Medical personnel may be the first to detect a biological warfare attack by
recognizing an outbreak of illness that does not fit with normal baseline disease patterns in
the population that they serve. Some characteristics include the wrong disease for a locality
and time, extreme virulence, high case fatality rates, wide separation of point source
outbreaks of the same illness, and simultaneous outbreaks of two or more unrelated
illnesses. As with chemical warfare agents, biological agents can be lethal, such as anthrax
and botulinum toxin, or only incapacitating, such as SEB. Some biological agents, such as
anthrax spores, may be extraordinarily persistent under certain climatic conditions.
Desirable characteristics of a biological warfare agent from the point of view of an aggressor
might well include short incubation period, ease of production and storage, high virulence,
and existence of an effective vaccine or therapy in the hands of the user. Known natural
occurrence of the same disease in the target area would be desirable for deniabilty of actual
use. Extreme contagiousness of a disease, on the other hand, would be a disadvantage,
putting the aggressors own troops or population at risk.
In view of the openly reported holding by Iraq of anthrax, botulinum toxin, and SEB,
military physicians should become familiar with the standard text descriptions of the illnesses
caused by these agents. The most probable means of dissemination of the agents is by
aerosol. Our standard chemical protective masks and MOPP gear provide 100% effective
protection against these aerosolized agents. Biological fluids such as blood and urine may
be submitted for testing when medical personnel suspect a biological attack. A sample
collection team with appropriate contairunent, chain of custody, and security capability for
this purpose should be requested through unit intelligence channels.
Anthrax is a natural ariimal disease of herbivores produced by the Gram positive
spore-fomiing organism Bacillus anthracis. Until the development of an effective vaccine,
it was a major problem for workers in such occupations as wool sorting who were at risk for
contracting inhalation anthrax, the most severe of three forms of the disease. Most cases
of human anthrax are cutaneous, consisting of a painless papule that forms a pustule, often
surrounded by satellite lesions. 'ne boxcar-like organisms can be seen in smears of the
pustule, response to penicillin therapy is good, and case fatality is low. Gastrointestinal
anthrax, resulting from ingestion of heavily contaminated or undercooked meat, may cause
enteritis, hemorrhagic mesenteric adenitis, ascites, and sepsis, but also responds well to
penicillin therapy.
The most severe form of anthrax results from inhalation of spores, which have their
best capability of penetrating to the alveoli in particles of size 3 to 5 microns. After a short
incubation period of 1 to 6 days, a biphasic illness begins with a multisystem influenza-like
prodrome, followed by a severe phase characterized by hemorrhagic mediastinitis with a
widened mediastinum and clear lung fields on chest films, and sepsis often leading to
meningitis. The case fatality rate for inhalation anthrax is over 90%, even with high dose
intravenous penicillin therapy. The anthrax vaccine provides effective protection from
aerosol exposure in industry after a 2-shot primary immunization series. Recent work at
dose administered promptly after inhalation
