What this is
Roughly 40 million people live with HIV worldwide. Antiretroviral therapy has turned infection into a manageable condition for most who can access it, but coverage gaps in eastern and southern Africa, among key populations, and in conflict zones keep annual mortality high. Funding for the global response has plateaued while new infections fall more slowly than targets require.
