Plague.

In the United States, plague poses a threat to humans from the infected animals in the endemic areas of the Western states. Plague may also be used in the near future as an agent of warfare or terrorism. Although the presentation of bubonic plague may be less of a problem, the septicemic and pneumonic forms present challenges to early diagnosis and prompt treatment. The major threat of plague as an agent of terrorism will probably be through the inhalational route. which could result in many cases of the pneumonic form, requiring early recognition and initiation of appropriate therapy. In a mass-casualty scenario, the clinician should be aware of the potential agents of biowarfare and be familiar with the treatment and prophylaxis recommendations outlined by the CDC. It is also prudent to employ universal precautions and respiratory isolation when treating patients with any unknown exposure. In endemic areas, personal protective measures such as use of insecticides, insect repellants, and prompt prophylaxis in cases of exposure to plague are recommended for reducing the incidence of infection. The author also recommends review of CDC website on bioterrorism (http://www.bt.cdc.gov) to keep informed of plague updates.

Bacteria as agents of biowarfare. How to proceed when the worst is suspected.

Recognition of an increasing incidence of uncommon pneumonias with a high mortality rate, clusters of cases, or a high incidence of pet illnesses or death should alert medical personnel to the possibility of terrorism with bacteriologic agents. Prompt reporting of such unusual occurrences to the local health department is of paramount importance for early identification of cases, treatment initiation, and institution of preventive measures.

Defending against viruses in biowarfare. How to respond to smallpox, encephalitides, hemorrhagic fevers.

The threat of bioterrorism with use of viruses is increasing. Smallpox, encephalitis, and hemorrhagic fevers are the most likely diseases to result from viral deployment. It is critical that all healthcare professionals become familiar with the clinical presentation, diagnosis, management, and prevention of these diseases. Awareness and preparedness are instrumental in reducing viral transmission and improving survival of the victims.

When biotoxins are tools of terror. Early recognition of intentional poisoning can attenuate effects.

Toxin-mediated diseases have made humans ill for millennia. They also have been used in beneficial ways. Unfortunately, the use of biological agents as weapons of terror has now been realized, and separating naturally occurring disease from bioterroristic events has become an important public health goal. The key to timely identification of such attacks relies on education of primary care physicians, first responders, and public health officials. We must remain vigilant to unusual case presentations or clusters of similar cases and report them immediately to public health authorities.

Vesicants and nerve agents in chemical warfare. Decontamination and treatment strategies for a changed world.

Vesicants and nerve agents have been used in chemical warfare for ages. They remain a threat in today's altered political climate because they are relatively simple to produce, transport, and deploy. Vesicants, such as mustard and lewisite, can affect the skin, eyes, respiratory system, and gastrointestinal system. They leave affected persons at risk for long-term effects. Nerve agents, such as tabun, sarin, soman, and VX, hyperstimulate the muscarinic and nicotinic receptors of the nervous system. Physicians need to familiarize themselves with the clinical findings of such exposures and the decontamination and treatment strategies necessary to minimize injuries and deaths.
