Ashoka Mukpo, the freelance journalist who contracted Ebola while working for NBC News in Liberia, has been declared free of the virus and will leave a medical facility in Nebraska on Wednesday morning, the hospital announced.

Mukpo arrived at Nebraska Medical Center on Oct. 6 from Liberia, where he became infected. A blood test confirmed Tuesday by the Centers for Disease Control and Prevention shows his bloodstream is now free of the virus, according to a statement from the Nebraska Medical Center.

"Recovering from Ebola is a truly humbling feeling,” Mukpo said in the statement. “Too many are not as fortunate and lucky as I've been. I'm very happy to be alive.”

Mukpo also tweeted the news himself.

Mukpo isn't sure how he caught Ebola while documenting the epidemic in Liberia. "I was around a lot of sick people the week before I got sick,” he said in the statement. "I thought I was keeping a good distance and wish I knew exactly what went wrong."

Mukpo received a convalescent serum from blood donated by another American Ebola survivor, Dr. Kent Brantly.

Mukpo has been tweeting about his ordeal, and earlier this week, doctors said he had been steadily improving.

Mukpo was the Nebraska hospital's second Ebola patient; Richard Sacra, an American physicia, left the facility last month after successfully beating the disease that has killed more than 4,500 people this year.

Texas nurse Nina Pham is still being treated for Ebola at the National Institutes of Health in Maryland, where her condition was upgraded from "fair" to "good" on Tuesday. Pham contracted Ebola in Dallas while caring for the Texas index patient, Thomas Eric Duncan. A second Ebola-stricken Texas nurse, Amber Vinson, is currently being treated at Emory University Hospital in Georgia.

Another Ebola patient, who has not been publicly identified, was released from Emory on Monday after being declared virus-free.
