MIAMI – An investigative summary released by the U.S. Centers for Disease Control says the Zika outbreak in Miami's Wynwood arts district was centered on three businesses with outdoor areas shared by employees, customers and breeding mosquitoes. It also says the number of people infected was likely greater than reported.
The outbreak -- the first for the U.S. mainland -- lingered for more than a month but was limited to a small geographic area, much like previous outbreaks of mosquito-borne viruses in Florida.

Just over two weeks after aerial spraying of pesticides began Wynwood, no further infections with Zika were reported in the neighborhood.
While health officials stressed their campaign against the mosquitoes carrying the virus included ground-based spraying and turning over stagnant water, they said the aerial spraying appeared a key in halting the infections.
