Sexual Transmission of Zika Virus: What to Know 24 Feb 2016 | Ready Marine Corps PRINT SHARE The Centers for Disease Control is investigating 14 cases of Zika Virus possibly being transmitted by sex, including to pregnant women. Last week, the Marine Corps issued MARADMIN 083/16 that details precautions to take when returning from a Zika Virus affected area. Because of the possibility of sexual or serological transmission, men who could have been exposed to the virus “should consider abstaining from sexual activity or consistently and correctly use condoms during sex for at least 10 weeks.” Men with a pregnant partner should abstain from sex or always use condoms during sex for the duration of the pregnancy. Anyone who has traveled to an affected area should not donate blood for 28 days. The full effects of Zika and its transmission are being investigated closely by the CDC. However, it supports the guidance above as well as interim recommendations for women who are pregnant or trying to become pregnant. Female service members and dependents who are pregnant or trying to become pregnant should consult their doctor before traveling to affected areas. All service members and dependents, especially those who are pregnant, should contact their doctor and report their travel history immediately if they suspect they are infected.
