The economic impact of a bioterrorist attack: are prevention and postattack intervention programs justifiable?

Area of Science:

• Public Health
• Biosecurity
• Epidemiology

Background:

• Bioterrorist attacks pose significant public health and economic threats.
• Effective preparedness requires understanding and quantifying the potential impact of biological warfare agents.
• Classic agents like Bacillus anthracis, Brucella melitensis, and Francisella tularensis are of particular concern.

Purpose of the Study:

• To model and compare the economic impact of aerosolized Bacillus anthracis, Brucella melitensis, and Francisella tularensis releases in a major city suburb.
• To identify key factors influencing the economic consequences of bioterrorism.
• To provide economic justification for public health preparedness measures.

Main Methods:

• Development of a comparative economic impact model for bioterrorism scenarios.
• Simulation of aerosolized releases of three specific biologic warfare agents.
• Analysis of economic losses based on estimated exposure and disease scenarios.

Main Results:

• Economic impact varied significantly by agent, ranging from $477.7 million (brucellosis) to $26.2 billion (anthrax) per 100,000 persons exposed.
• The model demonstrated substantial economic losses associated with bioterrorist attacks.
• Rapid post-attack prophylaxis was identified as the most critical factor in mitigating economic losses.

Conclusions:

• Bioterrorism preparedness is essential to mitigate severe economic consequences.
• Economic modeling provides a framework for justifying investments in public health security.
• Timely implementation of medical countermeasures, such as prophylaxis, is paramount in reducing the financial burden of bioterrorist events.
