Possible Biological Weapons Anthrax bacteria
transmitted through skin, inhalation, and
gastrointestinal tract highly lethal when
inhaled. It does not spread from person to
person. An anthrax vaccine does exist, but is not
readily available. Antibiotics are used to treat
anthrax. Smallpox virus highly contagious
spread by air and direct contact high mortality
rate. Smallpox has killed more people over time
than any other infectious disease, including the
plague. Cholera bacteria transmitted through
water and food. Treatment involves replacing
fluids and salt lost through diarrhea and
vomiting. Plague bacteria highly contagious
transmitted by fleas high mortality rate. It
causes a type of pneumonia and can be fatal if
not caught early. Antimicrobials are used to
treat the disease. Botulism one of the
deadliest toxins caused by bacteria can be
inhaled or ingested. Severe botulism causes
respiratory failure and paralysis. Antitoxins and
assisted ventilation are used to treat the
disease. Ebola virus causes hemorrhagic fever
extremely lethal spread through direct contact
with blood and body fluids symptoms are profuse
bleeding from body openings. There is no cure or
treatment. Meningitis bacteria spread through
direct contact. Bacterial meningitis is serious
and requires urgent treatment with antibiotics to
prevent permanent damage or death. There is a
vaccine for the most common form of bacterial
meningitis (Hib).

How Communicable Diseases Spread

• Airborne
• Water-borne
• Carried in Food
• Direct Contact
• Contact with a carrier
• Contact through a wound.

How Non-communicable Diseases Spread

• Environment
• Diet
• Lifestyle
• Genetic

5
Scenario 1 A pregnant woman unknowingly passes
the virus to her unborn child after contracting
it from her partner.
6
Scenario 2 A man who knows he is carrying the
AIDS virus continues to have unprotected sex with
others without telling them.
7
Scenario 3 A small group of drug users routinely
share needles when getting high. One of them
knows she has AIDS but does not tell the others.
8
Scenario 4 A man unknowingly received the AIDS
virus during a blood transfusion that occurred
before blood was screened for AIDS. He
transmitted the virus to his partner.
