CoRECT will help identify the important components of a data-sharing partnership between health departments and HIV care providers, and determine the extent to which a health department intervention can increase the number of HIV-infected persons out-of-care who: (a) link to an HIV clinic; (b) remain in HIV medical care; (c) achieve HIV viral load suppression within 12 months; and (d) achieve durable HIV viral load suppression over 18 months. We will also measure the cost-effectiveness of this intervention in regards to improved health in the individuals (re)-engaged in HIV care and reductions in further HIV transmission in the community.
