Infection with HIV is increasing in non-FSWs, previously thought to be at low risk in India. Since history of sexual contact with their only sex partner was the only risk factor significantly associated with HIV infection, it is likely that these women are being infected by their spouses. This underscores the need for strengthening partner-notification strategies and counseling facilities in India.

To estimate the impact of prevalent and incident herpes simplex virus type 2 (HSV-2) infection on the acquisition of human immunodeficiency virus type 1 (HIV-1), stored serum samples from a cohort of 2732 HIV-1-seronegative patients attending 3 sexually transmitted infection clinics and 1 reproductive tract infection clinic in Pune, India, were screened for HSV-2-specific antibodies. Incident HSV-2 infection was defined serologically as "recent" if a negative result of testing for HSV-2 could be documented within the previous 6 months or "remote" if >6 months had elapsed since the last negative test result. The prevalence of HSV-2 at enrollment was 43%. The HSV-2 incidence was 11.4 cases/100 person-years, and the HIV-1 incidence was 5.8 cases/100 person-years. The adjusted hazard ratios of HIV-1 acquisition from exposure to HSV-2 infection were 1.67 for prevalent HSV-2, 1.92 for remote incident HSV-2, and 3.81 for recent incident HSV-2. Recent incident HSV-2 infection was associated with the highest risk of HIV-1 in this study, which suggests that prevention of HSV-2 infection may reduce the risk of HIV-1 acquisition.

Two hundred seventy-seven men and 25 women with a median age of 25 were evaluated. The seroprevalence of HIV was 22.2%. The etiology of GUD as determined by M-PCR was HSV (26%), H. ducreyi (23%), T. pallidum (10%), and multiple infections (7%); no etiology was identified in 34%. HIV seroprevalence was higher among those patients positive for HSV compared with other etiologies (OR = 2.1, CI: 1.2-3.7; p = 0.01). When compared with M-PCR, the Herpchek test was 68.5% sensitive and 99.5% specific. Darkfield detection for T. pallidum was 39% sensitive and 82% specific, in contrast to rapid plasma reagin and fluorescent treponemal antibody absorption test, which was 66% sensitive and 90% specific. Clinical diagnosis alone or in combination with basic laboratory tests showed poor agreement with M-PCR.

Objective-To investigate the risk factors for HIV infection in patients attending clinics for sexually transmitted diseases in India.Design-Descriptive study of HIV serology, risk behaviour, and findings on physical examination.

Same-sex and high-risk sexual behaviors are prevalent among men attending STI clinics in India. Although syphilis and GUD rates decreased, HIV prevalence remained high during the decade, highlighting the importance of additional targeted efforts to reduce HIV risk among all men, including MSM, in India.

The first estimates of the seroincidence of human immunodeficiency virus type 1 (HIV-1) and of the risk factors for seroconversion in a cohort of high-risk patients attending sexually transmitted disease (STD) clinics in India are reported. Between 1993 and 1995, 851 HIV-1-seronegative persons were evaluated prospectively every 3 months for HIV infection and biologic and behavioral characteristics. The overall incidence of HIV-1 was 10.2/100 person-years (95% confidence interval, 7.9-13.1). The incidence among commercial sex workers (CSWs) was 26.1/100 person-years, compared with 8.4 among non-CSWs. Recurrent genital ulcer disease and urethritis or cervicitis during the follow-up period were independently associated with a 7- (P < .001) and 3-fold (P = .06) increased risk of HIV-1 seroconversion, respectively. Because of the association of recurrent ulcerative and nonulcerative STDs with HIV-1 seroconversion in this setting, behavioral and biologic measures directed at the prevention and control of STDs would be expected to greatly reduce the transmission of HIV-1 infection in similar high-risk groups.
