Estimated rates of sexually transmitted infection transmission in stably married couples

HSV-2Syphilis
Male infection outside of couple*19.4 (16.6 to 22.5)3.1 (2.2 to 4.2)
Female infection outside of couple*20.9 (17.9 to 24.1)1.9 (1.2 to 2.9)
Male-to-female transmission within the couple*193.3 (153.7 to 238.2)27.6 (8.1 to 60.0)
Female-to-male transmission within the couple*119.0 (89.6 to 152.3)198.8 (108.2 to 329.5)
Root-mean-squared error (RMSE)†18.12
  • *Rates are in 1000 couple-years (95% CI).

  • †RMSE is a measure of the difference between the observed and expected number of couples transitioning between different serostatuses.
