As the Ebola scare continues, one of Texas' most renowned epidemiologists was tasked with helping efforts to control the outbreak in one country. Dr. Tom Ksiazek, an epidemiologist at UTMB, recently came back from Sierra Leone, which has been hit hard by the Ebola outbreak. He led outbreak containment operations there; something he has done many times as the head of the Special Pathogens unit at the Centers for Disease Control since the mid-1970s. Ksiazek is also the director of the high containment laboratory operations for the Galveston National Laboratory, where some of the world's most dangerous viruses are studied. The news also appeared on KTRK-TV (ABC, Ch. 13) and KPRC-TV (CBS, Ch. 2).
