MIAMI BEACH, Fla. – The director of the U.S. Centers for Disease Control and Prevention says officials will not be able to spray the South Beach area to prevent Zika as they have in other areas because of high-rise buildings and strong winds.

Miami-Dade County officials have been spraying pesticide from planes flying over Miami's Wynwood arts district since early this month, when Zika transmissions by mosquitoes were confirmed there.

Dr. Tom Frieden says planes can't fly low enough among Miami Beach's high-rises to spray pesticides that kill mosquitoes and their larvae. He says strong winds over the narrow island city also hinder such flights.

Frieden also says the large numbers of residents and visitors in the area will make it challenging to control the spread of Zika there.

Florida officials announced on Friday that they had identified South Beach as a second area of Zika transmission on the U.S. mainland.
