Unnatural Outbreak Bioterrorism = the deliberate use of an infectious disease to cause an epidemic for political or religious reasons Leads to fear, anxiety, panic, depression, economic damage Flash mob as analogy for bioterrorism Portent – you know something is happening or that there is a crisis, but you are unsure exactly what it is Some left early (escaped) “critical mass” – at some point it kind of takes over everything, once there are enough cases (dancers) Dynamic changed (musically in the video) – disease may mutate or be genetically manipulated Public place, large numbers Exponential number of cases (dancers) Irrespective of age New focus – disease (or dance) suddenly breaks into a new group of the population Known symptoms (dance moves) Familiar disease (song) Caught some people by surprise Hypochondria – some people think they have disease but they really don’t (some people danced along even though they weren’t part of the mob) Planned, attention to detail Media coverage Got everyone’s attention Suitability of biological agents for use as bioweapons Infective, virulent, transmissible, stable (can’t be easily inactivated or killed) CDC categories: (don’t memorize example disease, just characteristics of categories) Category A Agents High priority agents posing a risk to national security Easily disseminated or transmitted from person to person High mortality rates Requires special action for public health preparedness Ex: anthrax, botulism, plague, smallpox, tularemia, viral hemorrhagic fevers Category B Agents Moderately easy to disseminate Moderate morbidity rates (how many get sick), low mortality rates Require specific diagnostic capacity & surveillance Ex: brucellosis, clostridium perfringens toxin, gastroenteritis, glanders, melioidosis, psittacosis, Q fever, ricin, staphylococcal enterotoxin, typhus, viral encephalitis, water safety threats Category C Agents Emerging pathogens that may be genetically engineered Easily produced and disseminated Potential for high morbidity and mortality rates Ex: nipah virus, hantavirus Dissemination Airborne Plague, anthrax, tularemia Food and water Salmonella, shigella, E. coli (hemorrhagic form), cholera, cryptosporidium Person-to-person Ebola, plague, smallpox Preparation – see slides for more information National response – inform, fund, heavy measures (i.e. martial law), legislate, federal agencies (CDC, homeland security) Healthcare response – inform government about abnormal incidence, universal precautions, placement (inc. quarantine) & treatment of patients (and corpses) Community response – inform, monitor community health issues & challenges, secure communication lines for information, educate & empower citizens beforehand, liaison between state, federal & health organizations Individual response – prepare, plan, stay informed, 72-hour kit
