What we don’t know about Zika
- If there is a safe time during pregnancy to travel to an area with Zika.
- If you are pregnant and infected, how likely it is that the virus will infect your fetus and if your baby will have birth defects.
While Brazil and Central America have been reporting the vast majority of cases, Zika has been affecting people around the world. As summer commences in the western hemisphere, there is a great concern the Aedes species mosquito, which carries the virus, will further migrate north.
Centers for Disease Control and Prevention (CDC) has issued a travel notice for people traveling to areas where Zika virus is spreading. For a current list of places with Zika outbreaks, see CDC’s Travel Health Notices:
Microcephaly is a condition where a baby’s head is much smaller than expected. Microcephaly can occur when a baby’s brain has not developed properly during pregnancy, or has stopped growing after birth, which results in a smaller head size.
Microcephaly has been linked with the following problems:
- Developmental delay, such as problems with speech or other developmental milestones (like sitting, standing, and walking)
- Intellectual disability (decreased ability to learn and function in daily life)
- Problems with movement and balance
- Feeding problems, such as difficulty swallowing
- Hearing loss
- Vision problems
These problems can range from mild to severe and are often lifelong. Severe microcephaly can also be life-threatening.
