Florida is now entering a more aggressive stage to try to cope with the Zika virus. They will conduct an aerial insecticide spraying campaign at dawn on Wednesday in an effort to kill mosquitoes carrying the Zika virus, officials in Miami-Dade County said. The campaign will cover a 10-mile area that includes the one-mile-square area just north of downtown Miami that health officials have identified as the hub of Zika transmission in the state, the officials said on Tuesday.

On Monday, the U.S. Centers for Disease Control and Prevention issued an unprecedented travel warning, urging pregnant women to avoid travel to the Miami neighborhood at the center of the investigation. The Zika outbreak was first detected last year in Brazil, where it has been linked to more than 1,700 cases of microcephaly, a birth defect marked by small head size that can lead to severe developmental problems in babies.
