Is you wife pregnant? Or planning to get pregnant while at Desire or in the 2-3 months after your visit?
If you answered no - then what's the worry? Zika is one of those things that most people who get it - think they have a mild case of food poisoning and within 2-3 days most symptoms have passed and in a week it's gone... and the great thing is... once exposed you'll never get it again.
Both of us have had it (South East Asia 15 years ago) so we aren't worried about it at all.
Do some reading on the CDC website:
