An Epidemiological Approach to HIV-1/2 Infection Among Female Sex Workers and Gay Men of Margarita Island
ObjectivesTo establish the prevalence of HIV-1/2 infection in both clusters; to evaluate correlations between sexual practices among gay men and HIV infection; and to evaluate the existence of female sex workers subgroups.
MethodsThe study was done in the main tourist county of the island (02-12/94). Censorships of female street sex workers and gay men were required. Two questionnaires were applied: one to evaluate characteristics of female sex workers and other to evaluate sexual practices among gay men. We collected sera of 115 female sex workers (Z=1.96 £=0.012) who were registe-red in the local hospital (RSW), 26 female street sex workers (SSW) (Z=1.96 £=0.012) and 40 gay men (Z=1.645 £=0.056). Sera samples were screened for HIV-1 and HIV-1/2 by ELISA (ABBOTT). Repeatedly reactive sera were tested by Western blot (Cambridge Biotech Corporation). Results showed that 3.6% of SSW and 25% of the gay men were HIV-1 positive. In the RSW no serum was confirmed by Western blot nor Liatek. RSW and SSW were different according to: "t" Student test for age (p=0.028017 £=0.05), Wilcoxon-Mann-Whitney test for sexual intercourse/price (p=0.000000 £=0.05) and for condom use (p=0.00008 £=0.05). We also found in the gay sample a correlation between bisexual intercourses and HIV-1 positive result using Yates X2 (p=0.0216372 £=0.05). We suggest for Margarita's AIDS control program better attention to street sex workers and non-safe sex among men, in order to reduce future chances of HIV infection to women and children of this area.
