquitoes. In Florida, the principal vector is Culex nigripalpus, in the Midwest, Culex pipiens and Culex quinquefasciatus and in the western United States, Culex tarsalis and members of the Culex pipiens complex.
