A wave of fear over Ebola that has prompted schools to close, a university to delay a speech by a West African journalist and flight crew to reportedly panic over a sick passenger could have a damaging impact across the U.S. if it escalates, public-health experts say.
The Department of Homeland Security on Wednesday will begin limiting flights carrying passengers from three West African countries affected by Ebola to arrival at five U.S. airports.
Johnson & Johnson said it would begin testing an Ebola-virus vaccine in humans in January and could have 250,000 doses available in May.
