Dr. Tom Frieden says aerial spraying that began Thursday quickly killed adult mosquitoes that pesticides on the ground couldn't reach. Puerto Rico's governor wouldn't authorize naled's use because of environmental concerns, despite widespread Zika infections there. Florida's Department of Health says there's no evidence of mosquitoes transmitting Zika elsewhere in Miami. The head of the U.S. Centers for Disease Control and Prevention says aerial spraying of the insecticide naled is killing many mosquitoes in a Miami neighborhood where the insects apparently transmitted Zika to 15 people. Frieden says Miami's infections were limited to a 500-square-foot area in the Wynwood neighborhood.
