The CDC warns pregnant women against travel to 14 Western Hemisphere countries and territories: Brazil, Colombia, El Salvador, French Guiana, Guatemala, Haiti, Honduras, Martinique, Mexico, Panama, Paraguay, Suriname, Venezuela, and the Commonwealth of Puerto Rico. Women considering becoming pregnant are advised to consult doctors before traveling to countries with Zika cases, and all travelers are urged to avoid mosquito bites, as are residents of Puerto Rico and the United States Virgin Islands. CDC:
We believe this is a fairly serious problem. This virus is spreading throughout the Americas. We didn’t feel we could wait. [The advisory applies to the entire countries] unless there is specific evidence the virus is not occurring somewhere.
