The thing about Zika is that it’s new to the Western Hemisphere this year. It will probably infect a huge proportion of the population in tropical areas of the Americas in the next year or so, and after that the number of cases will drop because many people will have become immune. And when this happens, fewer mosquitoes will be carrying it.
So a case could be made for rethinking your vacation plans and scheduling a trip to Puerto Rico for, say, two years from now, while going somewhere else this year, especially if there are any women who might become pregnant or male sex partners of women who might become pregnant in your group.
