A total of 6,519 commercial sex workers (CSW) and 2,242 sexually promiscuous persons (SPP) and 19,045 STD clinic attendees were screened between July 1987 and July 2002. All the blood samples were tested by ELISA for HIV. The ELISA reactive subjects were further tested for confirmation by Western Blot. Of STD clinic attendees 149 (0.78%), of CSW 247 (3.78%) and of SPP 637 (28.4%) were confirmed HIV sero-positive. Sampling age group was 15-45 years. Maximum screened were between 22-40 years. Our study revealed higher prevalence of HIV among the SPP followed by CSW and among the patients attending STD clinics in Kolkata. Infection appears to be remarkable in the age group 22-40 years.
