Enhanced surveillance of persons with early and late HIV diagnosis to understand system and individual factors associated with new infection and delayed testing

The purpose of this NOFO is to improve understanding of barriers and gaps in HIV prevention services that may lead to continued HIV transmission or delayed diagnosis of HIV. This NOFO will support enhanced surveillance of people diagnosed with HIV during the earliest and latest stages of infection (i.e., stages 0 and 3, respectively) to understand recent experiences with HIV prevention and testing services, as well as the system- and individual-level barriers that led to these failures in early diagnosis and prevention. Recipients of this NOFO will identify, locate, and recruit all persons diagnosed in the past year with stage 0 or stage 3 infection in their jurisdiction for participation in behavioral interviews conducted by a CDC contractor. Data collected will be used to inform HIV prevention and testing activities to ultimately reduce new HIV infections and increase early diagnosis among those newly infected.
