Answer

In 2016, the reported rate of AIDS diagnoses in the United States was 5.6 per 100,000 population. [72] From 1981-2016, 1,232,346 persons were diagnosed with AIDS in the United States, and 692,789 people had died with AIDS by the end of 2015 (although reporting limitations mean that not every "death with AIDS" is directly attributable to AIDS itself).

US rates vary by state. See the latest CDC surveillance report for full details.

The overall figures may give a false impression that the HIV epidemic is relatively homogeneous. In fact, the HIV epidemic is best viewed as numerous separate epidemics among distinct risk groups, although the various epidemics clearly have some level of overlap. In any given area, the infection may be most prevalent among users of intravenous drugs who share needles. In another, the main risk group may be men who have sex with other men. And in yet another, the main risk group may be female sex workers.

These sub-epidemics each follow their own pattern, although there is some degree of interdependence. Early on, nearly all cases of HIV infection detected in the Western Hemisphere were in homosexual men, but the spread of the disease to female partners of bisexual men with HIV infection gave rise to an increased rate among heterosexual persons.
