US Health Officials Respond to New Ebola Case

America’s top disease control official says the first known transmission of Ebola in the United States dictates a rethinking and a redoubling of protocols to protect health care workers and the public from the deadly virus. A nurse in Dallas, Texas has tested positive for Ebola after caring for Liberian Thomas Eric Duncan, who died last week. VOA's Michael Bowman reports, the new case prompted President Barack Obama to adjust his schedule to get an update on Ebola-containment efforts.
