News:Dallas Nurse Amber Vinsion Ebola-free discharged from Hospital

(CNN) -- 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.
