BACKGROUND: We assessed the prevalence and risk factors for HIV-1 and HIV-2 in Lagos State (Nigeria) prostitutes. METHODS: Sera from 91 low class, 693 middle class and 101 high class prostitutes from 11 of the 12 counties of Lagos were collected. Pearson's chi-square statistic was used for comparisons of proportions, and the strength of association was evaluated by the odds ratio [OR]. RESULTS: Among high class prostitutes, HIV-1 prevalence was 9%; and sex with Asians, primarily from the Indian sub-continent [OR = 2.3, 1.7-5.4], was the main risk factor after controlling for potential confounders. HIV-1 in middle (12%) and low (18%) class prostitutes was associated with a history of genital sores [OR = 3.8, 1.4-10.4] and > 5 sex partners per day [OR = 2.5, 1.3-4.7]. HIV-2 prevalences by class were 0% in high, 2% in middle and 7% in low, and associated with non-Nigerian nationality [OR = 8, 3-11]. DISCUSSION: We hypothesize that high-class prostitutes contribute to the intercontinental spread of the HIV-1 epidemic in previously low risk areas by serving the many businessmen and drug traffickers who commute between Nigeria and India. For HIV-2, inter-country spread via overland routes, may result from truck-drivers contact with low and middle class prostitutes.
