[Q]: A nurse's release Tuesday from an Atlanta hospital leaves a single person in the United States now battling Ebola, though she and others -- including President Barack Obama -- stressed the fight against the deadly virus isn't over. "While this is a day for celebration and gratitude, I ask that we not lose focus on the thousands of families who continue to labor under the burden of this disease in West Africa," said 29-year-old Amber Vinson. About two weeks ago, Vinson became the second nurse from Texas Health Presbyterian Hospital Dallas to get the virus while caring for Thomas Eric Duncan, a Liberian man who began showing Ebola symptoms after arriving in Texas and died of it there. She and Nina Pham -- the other Dallas nurse who was discharged from a National Institutes of Health facility in Maryland on Friday -- are differ from the handful of other U.S. Ebola cases in the United States because they caught the disease in America, rather than contracting it in West Africa.Discharged nurse asks that we don't "lose focus" on those suffering in West AfricaU.S. cannot "react based on our fears," President Obama saysU.S. diplomat arrives in Liberia to show "solidarity"There's now only one person, a doctor in New York, with Ebola in the United States
