However, a variety of studies suggest that human immunodeficiency virus (HIV) infection in prostitutes follows a different pattern than that for STDs: HIV infection in non-drug using prostitutes tends to be low or absent, implying that sexual activity alone does not place them at high risk, while prostitutes who use intravenous drugs are far more likely to be infected with HIV. Emerging data from heterosexual groups similarly suggest a low rate of heterosexual transmission, particularly from women to men. Prostitutes who do not use intravenous drugs probably face their highest risk from steady partners who may be infected with HIV and other STDs and with whom barrier protection is generally not used.
Therefore it's the drug use that's hte HIV issue more than the prostitution itself.
I've been looking for sources too, while you were. I found this:
WHO | Sexually Transmitted Diseases
It broadly talks about HIV infection in different geological locations.
Sub-saharan Africa: Highest infection rates are found among commercial sex workers, truck drivers and seasonal migrant workers.
Asia and the Pacific: Increasing sex trade, use of illicit drugs, and rates of sexually transmitted infections contribute to an increased vulnerability in the region. Injection drug use and heterosexual intercourse are the primary modes of transmission, ... (my emphasis)
Latin America and the Carribean: While in some countries HIV infections remain concentrated mainly in men who have sex with men and injecting drug users, others are experiencing increasing rates of heterosexual transmission.
Eastern Eurpoean: most of which occur among injecting drug users.
