Description:The primary national HIV prevention goal is to reduce the annual number of HIV infections [1]. A key objective 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 (persons living with diagnosed or undiagnosed HIV infection), and (3) percentage of diagnosed infections among persons living with HIV (percentage of persons aware of their infection) are essential to determining whether prevention program efforts are reducing the annual number of HIV infections (incidence) and achieving prevention 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. The percentage of diagnosed infections among persons living with HIV reflects persons currently in need of care and treatment services for HIV infection.
To produce the HIV incidence and prevalence estimates 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).
