— “Zika can be passed through sex from a person who has Zika to his or her
sex partners. Sex includes vaginal, anal, oral sex, and the sharing of sex toys.
Zika can remain in semen longer than in other body fluids, including
vaginal fluids, urine, and blood.”

— “Because most people infected with the Zika virus don’t show any symptoms, blood donors in transfusions may not know they have been infected and can transmit Zika virus.”
