Emory Healthcare released a statement today updating the status of patient Amber Vinson, who is being treated for Ebola virus disease.

"Emory University Hospital physicians, in collaboration with the Centers for Disease Control and Prevention, are pleased to report that Amber Vinson is making good progress in her treatment for Ebola virus infection. Tests no longer detect virus in her blood. She remains within Emory's Serious Communicable Diseases Unit for continued supportive care. We do not have a discharge date at this time," the statement says.

Vinson arrived at Emory University Hospital on Wednesday, Oct. 15, after being transported by air ambulance from Dallas, Texas. She is the second of two health care workers infected while caring for a patient at Texas Health Presbyterian Hospital. The CDC and Texas Health Resources specifically requested that Vinson be transferred to Emory Healthcare.

Vinson is being treated in the same isolation unit at Emory University Hospital in which three patients have already been treated. The first two patients were discharged in late August; the third patient was discharged Oct. 19.
