It has been thirty years since the first case of HIV/AIDS was identified. The United Nations Program on HIV/AIDS (UNAIDS) has established a framework as a goal for drastically reducing new AIDS infections. The 90–90–90 framework, as it is known, consists of the following goals: 90% of people with HIV know their status, 90% of those diagnosed receive antiretroviral therapy (ART), and 90% of those who receive ART have undetectable levels of the virus, all by 2020. In sub-Saharan Africa, the current percetages are 81–66–52, and there were 1.8 million people newly infected in 2017, so there is still much work to be done. There will be a special issue of the International Journal of Environmental Research and Public Health containing research papers that focus on interventions to prevent HIV. Manuscripts may be submitted at www.mdpi.com and will subsequently be peer-reviewed. Associate Professor Richard Wamai will be the sole editor of this special issue due out 2019.
