Update

The number of new HIV infections globally continues to fall. Modelled estimates show that new infections (all ages) declined from a peak of 3.4 million [2.6 million–4.4 million] in 1996 to 1.8 million [1.4 million–2.4 million] in 2017—the year for which the most recent data are available. However, progress is far slower than that required to reach the 2020 target of fewer than 500 000 new HIV infections (see graph below).
