Ok please, please I'm not trying to be rude, but can we please keep this somewhat non-alarming. There was cases of dengue in Key West @ 2009-2010, it was not an epidemic in the slightest bit. Tourism was not affected, locals didn't flee, nor were they overly concerned.
Sorry to seem passionate about this, but we're talking about a part of the country that I know and love, and what is being talked about here is completely sensationalized.
Let's not try to scare people away from SoFla, the Keys, or even WDW. There are a lot of dangerous things in Florida, even more "danger" in SoFla if you want to get technical. Most people never actually experience any of that danger. Locals or tourists. They certainly don't walk around in fear.
There are plenty of us on this thread
@Kylo Ken just mentioned earlier as well, who don't stop living because of a potential small chance of danger.
