Chemical and
biological warfare --CBW-- has been employed for hundreds, and probably
thousands, of years in ways that might now be considered “primitive.” Modern
advances in science and technology make warfare by such means a greater threat
today. The new CBW weapons are deadlier, and there are now more opportunities
for using them. They have been employed occasionally in wars between nations,
and more systematically during World War I. Since the 1990s these weapons have
also been used by terrorist groups in attacks on their enemies and in attempts
to draw attention to their objectives. Biological terrorism --bioterrorism for
short-- is one of the main threats of the 21st century because terrorist groups
have learned out to obtain and deploy biological and chemical weapons. And
America is a likely target for an attack.
Bioterrorism remains for many people an unknown area. The country as a whole
needs to take some steps to enhance protection. Since September 11, 2001 much
has been done to plan and organize national defenses. These defenses are
essential, but they often seem to be at too great a distance from individuals.
Individuals, too, need to plan to defend themselves. The goals of this pamphlet
are to explain how to recognize what are regarded as the leading bioterrorist
threats, and to provide suggestions about what to do in the event of an attack.
Our aim is to inform rather than to alarm. The main premise of this pamphlet is
that everyone can learn how to recognize the diseases and toxins likeliest to be
used in bioterrorism, and everyone can learn some useful steps to take against
each specific disease and toxin.
Early detection of terrorist attacks will save lives, quite dramatically for
some agents. That means that individuals need to know how to recognize and
detect the weapons of bioterrorism, or at least when to be suspicious that such
weapons have been used. And it means getting in touch immediately with local and
national authorities.
Bioterrorism is the use of bacteria or viruses or a chemical compound with the
intent of making people ill or causing death. These diseases and chemicals can
be spread through the air or water, and by direct contact. Following a
categorization introduced by the Centers for Disease Control, we distinguish two
groups of diseases. Category A diseases are the most dangerous and the likeliest
to be used in bioterrorist attacks. Category B diseases are less lethal and are
less likely to be used, but they are still considered dangerous disease agents.
Terrorists may elect to use biotoxins and chemical weapons as well as diseases,
selecting toxins that cause sickness or death in a large proportion of the
people who come into contact with them, and which have a more or less immediate
effect. The biotoxins, such as ricin, SEB, and T-2, use live organisms to make
chemicals. Other weapons are made from chemical agents. There is no sharp
dividing line between biotoxins and chemicals.
Each chapter below discusses a particular disease or toxin, or aspects of
bioterrorism that concern individuals, such as likely targets, delivery methods,
and how to respond. The chapters on diseases and toxins are organized in a way
meant to help readers find topics and obtain information quickly.
Many diseases and compounds could be used as weapons. Here we select those that
are widely considered the likeliest ones to be used. For a bacteria, virus or
chemical compound to threaten us, it must be easily produced and transported,
and it must either be powerful enough to affect many people or able to cause
disease or injury with unusually small doses. Diseases and agents that are
difficult to detect immediately are also attractive for use in bioterrorism. One
chapter is devoted to each disease or compound, giving a brief overview. Each
chapter explains how to recognize a disease or agent, and what to do with
yourself, others, and your belongings if an attack is suspected.
Biological weapons and toxins are appealing to terrorists because such weapons
can affect a large number of people and because some of them can be produced
with relative ease. A person with limited scientific training may be able to
cultivate bacteria or viral agents in a small space without expensive equipment.
The production of weapons of this kind is usually easier than making other
weapons of mass destruction, such as a nuclear bomb. The quantity of material
needed to sicken or kill many people varies from agent to agent, but for the
most part more damage can be done with a smaller quantity of a disease or a
biological agent than with other types of weaponry.
There are also important disadvantages to using biological weapons. One problem
of producing and transporting a biological weapon made from a living organism is
that the environment of the weapon must be carefully maintained. Most organisms
will not survive exposure to extreme heat or cold, and some do not have a life
span long enough for their production, transportation, and delivery as
bioterrorist weapons. Another problem that might discourage the use of a
bioweapon is the challenge of containing the weapon to one specific area while
protecting the attackers. It may be impossible or impractical to prevent the
weapon from affecting the very people using it in an attack.
Biological and chemical weapons may or may not threaten Americans in the future;
it is impossible to know. We can hope that we never need to use the information
in this pamphlet. Still, it is useful to know how to recognize such weapons and
how best to protect ourselves in case of an attack. Good understanding of the
nature of the threat can help us protect ourselves, our family members, and our
friends, and help public health authorities reduce the damage to our community
and our nation. |
