Another Texas doctor plans to follow Dr. Kent Brantly to West Africa.
Dr. Thomas Ksiazek is a professor at the University of Texas at Galveston. He plans to fly to Sierra Leone in one week. Once he's there, he will work to track Ebola patients or anyone who has been in close contact with the virus.
Dr. Ksiazek says he's not worried and is prepared for the challenge.
He and his colleagues at UT Galveston are working on a possible vaccine for Ebola. They say it has proven successful in lab tests.
