The goals of the United States' National HIV/AIDS Strategy are reducing HIV infections, increasing linkage to care, and reducing health disparities. To accomplish these, it is imperative to have accurate data about HIV prevalence, especially in high-burden populations, including immigrants, ethnic/racial minorities and other minority populations. However, recent increases in HIV prevalence among Black migrants from sub-Saharan Africa has drawn attention to the need to examine the epidemiological diversity of the Black population, and accurately account for HIV prevalence within it. In most HIV surveillance data, a single category, Black/African American, is used to combine data for U.S.-born and foreign-born Blacks, including migrants from sub-Saharan Africa. Such categorizations result in under-estimation of HIV prevalence in the African immigrant population, making it difficult to allocate resources appropriately for HIV prevention and treatment. This paper highlights and provides recommendations regarding the importance of disaggregating HIV surveillance data on Blacks by country of birth.
