Anthrax Postal Terrorism

2001 | September 18 – October 31, 2001

Following the September 11 attacks in New York City and Washington D.C., the United States suffered through another national scare.

  • Multiple bioterrorism attacks using B. anthracis (anthrax) spores were sent through the mail, resulting in several deaths and numerous exposures.
  • Following recognition of the first cases of anthrax in Florida in early October 2001, investigators from CDC and the Federal Bureau of Investigation were mobilized to assist investigators from state and local public health and law enforcement agencies.
