COVER STORY: BIOTERRORISM
THE ANTHRAX FILES
1.Inhalation:
The deadliest form of infection, with 90 per cent fatality. When mixed
with powder, anthrax spores are more easily inhaled. Influenza-like symptoms
of fever and nausea occur.
2.Ingestion: After eating infected meat,
symptoms like nausea, retching, abdominal pain and fever occur, followed
by meningitis. Half the patients die if not treated promptly with antibiotics.
3.Skin Contact: Common route of infection
through broken skin, after touching infected animal hides. Rashes appear
after a couple of days and blacken after turning into fluid-filled vesicles.

What is Anthrax?
The
bacterium Bacillus anthraxis which causes anthrax, is a popular bio-weapon
as its spores are heat-resistant and can stay alive for over 100 years.
Once inside the body, the hard-shelled spores reproduce and discharge
toxins that eventually cause organ failure.
The
Treatment
Anthrax in the early stages can be treated by antibiotics like ciprofloxacin
or penicillin taken for 60 days. But once the toxin is released, antibiotics
do not help.
OTHER SCARES
SMALLPOX
Variola
Virus: It is hardy and deadly, making it an ideal weapon. It kills
one in three people it infects. It spreads from person to person. Symptoms
include high fever and a rash. There is no cure, but vaccines taken after
infection could prevent death.
PLAGUE
Yersinia Pestis: "The Black Death' is highly contagious
and almost always fatal if untreated. Symptoms, including fever and delirium,
appear in three or four days when the bacteria reaches the lungs. Antibiotics
are effective when administered promptly.
BOTULISM
Clostridium
Botulinum: This deadly nerve botulinum toxin seeps through the
gut, lungs or broken skin, paralysing before killing. Initial symptoms
are nausea diarrhoea, slurred speech, and dizziness. An antitoxin can
sometimes arrest the process.
TYPHOID
Salmonella Typhii: It spreads easily through food and drink.
It causes typhoid fever, with high temperature, weakness and loss of appetite.
Antibiotics like ciprofloxacin are effective.
