Blood samples from a patient at a Northern California hospital, who is suspected of having been exposed to the deadly Ebola virus, will be tested by the federal Centers for Disease Control and Prevention, officials said.
There have been no confirmed cases of Ebola in the United States, though two American relief workers who contracted the disease in Liberia were flown back to America for treatment earlier this month.
Since a recent outbreak of the disease in West Africa that has killed more than 1,200 people, several people suspected of exposure have been examined in the United States.
