SUMMARY Trichomonas vaginalis has long been recognized as one of the most prevalent sexually transmitted infections. However, it is only in recent years that it has been appreciated that Trichomonas may play a critical role in amplifying human immunodeficiency virus (HIV) transmission. Given the evidence that T. vaginalis likely promotes HIV infection, the apparent high level of Trichomonas infection in the African-American community is cause for concern. Even if T. vaginalis increases the risk of HIV transmission by a small or modest amount, it translates into a sizable population effect since Trichomonas is so common in this community. Therefore, control of trichomoniasis may represent an important avenue of control for the prevention of HIV transmission, particularly among African-Americans.

Providers should maintain a high index of suspicion for NS among patients with syphilis, particularly those with HIV infection.

Rapid HIV testing allows same-day results, increasing the number of persons who learn their HIV status. Understanding how clients in different settings perceive rapid testing may increase acceptance of this technology. From June 1999 to August 2001 we interviewed 256 clients at a publicly funded urban sexually transmitted disease (STD) clinic and 1201 clients at a community- based HIV counseling, testing, and referral center (Los Angeles Gay and Lesbian Center; LAGLC) about their posttest satisfaction with rapid HIV testing. HIV prevalence was 3.9% at the STD clinic and 5.3% at the LAGLC. In multivariate analysis, adjusting for age, sexual orientation, race/ethnicity, history of STDs, self-perceived HIV risk, prior HIV test and HIV testing results, clients at the STD clinics (versus LAGLC) were more likely to find testing stressful (adjusted odds ratio [AOR]: 1.75, 95% confidence limits [CL]: 1.27, 2.42) and feel that they received their results too quickly (AOR: 2.05, 95% CL: 1.39, 3.03). Latinos (versus whites) were more likely to report that they received their results too quickly (AOR: 4.99, 95% CL: 3.48, 7.14) and that it would be better to wait a week for HIV test results (AOR: 2.48, 95% CL: 1.51, 4.09). Further research may elucidate the reasons why some groups prefer to wait for results, and enable policymakers to better design strategies to reach high-risk groups with rapid HIV testing.

Effective sexually transmitted disease risk reduction interventions using the Internet are needed to reach Internet-using, sex-seeking MSM populations engaging in high-risk behaviors.
