Several of our friends got this in Bequia. It is spreading rapidly and is now as far south as Union Island and, I believe, north as far as Florida. Similar to Dengue, very unpleasant, ladies seem to have relapses for much longer than men.

Just came across this. It will be of interest to anyone in or going to the Caribbean:
