One thing that certainly has people on edge throughout this War on Terror
is
the worry that some extremist group will plague parts of the world with a
deadly,
and possibly contagious, biotoxin.
The fear briefly became reality in the
U.S. after
9/11, as man-made anthrax spores were found in letters and in east coast
post
offices on a number of occasions.
Mysteriously, the attacks ended almost as quickly as they had begun. But
they
were so frightening to many U.S. citizens that a new term --
bioterror
--
was soon burned into the American consciousness.
Those attacks also showed the panic and very real danger posed by the
release of such toxins on an unsuspecting public.
Dealing With Bioterror
Many Americans now wonder how they can protect themselves from a release
of a potentially deadly biotoxin, bacteria, or virus. Authorities are urging
people to
become familiar with the early symptoms of things like anthrax, and report
any
suspicious letters or packages to law enforcement.
While people clearly need to worry about exposures to various chemical
and
biological agents during these trying times, the mail attacks right after
9/11 quickly
put anthrax front-and-center in the minds of many Americans.
Continued below...

In a way, that early emphasis on the perils of anthrax exposure may have
actually aided the U.S. in its fight against a bioterrorist attack.
Bioterror
experts say
that the symptoms of an anthrax exposure are the easiest to deal with as
long as
one is treated soon after exposure. The flu-like symptoms may persist
for
as
long as three days before becoming worse; although once the severe stage
sets
in,
death can occur in as little as two hours or up to two days.
Death Can Happen Fast
There is no known cure once the anthrax infection becomes severe, note
researchers.
That problem showed governments everywhere the necessity of a rapid
response to a bioterror attack, since a large segment of a nation's
population may
die if those with the infection are not quickly and properly treated.
What Is Anthrax?
One thing to note is that bioterror experts actually know very little about anthrax --
which is the
real reason for their overall silence on the subject. After all, anthrax is
something
little-seen this day and age in the West, and our knowledge of it is spotty
at best.
This is not to suggest that the experts know nothing about its symptoms;
they
simply are not as certain about anthrax as they are about smallpox, for
example.
So while microwaving mail probably won't kill any spores, it won't
really hurt anything to continue doing just that if you've been microwaving
letters
since 9/11. Though be careful; some experts have recorded cases of people
starting serious fires in their microwaves as they 'nuked' their mail. If
you decide to
do this, be cautious of the dangers.
Should people stockpile antibiotics?
Some people are stockpiling antibiotics -- a practice health officials
are
concerned will lead to dangerous side effects and drug-resistant germs.
Still
others
are toting around gas masks purchased from Army surplus stores.
Gas mask may be useless
"Purchasing a gas mask and having that around increases, if you will, the
terror
associated with these incidents and brings it home in a way that is
unnecessary
because you would never know when to put that gas mask on," said Dr. Sue
Bailey, former assistant secretary of defense.
Granted -- but isn't there anything people can do to protect
themselves?
"They should learn more about anthrax so they know what it [certainly] is
and
what it isn't," Coffin advised.
What Is Anthrax?
Anthrax spores can enter the body through a cut or abrasion, or it can be
inhaled. They are usually in the form of a fine white or brownish, grainy
powder.
The cutaneous form of anthrax is contracted through the skin, via
a
cut
or abrasion. Three to five days after infection, a painless blister appears.
A day or
two later, this becomes a black, open sore. Cutaneous anthrax accounts for
95
percent of anthrax cases in the United States, and is easily treated with
antibiotics.
But left untreated, perhaps 5 percent of cases progress to a dangerous
bloodstream infection, which is almost always fatal.
The inhaled form of anthrax incorporates the same germ as the cutaneous
form; however, inhaled anthrax is both rare and extremely deadly. Studies of
previous cases indicate that a dose of just 2,500 to 55,000 anthrax spores
is
lethal
to about half of the people who inhale them.
The first stage of inhaled anthrax infection, lasting from hours to a few
days,
involves flu-like symptoms, including fever, coughing, weakness and chest
pains.
Only at this stage can inhaled anthrax be treated with antibiotics.
The second stage usually ends in death within days. Lung damage deprives
the
body of oxygen. The victim then goes into shock. Brain infection may also
occur.
Antibiotics only prove helpful at the earliest stages of the disease because
they fight
bacteria, not the toxins the bacteria produce in abundance during the final
stage of
infection.
Antibiotic Warning
Three types of antibiotics are approved for preventing and treating
anthrax in
its early stages: ciprofloxacin, tetracyclines and penicillins. People who
have been
exposed to the germ but do not have symptoms are given an antibiotic for 60
days
to reduce the risk of developing the disease.
What people should not do, health officials say, is demand
antibiotics
from their doctors. The reason is simple: "If these drugs are used
inappropriately,
the organism is going to develop resistance to them. The worst thing you can
do is
contribute to these organisms becoming resistant," said U.S. Surgeon General
David Satcher.
Health and Human Services Secretary Tommy Thompson has asked people
not to hoard anthrax antibiotics, saying the government had enough to treat
those
who might require the drugs. A more reliable form of protection, many say,
is
to
simply keep an eye on unusual letters or packages arriving in the mail.
Examine Packages
Besides the telltale fine white or brownish, grainy powder on or in a
piece of
mail, the FBI says several things can tip you off about a questionable
letter
or
package:
*misspelled words or wrong titles on the label;
*having been sent from an unknown person in a foreign country;
*having excessive postage or no return address;
*restrictive markings such as "personal";
*oily stains, discolorations or crystallization on the packaging.
If you receive an envelope and there's a powder inside, set it down
carefully,
don't move it or give it to anyone else, quickly wash your hands with soap
and
water and call 911.
The flip side to all this is that most Americans probably won't have to
worry
about such a threat: most of those actually targeted in the anthrax attacks,
after all,
were public officials and journalists. Experts therefore say there is very
little reason
to suspect you've been exposed unless there has been a specific incident
where
you live or work.
"It's just not a big enough threat for most people to be worrying about,"
said
Dr. Henry Rosen, a professor of medicine and expert in infectious diseases
at
the
University of Washington in Seattle. "It's a threat that has been
tremendously
exaggerated. How often do you worry about things that effect two or three
people
in 300 million?" he said.
Rosen said he is more concerned about the ill effects of constantly
living
in fear
of bioterrorism. "The health effect from the anxiety of this is probably
bigger than
the overall threat from [such things as] anthrax," Rosen said.
The Top Peril: Smallpox
But as health authorities ramp up to deal with the potential threat posed
by
anthrax, an even bigger effort is focusing on what many consider the top
bioterror
peril: smallpox. Smallpox and anthrax lead the list of potential biological
weapons
capable of devastating civilian populations, along with plague, botulism and
hemorrhagic fever.
Experts say smallpox would be a very effective bioweapon, both because it
kills 30 percent of its victims and it has a long incubation period. It may
take up to
two weeks for symptoms to appear; but after that time, the victim may
develop
high fever, malaise, headache and backache. Two days after symptoms start, a
rash of pus-filled boils develops, spreading all over the body. Smallpox is
easily
spread, and there is no known treatment for one who has contracted the
disease.
For centuries smallpox was a worldwide terror, one spread through
coughing,
sneezing or physical contact -- even by handling the bed linens of the
afflicted.
But thanks to a global vaccination effort begun by the old Soviet Union,
by the
late 1970s the virus' domain had been contained to a few tightly controlled
laboratories in Russia and the United States.
That's indeed something for the Reds to be proud of; yet we shouldn't pat
the
old Soviets on the back just yet. There are rumors in U.S. intelligence
circles that
the Russians, along with Iraqis and North Koreans, have held onto
undisclosed
stores of smallpox for weapons purposes.
