Despite these goals, a recent review of the state of HIV concluded that the world is not on track to end the HIV epidemic 8. This article examines geographic and sub-population differences in HIV prevalence trends among young people from three rounds of the Zambia Demographic and Health Surveys —2,and — The vast majority of people living with HIV are in low- and middle-income countries.

Agnew-Brune and colleagues also reported on women who exchange sex from this study, evaluating the potential role of violence in driving HIV acquisition and risk Abstract Panneer and colleagues used US national data and found that clusters were more likely to grow when at least 1 member was not virally suppressed, although even clusters in which all persons were virally suppressed grew, suggesting individuals outside of the known cluster were likely contributing to onward transmission. For discordant results, specimens were retested using the two tests. African American women made up the majority of new diagnoses in the 3 types of communities. In the nearly four decades since HIV was first recognized, scientific breakthroughs have transformed the once invariably fatal illness to one that can be successfully managed with lifelong anti-retroviral therapy ART 3. The study examined geographical and sub-population differences in HIV prevalence trends among young people aged 15—24 years in Zambia. In urban areas, HIV prevalence among women declined from New global efforts have been mounted to address the epidemic, particularly in the last decade. Zambia is one of 15 countries in the world that have the highest HIV disease burden. Although previous studies have examined subnational variation in HIV prevalence in select countries 11 , 12 , 13 , 14 , 15 , 16 , 17 , 18 , 19 Supplementary Table 1 , there is—to our knowledge—no comprehensive and comparable set of subnational HIV prevalence estimates for all of sub-Saharan Africa.

No substantial differences in sexual behaviors were observed over time. Stephenson and colleagues evaluated a new assay measuring antibody epitope signatures to determine recency of infection Abstract Progress also has been made in preventing mother-to-child transmission of HIV and keeping mothers alive.

These estimates highlight substantial differences between and within countries in levels and trends in HIV prevalence and the spatial concentration of people living with HIV.
