Of course, the risks are greater for pregnant women, and those who may become pregnant, and those people do need to take extra precautions and be more careful than they may possibly be otherwise.
However, it is important to remember that, while the symptoms and effects of Zika on the general population are perceived to be minimal, there are risks, you may get mild flu like symptoms (which may not, in themselves, be hugely problematic), but, it does reduce your immunity SIGNIFICANTLY, so, even though you don't feel too ill, it could be a really big deal if you are a person who is already unknowingly living with immunosuppression.
So, it is, perhaps useful to consider your health with relation to Zika even if you are not a pregnant / possibly pregnant woman.
(to add, this information was presented to my husband, who has chronic leukaemia, by his doctor. We ARE travelling to florida, in winter, and he WILL be taking additional precautions, using DEET etc, but he KNOWS he is immunocompromised, so he knows to do this)