Russia said to have large stockpiles of smallpox for bioweapons
Defector Ken Alibek has
acknowledged
that the Soviets built up large stockpiles of smallpox in the 1980s for use
in
bioweapons, and terrorism experts worry that virus samples could somehow
find
their way into terrorist hands.
America at risk of smallpox attack
So how are Americans protected? U.S. health authorities stopped
recommending routine vaccinations for smallpox in 1971. Even those immunized
before that time are unlikely to still be protected. We are all sitting
ducks, in a
phrase.
And that, dear friends, is what makes smallpox so very dangerous.
But don't head for the hills just yet, folks. There are arguments against
smallpox being used as an instrument of bioterror.
Remember, unlike anthrax, the human smallpox virus was virtually
eradicated
in the late 1970s, and the only known stores are in Russia and the U.S. Both
countries have sworn to a war against terrorist activity after the events of
9/11. All of
this would presumably make it far more difficult for an extremist person or
group to
obtain smallpox for bioterror purposes.
Smallpox highly contagious, much more dangerous than anthrax
The final analysis regarding smallpox? "It's a less likely threat than
anthrax, but
potentially more catastrophic, because it's contagious," says Dr. Jonathan
Tucker,
author of a book on smallpox titled "Scourge" and director of the Chemical
and
Biological Weapons Nonproliferation Program at the Monterey Institute of
International Studies.
Smallpox: Low-tech weapon
Samuel Watson, co-director of the BioMedical Security Institute at the
University of Pittsburgh Graduate School of Public Health, reluctantly told
MSNBC in late 2001 that the anthrax cases after 9/11 could have an effect on
the
whole bioterror debate, and especially over smallpox concerns.
"If this thing in Florida with the anthrax turns out to be a strain that
the Soviets
had, or if it turns out to be a strain that the Iraqis had, or Iran or North
Korea, or if
we had it only in a (Centers for Disease Control and Prevention) lab -- if
that turns
out to be the case, then I think we need to be worried about smallpox," he
said.
According to Dr. Raymond Zilinskas, deputy director of the Chemical and
Biological Weapons Nonproliferation Program, the main danger is that a
smallpox
attack wouldn't require the highly technical dispersal mechanisms that
terrorists
need to spark a widespread anthrax outbreak.
"With smallpox, you don't need any of that, you just need infected people
...
the biological equivalent of a suicide bomber," he said.
Making More Vaccine
That's why the CDC is once again building up the nation's long-dormant
stocks of smallpox vaccine -- a store that currently could be used to
vaccinate 7.5
million to 15.4 million people.
In 2000, a year before 9/11, the CDC put in a $343 million order with the
company Acambis for the production of 40 million doses of a new smallpox
vaccine at its facility in Cambridge, MA; the order however would not be
filled until
2004. But in the wake of the anthrax attacks, the timetable was accelerated
so that
those doses would be available by the end of 2002 -- even though the vaccine
would still lack the Food and Drug Administration's full approval.
"It could only be administered with informed consent," Tucker explained.
The
vaccine still has to go through years of testing before it could be
administered
routinely, however.
In the meantime, researchers at four medical centers -- Baylor College,
the
University of Rochester, St. Louis University and the University of Maryland
-- are
investigating whether the existing vaccine would work even if it were
diluted
fivefold
or tenfold. That would stretch out the nation's supply to serve 75 million
people or
more, a much more comforting scenario.
"75 million doses still not enough"
Tucker said the results so far were encouraging, but even 75 million
doses
were "still probably not enough for a worst-case attack."
Other researchers are trying to develop anti-viral drugs to fight
smallpox
cases,
but it will take years to turn that research into safe medications.
Even in the wake of the suicide attacks on the World Trade Center and
Pentagon on 9-11, some experts like Zilinskas find it hard to believe that anyone
would
seriously attempt to unleash smallpox on the world again.
"Even though (Iraqi leader) Saddam Hussein is ruthless, I don't think he
is
completely reckless," he said. "You'd have to be reckless, because if you
have
these things you must know that everyone is vulnerable... . The pandemic
would
spread to other parts of the world, including Iraq, and they're just as
vulnerable as
anyone else in the world."
