The infection routes for biological agents in bioterrorism include inhalation, ingestion, dermal exposure, and injection. The potential agents under development could include anthrax, smallpox, plague, and botulinum toxin, which might be deployed using missiles, artillery shells, or through covert operations. Proximity to North Korea significantly increases vulnerability to biological attacks. Possible methods include contaminating water supplies, food sources, or densely populated areas. Anthrax, smallpox, plague, and botulinum toxin could theoretically be delivered using packages attached to balloons. Minimizing the impact of a bioterrorism event requires strategy that includes four key actions: detection, decision-making, distribution, and dispensation. By integrating these steps, authorities can effectively manage and mitigate the effects of a bioterrorism event.
