Elizabeth Unger

Elizabeth (Beth) R. Unger, MD, PhD, is the Chief of the Chronic Viral Disease Branch (CVDB), Division of High-Consequence Pathogens and Pathology, National Center for Emerging and Zoonotic Infectious Diseases at the Centers for Disease Control and Prevention (CDC), Atlanta, Georgia. chronic fatigue syndrome (CFS) research falls under her department. She has worked at the CDC since 1997 and replaced Dr. William Reeves as Chief of CVDB in 2010. Dr. Unger has done extensive research at the CDC on the human papillomavirus (HPV).

In 2002-2003, Dr Unger was on the team that tested the validity of 1994 CDC case definition of CFS, known as the empirical definition or Fukuda criteria, via the Wichita Clinical Study. The study, according to the CDC, "identifies persons with CFS in a precise manner that can be readily reproduced by both investigators and clinicians." Many researchers continued to use the Fukuda criteria for research.

Chronic Fatigue Syndrome Advisory Committee
Dr. Unger has represented the Centers for Disease Control and Prevention (CDC) on the Chronic Fatigue Syndrome Advisory Committee (CFSAC), for the U.S. Department of Health and Human Services as an Ex Officio Member.

Education
Dr. Unger received an undergraduate degree in chemistry at Lebanon Valley College, Annville, PA and her PhD and MD in the Division of Biologic Sciences at the University of Chicago. Her residency and fellowship was completed at Pennsylvania State University Medical Center.
