CDC is working with state and local health departments
and information system contractors to develop real-time special event syndromic
surveillance and analytical methods. During special events, CDC Enhanced
Surveillance Projects (ESP) monitor sentinel hospital emergency department
visit data to establish syndrome baseline and threshold. Aberration detection
models developed and analyzed at CDC identify deviations in visit data and
report to state and local health departments for confirmation and appropriate
epidemiological follow-up. ESP has been tested at the World Trade Organization
Ministerial in Seattle, the Republican and Democratic National Conventions
held in Philadelphia and Los Angeles, respectively, and the Super
Bowl/Gasparilla Festival in Tampa, Florida. CDC will continue development
and evaluation of ESP, in order to provide guidance and resources to state
and local health departments for implementation of local real-time surveillance
systems.
