Multivariate risk factors of the female-to-male per-sex-act and per-partnership transmission probabilities of HSV-2

Cofactor Relative risk (95% CI) of the per-sex-act transmission probability Relative risk (95% CI) of the per-partnership transmission probability
Presence of HSV-2* 2.5 (1.08–6.32) P=0.036 3.03 (1.6–5.3) P< 0.001
Circumcised male 0.59 (0.36–0.91) P=0.021 0.61 (0.39–0.89) P=0.011
Reported condom protection 1.0 (0.52–1.7) P=0.98 0.49 (0.26–0.80) P=0.005

In one of the partners. If HIV is present in both partners the relative risk (RR) becomes RR2.
