Obama: 'Trying to Seal Off' West Africa Could Make Ebola Woes Worse

"This is a serious disease, but we can't given in to hysteria or fear."

President Barack Obama on Saturday urged Americans to avoid hysteria over Ebola, and played down the idea of travel bans from Ebola-ravaged countries in West Africa, explaining that restrictions could make things worse.

Lawmakers this week urged Obama to bar people from Liberia, Sierra Leone and Guinea from entering the United States. Obama has said he is not philosophically opposed to travel bans, but in his weekly address made it clear that he is not leaning toward them.
