Most of the Zika infections from Florida mosquitoes have been in the Miami area, not the tourist mecca of Orlando and its Walt Disney World, Universal and SeaWorld theme parks.



But Miami is a major tourism draw, with more than 15.5 million people making overnight visits to the city and its nearby beaches last year. Florida in general has a lot to lose as Zika spreads: The state set a new record for tourism with more than 105 million people from out of state and other countries visiting in 2015.



Officials said they are not considering asking restaurants and bars in the area to temporarily close outdoor dining areas, but they will increase spraying, trapping and testing.



"This is a very, very difficult mosquito to control," said Gimenez. "The CDC director once told me this is the cockroach of mosquitoes, that it will find a way somehow to breed."



Since July, authorities have linked a couple dozen Zika cases to transmission in small areas of Miami's Wynwood district and the popular South Beach neighborhood of Miami Beach. Other isolated cases not linked to travel outside the U.S. also have been confirmed elsewhere in Miami-Dade county, as well as in neighboring counties and in the Tampa Bay area, totaling 49 for the state.



A third of people surveyed in the poll believe Congress should make approving more funds to combat Zika a top priority. President Barack Obama proposed $1.9 billion in emergency funding for Zika in February, but Congress has been unable to agree on a final bill.



The poll of 1,211 adults conducted Aug. 18-24 has a margin of error of plus or minus 3 percentage points.



Scott, a Republican, has repeatedly called on Congress to send the president a Zika funding bill, saying "we still need the federal government to show up."
