The World Health Organization has now classified Ebola as an international health emergency.
WHO leaders say the disease is spreading in nations not equipped to deal with it, and they're calling for international solidarity to help stop it.
That has international travelers on high alert. WGN's Judy Wang reports travelers she spoke with at O'Hare International Airport aren't taking any drastic actions. All of them are continuing with their plans but are doing so with a bit more awareness.
Experts says that's about all travelers can do at this point. They advise people to be aware of where other passengers are traveling from and limit exposure to anyone who has been to western Africa.
Ebola is passed along by contact with bodily fluids.
