Counseling Pregnant Women

  • A pregnant woman can pass Zika virus to her fetus during pregnancy (congenital transmission) or at/around the time of delivery (perinatal transmission). Zika virus infection during pregnancy can cause congenital microcephaly & other severe brain defects. Infection at any point during pregnancy may pose a risk to the fetus.
  • Pregnant women should be encouraged not to travel to areas with active Zika Virus transmission.
  • Currently, there is no evidence suggesting past Zika virus infection poses increased risk of birth defects for subsequent pregnancies once the virus has completely cleared a woman’s body.
  • Transmission of Zika virus infection through breastfeeding has not been documented, although Zika virus has been detected in breast milk. Given the benefits of breastfeeding, mothers are encouraged to breastfeed even in areas with Zika.
