"Since the September 11 attacks, the Agency for Toxic Substances and Disease Registry (ATSDR) has worked with other federal agencies, state and local health departments, and other organizations to respond to the enormous challenges of this tragedy. ATSDR also assisted in the response to the anthrax contamination of postal facilities, government, and media offices. ATSDR, an agency of the U.S. Department of Health and Human Services, worked in partnership with the Centers for Disease Control and Prevention (CDC) in many of these activities and provided workers to help staff the CDCs emergency operations center, which operated around the clock. Altogether, more than 120 ATSDR staff members have been directly involved in the response effort."
