- More than 15 million individuals living with HIV are not on treatment, most of whom do not know their status. New infections—1.8 million per year—are not declining and are primarily among young adults and members of marginalized populations. Each year, the baseline, unserved population living with HIV steadily expands.
Each of the 22 million persons now on treatment will, it is hoped, live fruitfully on treatment for decades, yet at considerable cost and requiring much care to ensure unbroken continuity and evolution of services into old age.
There is still no vaccine or cure, and no hope of seeing either in the near to medium term. That fundamentally sets HIV/AIDS apart from other dangerous infectious disease epidemics. And it makes for a very uncomfortable reality when thinking about truly controlling the arc of this dangerous, infectious disease pandemic, truly sustaining the response over the long-haul, and managing the inherent risk of a rebound of the epidemic if there is not accelerated expansion of investments.
