Centers for Disease Control and Prevention (CDC) 18-1805: De-duplication of Case Pairs in the National HIV Surveillance System Using the Black Box

This CDC project supports public health jurisdictions who conduct HIV surveillance and prevention activities.  The Georgetown ATraTM infrastructure provides the ability to rapidly exchange data on persons with HIV in an environment that meets the highest security and confidentiality guidelines.  This project builds on previous work done with DC, MD, and VA as an NIH pilot and a CDC pilot with 8 jurisdictions along the East Coast.

This exchange improves the timeliness, completeness, and accuracy of local and national HIV surveillance data that is utilized for assessing progress on key health outcomes for persons with HIV and national indicators for the Ending the HIV Epidemic initiative.

Currently, 38 jurisdictions (see map) have signed data sharing agreements with Georgetown and participate in de-duplication activities.
