Placing Bioterrorism in its Context Dr. C. de Ville de Goyet
The Anthrax great scare A demonstration of the superiority of informal reporting systemsA demonstration of the superiority of informal reporting systems Six deaths: A society overwhelmed with fearSix deaths: A society overwhelmed with fear Not a new threat!Not a new threat!
Anthrax Threats Reported to FBI Source: M. Lyons, CDC from FBI personal communication to Dr. Eric Noji
A critical look at some slides from CDC Most of the slides used are from Dr. Eric Noji Presentation at the PAHO Senior Managers Meetings in Nov Those slides have a blue background
Detection & surveillance Rapid laboratory diagnosis Epidemiologic investigations Implementation of control measures Public Health Response to… Bio-terrorism
Public Health Role in “Bioterrorism” “Detect and control the epidemic” Comments: Is it not the normal role of the Ministry of Health? Can you detect terrorist outbreaks without detecting first normal epidemics?
Early, rapid recognition of unusual clinical syndromes or deaths & of increase above “expected levels” of common syndromes, diseases, or death Rapid etiologic diagnosis Rapid response Bioterrorism Surveillance
Key features –Real time data real time epidemiology –Syndrome-based reporting –Sentinel surveillance sites –Pro-active (high profile potential target events, ongoing surveillance in sentinel sites) –Reactive (monitoring and response) –Aberration Detection
Syndrome Surveillance The monitoring of illnesses based upon a constellation of symptoms and/or findings Provides an “early warning system” for outbreaks, emerging pathogens
Likely BT Agents: Initial Symptoms Agents –Anthrax –Plague –Q-fever –Tularemia –Smallpox Initial Symptoms –Fever –Cough –Malaise –Headache
Current Challenges Identification of localized clusters Sustainability of surveillance system Development of response protocols
Unanswered Questions What is the threshold that initiates response What is the sensitivity and specificity of surveillance systems Usefulness and feasibility of aggregate data from hospital admissions, ICD-9 codes on a large scale Do we have an answer to these questions for normal surveillance?
