Though Wynwood has Zika cases reported, the source may be PortMiami and the islands between the port and Wynwood. The malaria problem was halted by spraying a fine mist of oil, which broke the surface tension on standing water and drowned mosquito larvae.
I suggest that a perimeter around the port, airport and a line from the port to Wynwood across the bay will arrest the problem.
Considering vectors such as entry points and wind patterns would better arrest the problem.
