Reclassifying bioterrorism risk: are we preparing for the proper pathogens?

Area of Science:

• Biosecurity and threat assessment
• Microbiology and infectious diseases
• Public health policy

Background:

• Current biological weapon classifications are limited, overlooking crucial pathogen and socio-political factors.
• These overlooked factors significantly influence the outcome of potential biological attacks.
• A comprehensive risk assessment is needed to accurately evaluate bioweapon potential.

Purpose of the Study:

• To develop a novel classification system for biological weapon potential.
• To integrate pathogen characteristics with socio-political context for a more accurate risk assessment.
• To re-evaluate the perceived risk of specific biological agents.

Main Methods:

• Development of multiple biological attack scenarios.
• Calculation of individual scores for pathogen and socio-political factors based on scenario outcomes.
• Creation of a new scoring system to classify biological weapon potential.

Main Results:

• The new classification score significantly alters risk perceptions for agents like filoviruses and anthrax.
• It allows for a more precise evaluation of the bioweapon potential of agents such as avian flu.
• Identified key intervening factors influencing attack outcomes.

Conclusions:

• A nuanced approach considering both biological and contextual factors is essential for accurate bioweapon risk assessment.
• The developed framework enhances the evaluation of emerging threats like avian flu.
• Improved risk assessment can guide resource allocation for relevant medical research and biodefense strategies.
