Zika virus continues to be a concern.  There is now a strong suspicion that Zika can be spread through semen.  CDC has received reports of sexual transmission of Zika virus among women whose only risk factor was sexual contact with a male partner with recent travel to Zika areas.  The CDC recommends that pregnant women refrain from traveling to Zika areas and couples planning on becoming pregnant should speak with their health care providers before traveling to countries where Zika virus has been identified.  If travel to these countries is necessary, then precautions to prevent mosquito bites should be implemented.

What are the implications for public health practice?  (CDC recommendations)

Men who reside in or have traveled to an area of ongoing Zika virus transmission who have a pregnant partner should abstain from sexual activity or consistently and correctly use condoms during sex (i.e., vaginal intercourse, anal intercourse, or fellatio) with their pregnant partner for the duration of the pregnancy.
