Interim guidance for prevention of sexual transmission of Zika Virus – United States, 2016 update
The CDC interim guidance concerns the prevention of sexual transmission of Zika virus. Zika can be sexually transmitted from a man to his sexual partner, and it is of particular concern during pregnancy. The guidance applies to men who have travelled to or reside in areas with active Zika virus transmission and their sex partners. Potential sexual exposure is defined as any person who has had unprotected sex with a man who has travelled to or resides in such areas. The guidance, updated in April 2016, includes time intervals, after travel to areas with active Zika virus transmission or after Zika virus infection, for taking precautions to reduce the risk for sexual transmission. It will be updated as more information becomes available.
