Frederick News-Post, Pa., Jan. 3, 2007 It won't be long before the doors to Fort Detrick's huge homeland security laboratory swing open, as evidenced by our collective calendar turning to 2007 and the recent awarding of a management contract to Battelle.  Six BSL-4 laboratories now operate in the United States, including Fort Detrick's USAMRIID, National Institutes of Health in Bethesda, Centers for Disease Control in Atlanta, the Viral Immunology Center at Georgia State University in Atlanta, the Southwest Foundation for Biomedical Research in San Antonio and the University of Texas Medical Branch in Galveston, Texas.
