Abstract

We studied the association between herpes simplex virus type-2 (HSV-2) and HIV-1 viralload in plasma, semen, cervico-vaginal secretions and genital ulcers. Forty-seven (68%) men and 57 (80%) women were HSV-2 antibody positive, of whom 12 (26%, 95% confidence interval [CI] 20, 32) and five (8%, 95% CI 4, 12), respectively, had HSV-2 genital shedding detected by polymerase chain reaction. The mean HIV-1 seminal and cervico-vaginal viral loads did not differ significantly according to the presence of HSV-2 shedding. Eleven men and 15 women presented with genital ulcers; all ulcers were due to HSV-2. Ten men and nine women were followed up over six days: the mean (95% CI) HIV-1 log viral load copies/mL in the genital ulcers at baseline and final visits were 2.5 (2.3, 2.7) and 3.1 (2.0, 4.2) for men and 3.0 (2.6, 3.4) and 2.7 (2.3, 3.1) for women. These findings do not support the hypothesis that HSV-2 increases the HIV-1 viral load in genital secretions.
