Goodness! That is much more concerning than what the information I have been presented with has portrayed. My field is in obstetrics and so obviously the bulk of what I have read has centered primarily on the hazardous effects in pregnancy.
That said, if the Zika virus is potentially responsible for mental health impairments in otherwise previously healthy adults... Maybe... Just maybe it would be in the publics best interest to initiate an avoid non-essential travel advisory to affected destinations, including Florida, as currently only pregnant women or those planning to become pregnant are being warned against travel. At least until more information becomes known about the virus.
Bug spray is great in that it does greatly reduce the likelihood of getting stung, but it doesn't come close to eliminating that risk. I've used bug spray on numerous occasions and never once have I avoided being bitten altogether. It's greatly reduced the number of bites I've received, but they still get me none-the-less.
I love Disney, but I must admit, I'm a little more concerned now about our next scheduled trip than I was previously :/
