Why are there specific recommendations for pregnant women?

There may be a link between a serious birth defect called microcephaly—a condition in which a baby's head is smaller than expected—and other poor pregnancy outcomes and a Zika infection in a mother during pregnancy. While the link between Zika and these outcomes is being investigated the CDC recommends that you take special precautions if you fall into one of these groups:

  • If you are pregnant (in any trimester):
  • You should consider postponing travel to any area where the Zika virus is active.
  • If you must travel to an active region, talk to your doctor first and follow the steps to prevent mosquito bites during your trip.
  • If you are trying to become pregnant:
  • Before you travel, talk to your doctor about your plans to become pregnant and the risks posed from infection.

If you fall into one of these groups,the CDC has provided thorough information on what you should do.
