Zika virus is primarily transmitted through the bite of infected Aedes mosquitoes. It can also be transmitted from a pregnant mother to her baby during pregnancy or around the time of birth. The Centers for Disease Control and Prevention (CDC) in the US has issued a travel advisory for people travelling to regions and certain countries where Zika virus transmission is ongoing, including Brazil, Colombia, El Salvador, French Guiana, Guatemala, Haiti, Honduras, Martinique, Mexico, Panama, Paraguay, Puerto Rico, Suriname, and Venezuela.
At this time, the CDC recommends special precautions for pregnant women and women trying to become pregnant:
- Pregnant women should consider postponing travel to the areas where Zika virus transmission is ongoing. Pregnant women who travel to these areas should consult with their healthcare provider first, and follow steps to prevent mosquito bites during the trip.
- Women trying to become pregnant should consult with their healthcare provider before travelling to these areas, and follow steps to prevent mosquito bites during the trip.
