In his first inaugural address in 1933, President Franklin
Delano Roosevelt inspired a battered nation with these words: "The only
thing we have to fear is fear itself -- nameless, unreasoning, unjustified
terror which paralyzes needed efforts to convert retreat into advance."
Instilling fear is a terrorist's stock in trade. But as FDR
knew, the best antidotes to unreasoning, unjustified terror are knowledge,
strength, and preparedness. Seventy years after he spoke those words to a
nation beaten down by the Great Depression, we again face an
uncertain economic future, and the even grimmer prospect of biological
In every issue of WebMD the Magazine, we ask experts to answer readers' questions about a wide range of topics, including questions about what's true and not true in the field of medicine. For our July/August 2012 issue, we interviewed a University of Utah researcher about the danger of using a phone behind the wheel.
Q: I've read that driving while talking on a cell phone is as bad as driving drunk. Is that true?
A: Many people can't imagine not chatting on the phone while driving. But...
Biological terrorism, or bioterrorism, is the use of
disease-causing agents to spread death and destruction and strike fear into the
heart of a target population.
It has an ancient and dishonorable history: In the Dark Ages,
armies used catapults to fling plague-ridden corpses over castle walls. In 1763,
British commander Lord Geoffrey Amherst ordered the distribution to Native
Americans of blankets that had been used by victims of smallpox. And in more
recent times, biological weapons were used against livestock and civilians
during both World Wars.
"In theory, biological weapons could be even more
devastating than chemical or nuclear weapons. That's because some of them can
spread far beyond the initial point of release through ongoing and multiplying
human-to-human transmission," write David Ropeik and George Gray, PhD, from
the Harvard Center for Risk Analysis in their book Risk: A Practical Guide
for Deciding What's Really Safe and What's Really Dangerous in the World Around
The U.S. Centers for Disease Control and Prevention (CDC)
divides biological agents into three categories -- A, B, and C -- based on
their ability to wreak havoc on the population at large. Category A or
"high priority" agents are those that can be easily transmitted through
human contact, have a high death rate and the potential for a major public
health impact, may cause widespread panic
and disruption, and require special public health measures. Agents in this
category are in alphabetical order:
As the attacks of September 11, 2001 made starkly evident,
terrorists may try to strike at civilian targets such as high-rise buildings,
transportation hubs, sporting events, and public spaces such as malls.
Terrorists might choose to spread an infectious disease by
facilitating person-to-person contact, or by deploying agents that have been
"weaponized." For example, an infectious disease that normally infects
the skin could be turned into an
aerosol or powder form that could then be sprayed over a wider area, said an
emergency response expert from the U.S. Department of Health and Human
Services, who spoke with WebMD on background.
There are several notorious examples of small-scale biological
and or chemical attacks in recent memory. In 1984, followers of the Indian guru
Bhagwan Shree Rajneesh deliberately contaminated salad bars in 10 restaurants
in Western Oregon; more than 700 people were poisoned. The group supposedly
carried out the act, said to be the first documented case of bioterrorism in
modern U.S. history, as a test of a plan to contaminate the local water supply.
Their alleged motive was to prevent people from voting against cult-backed
candidates in a county election.
