United Airlines says customers booked to fly to areas affected by the Zika virus can reschedule or get refunds.

American Airlines says it will give refunds to pregnant women who were planning to travel to parts of Central America.

The U.S. Centers for Disease Control and Prevention have warned pregnant women to take precautions against mosquito bites when traveling to areas in Latin America and the Caribbean where there have been Zika outbreaks. The CDC says the mosquito-borne illness could be linked to a birth defect of the brain.

The United Airlines offer began Tuesday and includes any country covered by a CDC travel notice. American Airlines began refunds Monday for pregnant passengers holding tickets to El Salvador, Honduras, Panama or Guatemala.
