Update: investigation of bioterrorism-related inhalational anthrax--Connecticut, 2001

Since October 3, 2001, CDC and state and local public health authorities have been investigating cases of bioterrorism-related anthrax. As of November 28, a total of 23 cases have been identified; 11 were confirmed as inhalational anthrax, and 12 (seven confirmed and five suspected) were cutaneous. Epidemiologic investigations to identify the source of exposure to Bacillus anthracis continue for a case of inhalational anthrax in a hospital stockroom worker in New York City (NYC) and, most recently, a case of inhalational anthrax in an elderly woman in Connecticut (CT). Antimicrobial prophylaxis is continuing in persons exposed to B. anthracis, and surveillance to detect new cases of bioterrorism-related anthrax is ongoing. This report summarizes the findings of the case investigation in CT.
