The Centers for Disease Control and Prevention says it is monitoring 77 people who had contact with patients diagnosed with Ebola. Seventy-six of those, CDC Director Tom Frieden said in a press conference, were health care workers who cared for Eric Duncan, the first person diagnosed with Ebola in the United States. Frieden said Nina Pham, the nurse who contracted Ebola while caring for Duncan, had contact only with one other person before she was isolated. Frieden says because Pham sought treatment quickly, the number of people potentially exposed to the deadly virus was limited. David Lakey, the commissioner of the Texas Department of State Health Services, said that they have not yet identified any error in procedure that could have led to Pham's infection. via NPR.
