 AB    In order to describe the changing patterns of risk factors for HIV-1
       transmission of patients using hospital services at an AIDS referral
       centre in Porto Alegre, southern Brazil, data on demographic
       characteristics, referral patterns and risk factors at time of first
       presentation were collected prospectively on 405 patients between
       October 1985 and September 1991. Overall HIV-related patient workload
       increased during the study period, as did the proportion of infected
       female patients seen (P < 0.05). Of all patients, 147 (36%) presented
       with symptomatic HIV disease and 77 (19%) presented with an AIDS
       defining condition; men were more likely to present with symptomatic
       disease than women. Approximately 156 (44%) of men were self-referred
       compared with 4 (8%) of the women (P < 0.0001). Of the 357 infected men,
       82 (23%) were bisexuals; of the 26 heterosexually infected women, 7
       (24%) had bisexual male partners. These data suggest the increasing
       importance of heterosexual HIV transmission in this hitherto 'low'
       prevalence area, with male bisexuals constituting an important route
       through which heterosexual females are being infected in this area. The
       data also suggest that heterosexual women in Southern Brazil do not
       perceive themselves to be at risk for HIV-1 infection.
