Obama Considers Ebola Czar; Texas Toughens Monitoring

WASHINGTON (AP) — President Barack Obama is conceding that it may make sense to have a single person lead the administration's effort to fight Ebola. But he says imposing a travel ban from disease-ravaged West Africa, as Republicans have demanded, would be counterproductive.

In Dallas, the epicenter of Ebola in U.S., officials took a tougher approach toward monitoring dozens of health care workers who were exposed to the virus while treating an infected patient who later died.

The health care workers were asked to sign legally binding documents agreeing not to go to public places or use public transportation. Those who break the agreement could face undisclosed sanctions.

The move comes after two nurses who had treated Thomas Eric Duncan at Texas Health Presbyterian Hospital were diagnosed with Ebola.
