Analytic Reviews: Management of Patients Exposed to Biological and Chemical Warfare Agents

Abstract

Biological and chemical weapons have been used for waging war since the dawn of recorded history. Recently, these agents have been used on civilian populations by terrorist groups. Terrorist attacks using biological or chemical weapons have far-reaching implications, as they cause widespread fear, anxiety, and panic among the public. Biological agents have particular appeal for use in terrorist attacks because they are reasonably easy to acquire, are inexpensive to produce, and have the potential to affect large populations of people. Biological agents are selected based on their toxicity, ease of production and stability, and ability to be dispersed in respirable aerosols. The most common biological agents that have been weaponized include anthrax, plague, tularemia, botulism toxin, and smallpox. Chemical agents are more expensive and more difficult to manufacture and deploy and are therefore more likely to be used in conventional warfare. Mustard gas and nerve agents are the favored chemical agents of mass destruction.
