Trying to control the mosquitoes to curb infections has not proven to be all that effective, he said. People who have air conditioning or screened windows may be at lower risk, since a closed house keeps the flying insects at bay.
Infectious disease expert Dr. Marc Siegel, an associate professor of medicine at New York University in New York City, agreed with the experts' warnings. "I wouldn't be surprised to see more cases," he said.
The problem is that the mosquitoes in Key West are now carrying the disease, which makes it more likely that there will be more outbreaks, Siegel said.
