Medical Countermeasures

Following the 2001 anthrax attacks, the federal government requested that all health departments in the United States develop plans to rapidly and safely provide medication to the public in the event of a public health emergency. The primary goal of such plans is to save lives and prevent illness. Medicines such as pills or vaccines that can prevent the onset of illness are called medical countermeasures (MCM). The process of providing MCM to many people during a short period of time is called mass prophylaxis. During a health emergency, medications may be dispensed to people at locations called Points of Dispensing, or PODs.

Contra Costa Health Services uses the following tool to determine the best medicine for people exposed to anthrax during a bioterrorism incident.
