What are the 6 category A biologic agents?
- viral hemorrhagic fever
Why are category A agents considered such?
- relatively easy to disseminate
- high mortality rate
- high infectivity
- little to no treatment
Is anthrax contagious?
What is the key identifier for anthrax?
widening of the mediastinum
How do we prevent anthrax?
- 5 shot series
- ABThrax (still not approved, but in the SNS stock)
How do we treat anthrax?
- Doxycycline x 60d (prophylaxis)
- Ciprofloxacin x 60d (prophylaxis & tx)
- Amoxicillin (susceptible bugs only)
- usually add 1-2 more AB's to this regimen (rifampin, vanco, chlorampenicol, clindamycin, clarithromycin, imipenem, PCN, ampicillin)
- STILL TREAT PREGNANT WOMEN - death if we don't
What is the mortality rate of anthrax?
100% if untreated
How does anthrax kill you?
- lethal factor toxin
- protective factor toxin
- edema factor toxin
- (any one of these gets to high enough level means no tx will work)
What is the time-frame of anthrax sx?
- incubation period of 2-60d
- symptom initiation to death as short as 3d
How is anthrax used as a weapon?
most likely aerosolized

- spreads centrifugally and uniformly
- scabs contain the virus
- starts in mouth and on palms
What do we do to treat smallpox?
- ACAM2000 (bifurcated needle,
- in SNS stock only)
- Vaccine ImmunoGlobulin (VIG)
- CI in pregnancy
- supportive care (nutrition, fluids, eye care)
- Imvamune (in Phase III now)
What is the mortality rate for smallpox?
What is the time-frame for smallpox sx?
7-17d incubation period
Is plague contagious?
What is the key identifier of plague?
swollen lymph nodes or "bubo" (bubonic type)
What is the treatment of plague?
- STILL TREAT PREGNANT
What is the mortality rate for plague?
