Questions and Answers
Why is person-to-person spread NOT a primary concern in anthrax infections?
Why is person-to-person spread NOT a primary concern in anthrax infections?
- Anthrax primarily affects animals, with human cases being rare and isolated.
- The bacteria become active only when they enter a living host; they do not readily spread from person to person. (correct)
- The bacteria require an intermediate vector, such as insects, to transmit the disease between individuals.
- Anthrax spores must undergo a period of dormancy before they can become infectious.
What is the primary function of antibiotics, such as Ciprofloxacin, Doxycycline, or Penicillin, in treating anthrax infections?
What is the primary function of antibiotics, such as Ciprofloxacin, Doxycycline, or Penicillin, in treating anthrax infections?
- To repair the tissue damage caused by the anthrax toxin and promote the regeneration of affected cells.
- To inhibit the growth and replication of Bacillus anthracis, thereby reducing the bacterial load in the body. (correct)
- To stimulate the immune system to produce antibodies capable of targeting and eliminating the anthrax bacteria.
- To neutralize the anthrax toxin directly, preventing it from binding to host cells.
What implication does the limited availability of the anthrax vaccine have on public health preparedness strategies?
What implication does the limited availability of the anthrax vaccine have on public health preparedness strategies?
- Stringent quarantine measures are in place for confirmed cases to prevent widespread dissemination of the disease.
- Mass vaccination campaigns are not feasible, necessitating a focus on post-exposure prophylaxis for high-risk groups. (correct)
- Resource allocation is directed towards research and development to enhance the vaccine's efficacy and production capacity.
- The vaccine is reserved for emergency responders and healthcare workers, given their higher risk of exposure.

Study Notes
Biological Warfare Agents
- Warfare agents are biological or chemical substances that can cause mass casualty destruction or fatality.
Anthrax
- Bacillus anthracis (B. anthracis) causes anthrax and may be contracted via the digestive system, skin abrasions, or inhalation.
- Direct contact with the bacteria and its spores transmits anthrax. Spores are dormant encapsulated bacteria that become active when they enter a living host.
- Anthrax is not transmitted person-to-person.
- The infection of anthrax is carried to the lymph nodes, spread to the rest of the body via the blood and lymph, and causes shock and death due to high levels of toxins.
- Anthrax in the lungs can cause fluid buildup, tissue decay, and death if untreated.
- A blood test can detect anthrax by detecting and amplifying B. anthracis DNA if present in the blood sample.
- Antibiotics like ciprofloxacin, doxycycline, or penicillin are used to treat anthrax.
- Anthrax Vaccine availability is limited.
Smallpox
- Smallpox is transmitted in air droplets and by handling contaminated materials, and its transmission is highly contagious.
- Symptoms of include fever, back pain, vomiting, malaise, and headache and begin 7 to 17 days after exposure .
- After two days after symptoms develop, papules develop and progress to pustular vesicles initially abundant on the face and extremities.
- A vaccine is accessible to those at risk for exposure to smallpox.
Botulism
- Clostridium botulinum produces a nerve toxin that causes serious paralytic illness that is known as botulism (death can occur within 24 hours).
- Botulism spores are found in the soil and spread through the air or food (particularly improperly canned food) or a contaminated wound.
- Symptoms of botulism include abdominal cramps, diarrhea, nausea, vomiting, double vision, blurred vision, drooping eyelids, difficulty swallowing or speaking, dry mouth, and muscle weakness.
- After ingestion of food-borne botulism for 12 to 36 hours and after inhalation for 24 to 72 hours, neurological symptoms begin and can progress to paralysis of the arms, legs, trunk, or respiratory muscles, and mechanical ventilation is necessary.
- If diagnosed early, food-borne and wound botulism can be treated using an antitoxin that blocks the action of toxin circulating in the blood.
- No vaccine is available for botulism.
