Zika

Looking at where it is showing as hot zones in the US, particularly in South Beach in Miami, anywhere that moskitoes are present can be a risk for Zika at the moment. It is definitively NOT only in areas where poor people are concentrated. If heavy fogging is not happening and you have an active mosquito population, you are at risk and it is a concern if you are thinking at getting pregnant or currently pregnant and possibly people with compromise immune system.

Nope, it's probably still ramping up:
The Zika virus was first identified in 1947, in a forest in Uganda, from which it got its name. Outbreaks have occurred in the Pacific Islands, Yap in particular.
This current outbreak appears to be by far the most widespread to date and shows no signs of fading presently. In fact the mosquito that carries the Zika virus has an extensive range and is showing some signs of resistance to insecticides https://www.sciencedaily.com/releases/2016/08/160817171732.htm Here's a brief snippet:"But Aedes aegypti appear to quickly develop insecticide resistance. In laboratory and field research, Cornel is studying Aedes aegypti's uncanny ability to survive certain insecticide treatments."
