HIV/AIDS is a leading cause of disease burden in sub-Saharan Africa. Existing evidence has demonstrated that there is substantial local variation in the prevalence of HIV; however, subnational variation has not been investigated at a high spatial resolution across the continent. Here we explore within-country variation at a 5 × 5-km resolution in sub-Saharan Africa by estimating the prevalence of HIV among adults (aged 15–49 years) and the corresponding number of people living with HIV from 2000 to 2017.
Programmatic mapping to determine the size and dynamics of sex work and injecting drug use in Mauritius
HIV in Mauritius is in a concentrated phase. Most HIV infection is among key populations (KPs) including female sex workers (FSW), people who inject drugs (PWID), men who have sex with men (MSM), and transgender sex workers (TGSW). The objective of this research was to use geographical mapping to determine the precise locations, typologies and population estimates of each KP in Mauritius. From May to July 2014 a programmatic mapping approach determined national estimates and information on the specific locations, “hotspots”, frequented by KPs in Mauritius.
For the first time since the HIV epidemic began a little over three decades ago, we finally have the tools that could allow us to achieve an AIDS-free generation within the next 15 years. More than any other epidemic in recent memory, HIV/AIDS has exacted a terrible toll on humankind. Since 1981, more than 75 million people have been infected with HIV with more than half of these are already dead from AIDS-related complications.
