A prospective cohort study of partner testing for herpes simplex virus and sexual behavior during pregnancy.

BACKGROUND: We investigated whether serotesting sexual partners of pregnant women for herpes simplex virus (HSV) improves adherence to safer-sex practices. METHODS: A total of 287 HSV-2-seronegative pregnant women were recruited, and their partners were invited for HSV serologic testing. On the basis of test results, women were placed into 4 groups: those at risk for HSV-2 infection, those at risk for HSV-1 infection, those whose partner was not tested, and those not at risk for HSV infection. Women received safer-sex counseling and completed diaries of sexual activity. RESULTS: Women in HSV-2-serodiscordant couples (ie, those in relationships in which they were at risk for HSV-2 acquisition) reported a smaller percentage of days with unprotected genital sex acts as compared to women who were not at risk (2% vs 8%; relative risk [RR], 0.3 [95% confidence interval {CI}, .1-.8]; P = .002) and to women whose partners' HSV status was unknown (2% vs 11%; RR, 0.2 [95% CI, .1-.8]; P = .02). Women in HSV-1-serodiscordant couples showed no difference in the frequency of genital sex acts, unprotected genital sex acts, or oral sex acts as compared to those not at risk and to those whose partners' status was unknown. CONCLUSIONS: Pregnant women at known risk of HSV-2 acquisition by partner serotesting were less likely to engage in unprotected genital sex acts than HSV-2-seronegative women with partners who were negative or not tested.

The acceptance of HSV-testing partners of HSV-2 seronegative pregnant women.

OBJECTIVES: To estimate the acceptance of HSV testing partners of HSV seronegative pregnant women and identify associated factors. STUDY DESIGN: Consecutive women identified as HSV-2 seronegative during routine testing in pregnancy were asked to invite their partners for HSV testing to identify serodiscordance. Logistic regression identified factors associated with partner testing. RESULTS: Between 2001 to 2006, 315 women enrolled (28% of those approached) and 242 (77%) partners were tested. Married couples were most likely to be tested [adjusted odds ratio (aOR) 7.72, 95% CI: 2.47-24.15]. Partners of black women (aOR 0.17, 95% CI: 0.04-0.71), and those with at least a college degree (aOR 0.43, 95% CI: 0.19-0.98) were less likely to be tested. CONCLUSIONS: In this population, partner testing among HSV-2 seronegative women was feasible which supports further study to determine if identification of partners who pose a potential risk of HSV infection during pregnancy is an effective approach to reduce HSV acquisition in pregnant women.
