Authorities in Florida went into damage-control mode when Zika-carrying mosquitoes began biting in the Miami area this summer, fearing the economy would suffer as pregnant women were warned to avoid the Wynwood art district and touristy South Beach.

Containing Zika here will take finesse, advocates say. Mosquito control inspectors are making thousands of house calls, trucks are spraying pesticides before dawn and tropical plants that trap water where mosquitoes breed will be pulled from city-owned spaces.

But no aerial spraying is planned, and community organizers are concerned that poor women won't get the help they need.
