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.
