On Tuesday, United Airlines announced customers with tickets for areas currently affected by the Zika outbreak can get a full refund, Reuters reports. The offer is good for any areas currently listed by the Centers for Disease Control and Prevention. According to USA Today, that covers 20 countries and territories in South America and Central America at the moment. American Airlines is also offering refunds, though only for locations in Honduras, Panama, and Guatemala, and travelers need a doctor's note citing pregnancy. Zika is mostly spread by mosquitoes, and experts believe it will make its way to most of the Americas.
