— -- Former Ebola patient Dr. Rick Sacra has been released from his second hospitalization since returning to the United States from Liberia, according to UMass Memorial Medical Center, where he was diagnosed with and treated for an upper respiratory infection over the weekend.
Sacra was admitted to the Worcester, Massachusetts, hospital on Saturday, a little more than a week after he was discharged from the Nebraska Medical Center, where he was being treated for Ebola.
UMass Memorial officials said they did not believe that Sacra had relapsed, but isolated him and tested him again for the deadline virus. They confirmed Sunday night that his tests came back negative.
Sacra was the third of four American health workers who have been brought to the U.S. after being infected with Ebola, since the outbreak started in West Africa in March.
