CDC Updates Zika Prevention and Pre-Pregnancy Guidance

The Centers for Disease Control and Prevention updated its interim guidance, extending the recommended wait time and condom use for asymptomatic men with potential Zika virus exposure before attempting conception with their partners, based on ongoing assessment of available data.

In Plain English: The Clinical Takeaway

• Extended Waiting Periods: Asymptomatic men with potential Zika exposure must now wait longer before attempting pregnancy with their partners.
• Prolonged Barrier Protection: Extended condom use is recommended for these male partners to protect against sexual transmission of Zika virus infection.
• Evidence-Based Revision: These adjustments stem from continuous public health assessments of available data.
