Nina Pham, the first Texas nurse infected with Ebola, can be seen speaking in a video released by Texas Health Presbyterian Hospital Dallas before her transfer to an isolation unit at the National Institutes of Health in Bethesda, Maryland.

In the video, Pham jokes with her treating physician Dr. Gary Weinstein, "Come to Maryland, everyone."

While the specifics of her condition are not known, Pham appears alert and upbeat. She cries, telling her attending treatment team "I love you guys."

Weinstein says, "Thanks for being a part of the volunteer team to take care of our first patient," referring to Pham taking part in the treatment of a Liberian man infected with Ebola who later died .

Pham was admitted later on Thursday to the NIH Clinical Center's Special Clinical Studies Unit to be treated by infectious disease and critical care experts . She is the first known Ebola case to be handled in Maryland.

Amber Vinson, the other nurse infected with Ebola after treating the Liberian patient, was sent on Wednesday night to Atlanta's Emory University Hospital , which has handled other Ebola cases from U.S. patients returning from West Africa.
