Figure 1. Everglades virus–seropositive and -seronegative dogs in Florida, 2003–2004. A total of 633 samples of dog sera from the Veterinary Medical Center in Gainesville or Hollywood Animal Hospital in Miami were screened. Each blue dot (seronegative) or red star (seropositive) represents a single dog. Most of the seropositive dogs lived in north-central Florida, outside the recorded range of the principal vector Culex (Melanoconion) cedecei or previously recorded Everglades virus activity (purple shading). Owners of dogs living outside the endemic region reported that their animal had not traveled to south Florida.
