  • natural outbreak
  • accidental release
  • biocrime
  • bioterrorism
  • biowarfare
17
Q

in the spectrum of biorisks there is a focus on a need for:

A

rapid pathogen identification tracing

18
Q

importance of rapid pathogen identification tracing

A
  • accidental or natural infection
  • identification of microbes
  • bioterrorism
19
Q

example of rapid pathogen identification tracing

A
  • nurse exposed to HIV while handling a patients blood
  • tested on the day of injury - anti-HIV antibodies
  • employers - you were already infected
  • nurse - no sex, no needles, no transfusion
  • virus profiles analyzed from both the nurse & patients

Q

example of food poisoning

A
  • intentional by Rajneeshees cult in an attempt to influence an election
  • obtained Salmonella through state-license medical laboratory
  • coated plastic gloves, then handled salad bar food
  • deliberate act but originally dismissed
21
Q

how did they know the food poising example was deliberate

A
  • 16 cases in the past 3 years, only 8 Salmonella
  • 2 waves of poisoning
  • so many people got it in a small area

22
Q

what circumstances should cause public health officials to investigate an outbreak to suspect that the outbreak is intentional?
