Global Disease Detection Operations Center - What We Do

To address weaknesses or gaps in global public health surveillance and response capacity, the Global Disease Detection Operations Center, modeled on WHO’s Alert and Response Operations and established in early 2007, serves as CDC’s platform dedicated to detecting and monitoring global public health events of international importance using event-based surveillance.

The GDD Operations Center monitors outbreaks from infectious and non-infectious causes including public health events attributable to disasters, intoxications, and chemical, radiological or nuclear releases, to identify new or unexplained global public health threats and better position CDC to respond. Zoonotic disease outbreaks among animals come under surveillance to assess signals of emerging or re-emerging outbreaks of human disease.

GDD Operations Center supports two agency-wide functions:

  • Global risk- and event-based surveillance and
  • Operational and financial support for a subset of CDC's international deployments in response to events for which international assistance has been requested.

The GDD Operations Center detects and supports the investigation of outbreaks at the earliest stages, often before the cause is determined. Several investigations, e.g., Nodding Syndrome in Africa, Chronic Kidney Disease in Central America, are ongoing as the etiology has yet to be determined.    

Since 2007, the GDD Operations Center monitored and reported over 1300 unique outbreaks of more than 140 diseases occurring in over 150 different countries. The GDD Operations Center's outbreak response contingency fund provides financial support to CDC programs that makes possible a prompt response to international requests for CDC field assistance.
