Background: To determine the prevalence of HIV-1 in two high risk populations to include men who have sex with men (MSM) and female commercial sex workers (FCSW) in Bogota.

Methods: Seroprevalence studies have been conducted in collaboration with the Colombian League for the Fight Against AIDS, the National Institute of Public Health of Colombia and NMRCD. Screening was performed with HIV-1 ELISA and confirmatory results were made by Western Blot (WB). Questionnaires were administered in an anonymous fashion. Pre and post counseling was given to every subject. The difference between both studies was the form in which the approach of subjects was made: for MSM the approach was made in their meeting places (bars and discotheques, video houses, bath houses), whereas for FCSW the approach was made in streets and in their working places.

Results: A total of 562 MSM and 170 FCSW were evaluated. The HIV-1 prevalence among MSM was found to be 18.4% and among FCSW it was 0.6%. Correlation of risk factors noted for MSM were: Sustaining sexual contacts on video houses (RR= 2.26, 95% CI, 1.05-4.87), to have a steady male partner (RR=2.3, 95% CI, 1.1-4.8), history of an STD (RR=1.63, 95% CI, 0.78-3.41), use of alcohol (RR=1.72, 95%CI, 0.87-3.40), and receiving information on HIV-AIDS (RR=0.34, 95%CI, 0.11-1.10).

Conclusions: A much higher prevalence was noted among MSM, a finding that correlates with previous data from this region. By comparison, a much lower rate was noted among heterosexually-promiscuous women. It appears that the HIV epidemic in Bogota continues to be a concentrated one, principally among homo/bisexual men.
