Description:The primary goal of the initiative, Ending the HIV Epidemic: A Plan for America (EHE), is to reduce the annual number of new HIV infections by 75% in 5 years and by at least 90% in 10 years [1]. A key objec- tive to reaching this goal is to increase the percentage of persons living with HIV who are aware of their infection [2]. Persons who are aware of their HIV infection can be linked to care and receive treatment to reduce morbidity and viral load levels, making them less likely to transmit the virus to others [3]. Estimates of (1) HIV incidence, (2) prevalence (per- sons living with diagnosed or undiagnosed HIV infection), and (3) percentage of diagnosed infections among persons living with HIV (percentage of per- sons living with HIV who are aware of their infection) are essential to determining whether prevention program efforts are reducing the annual number of new HIV infections (incidence) and achieving preven- tion outcomes.
Incidence measures the number of infections during a specified time (e.g., year). These estimates can be used to assess changes in characteristics of persons most at risk for acquiring HIV infection. Diagnoses refer to persons who may have been infected years before diagnosis.
Prevalence refers to the number of persons living with HIV disease at a given time regardless of the time of infection or whether the person has received a diagnosis. Prevalence and the percentage of diag- nosed infections among persons living with HIV reflect the number of persons in need of care and treatment services for HIV infection.
To produce the HIV incidence and prevalence esti- mates in this report, we used the result of the first CD4+ T-lymphocyte (CD4) test after HIV diagnosis and an estimation method based on a CD4 depletion model (referred to hereafter as the “CD4 model”) [4– 7]. The first CD4 test results after HIV diagnosis are routinely collected by all jurisdictions as part of the National HIV Surveillance System (NHSS).
This report was prepared by the following staff and contractors of the Division of HIV/AIDS Prevention, National Center for HIV/AIDS, Viral Hepatitis, STD, and TB Prevention, CDC: Laurie Linley, Anna Satcher Johnson, Ruiguang Song, Sherry Hu, Baohua Wu, Zanetta Gant, Timothy Green, Betsy Gunnels, H. Irene Hall, Angela Hernandez, Michael Friend (editing and desktop publishing), the HIV Incidence and Case Surveillance Branch, and the Data Management Team of the Quantitative Sciences and Data Management Branch.
