CDC is working with other public health officials to monitor for ongoing Zika virus‎ transmission. Tuesday, CDC posted a Zika virus travel notice for The Bahamas. Local transmission of Zika has been reported on the island of New Providence, which includes the capital city of Nassau. CDC has issued travel notices (level 2, “practice enhanced precautions”) for people traveling to destinations with Zika.

As more information becomes available, CDC’s travel notices will be updated. Travelers to areas with cases of Zika virus infection are at risk of being infected with the Zika virus. Mosquitoes that spread Zika are aggressive daytime biters. They also bite at night. There is no vaccine or medicine for Zika virus. The best way to avoid Zika virus infection is to prevent mosquito bites. 

Some travelers to areas with Zika will become infected while traveling but will not become sick until they return home and they might not have any symptoms. To help stop the spread of Zika, travelers should use insect repellent for three weeks after travel to prevent mosquito bites.

Some people who are infected do not have any symptoms. People who do have symptoms have reported fever, rash, joint pain, and red eyes. The sickness is usually mild with symptoms that last from several days to a week. Severe disease requiring hospitalization is uncommon and the number of deaths is low. Travelers to areas with Zika should monitor for symptoms or sickness upon return. If they become sick, they should tell their healthcare professional when and where they have traveled.

CDC has received reports of Zika virus being spread by sexual contact with sick returning travelers. Until more is known, CDC continues to recommend that pregnant women and women trying to become pregnant take the following precautions.
