New HIV infections have fallen far below their peak
Estimated new HIV infections worldwide each year
Data: Our World in Data, based on the WHO Global Health Observatory
New HIV infections climbed through the epidemic's early years to a peak of 3,400,000 in a single year, 1996, as the virus outran the world's response. That is the high-water mark of one of the deadliest epidemics in modern history.
The key rows
Since then, prevention, testing, and treatment that makes a suppressed person unable to transmit the virus have brought new infections down every year, to 1,300,000 in 2024. That is real progress, and it is still far above the target of ending AIDS as a public-health threat. The decline has also been slower than for AIDS deaths, so prevention remains the harder half of the fight.
Asked often
Are new HIV infections falling?
Yes. New HIV infections fell from a peak of 3,400,000 in 1996 to 1,300,000 in 2024, though the decline has been slower than the fall in AIDS deaths.
Why do new infections matter alongside deaths?
Deaths have fallen faster than new infections because treatment keeps people alive. Driving down new infections is the harder task, and the one that will actually end the epidemic.