Of course, he's not considering the fanatical beliefs of Iran and Radical Islam. They're likely to believe
that "Allah" will protect them from the effects of smallpox, if they could ever get their
hands on and to use it as a weapon.
Best Bioterror Clue: Flu Drug Sales
Researchers at Carnegie Mellon University have stated that monitoring
sales of
nonprescription drugs might help provide early detection of a bioterror
attack,
according to the Associated Press (AP).
For instance, since early symptoms of deadly inhaled anthrax are similar
to the
flu, a sudden increase in sales of flu medications could tip off authorities
to check
for anthrax before victims become ill enough to seek medical attention, the
researchers suggest.
The Carnegie Mellon project was started long before the anthrax mail attacks
in
late 2001, said Stephen E. Feinberg of the university's department of
statistics.
He added the group's focus is on larger scale attacks in an urban area, not
the
relatively limited hazard posed by the mailed germs.
"We're talking about exposures of thousands of people in a concentrated
location, and then you've got very large-scale impact to assess and every
second
counts," Feinberg explained.
"In search of unusual outbreaks of disease"
Scientists already watch sales of antibiotics in search of unusual
outbreaks of
disease. Systems such as the one proposed by Carnegie Mellon researchers
would
extend that to over-the-counter medicines as well.
Gregory C. Gray, an epidemiologist at the University of Iowa, said there
is
precedent for using such sales to detect disease. An outbreak of the
intestinal
parasite cryptosporidium in Milwaukee in the early 1990s was first detected
by
pharmacists who noticed a run on antidiarrheal medicines, he said.
The Carnegie Mellon work focused on sales of cough medicine and the
system
had trouble detecting a flu outbreak during a holiday, but the study could
point the
way to developing a more broad-based method for detecting bioterrorism
attacks.
That will have to take into account seasonal sales patterns, local flu
outbreaks,
cut-price sales, store hours and other factors that affect how much of a
product is
sold.
According to Carnegie Mellon's Stephen Feinberg, the long-term goal is to
develop a system looking at cough syrups as well as pain pills, stomach
medicines
and other drugs so analysts can create a "footprint" of sales and detect
unusual
patterns.
"Cough medicine has a lot of variability. You have a set of symptoms
working
in concert and if you can look at an ensemble of symptoms, you clearly will
have a
more accurate system for detection," he explained.
If the system signaled an alarm, he said, local public health officials
could be
alerted. They would determine if an actual bioterror attack were underway
before
the public is unnecessarily alarmed, Feinberg added.
That, he said, could give officials a head start toward reducing the
number of
deaths if an attack were occurring.
Can biological agents be detected on radar?
On top of the millions already allocated to states, the Army is launching
a
series of experiments to see if clouds of chemical or biological agents can
be
detected on radar. There will be test sprays a few miles from Key West,
Fla.,
using safe materials with properties similar to potential threats to see if
the radars
can tell them from rain or clouds.
Such sweeping governmental moves would probably never have occurred
without the attention newspapers and other news outlets have brought to the
problem. But there is a sad part about the American media's fixation on
bioterror.
According to a supposed statement released in December 2001 by Aiman
al-Zawahiri, Al-Qaeda's real military leader, it apparently never occurred
to
the
group to use something like anthrax against its targets until 1998, after
the
group's
bombing attack on the U.S.S. Cole. Operatives began reading worried reports
published by U.S. media outlets on the possibility and inherent danger of
bioterror
attacks -- and the rest, as they say, is history.
All the same, these efforts by both scientists and government officials
to
fight
bioterror are now necessary. But with the rise of rogue governments like Iran and North Korea, and probably alliances with powerful nations like Russia and China, it seems more likely each year that some kind of bioweapon or other weapon of mass destructions will make it's way into the hands of a terrorist organization willing to use it.
