Texas Health Presbyterian Hospital released a video of Dallas Ebola patient Nina Pham joking around with her doctors Thursday night, shortly before she was transported to a Maryland hospital.

Pham was diagnosed with Ebola Friday, making her the first person to contract the virus in the U.S. A second nurse, who also treated Ebola patient Thomas Eric Duncan, tested positive for the virus a few days later.

According to the hospital, Pham's physician and coworker, Dr. Gary Weinstein, made the video and shared it at Pham's request. She was flown from the Dallas hospital to a National Institutes of Health hospital in Bethesda, MD Thursday.

She was given a plasma transfusion Monday from Ebola survivor Dr. Kent Brantly, who also donated blood to NBC cameraman Ashoka Mukpo and Dr. Rick Sacra. All three patients are reportedly doing well.
