Epidemiologic Strategies for Detection of Exposures and Outbreaks

  • A rapid increase in disease incidence
  • A marked increase in people seeking care, especially with fever, respiratory, or gastrointestinal symptoms
  • An endemic disease occurring in an unusual pattern and at an uncharacteristic time
  • Higher rate of cases among people who had been outdoors
  • Clusters of patients arriving from a single location or area
  • Large number of rapidly fatal cases
  • Any patient presenting with an uncommon disease

CDC Category A bio-agents: (highest priority)
  • Easily disseminated or transmitted
  • Result in high mortality rates
  • Potential for major public health impact
CDC Category B bio-agents: (second highest priority agents)
  • Moderately easy to disseminate
  • Result in moderate morbidity and low mortality
  • Require CDC's diagnostic capacity and enhanced disease surveillance
CDC Category C bio-agents: (third highest priority agents)
Emerging pathogens that could be engineered for mass dissemination because of:
  • Availability
  • Ease of production and dissemination
  • Potential for high morbidity and mortality and major health impact
