Obama: US can't cut itself off from West Africa

President Barack Obama urged Americans on Saturday not to succumb to hysteria about Ebola, even as he warned that addressing the deadly virus would require citizens, government leaders and the media to all pitch in.

In his weekly radio and Internet address, Obama also pushed back against calls for the U.S. to institute a travel ban. Lawmakers have called it a common-sense step to prevent more people with Ebola from entering the U.S., but Obama said such a ban would only hamper aid efforts and screening measures.
