Outcome Measures

Primary Outcomes (2)

  • Within-subject Genital HSV Mucocutaneous Shedding Rate

    Subjects were assessed for within-subject genital HSV mucocutaneous shedding rate, as calculated by the number of HSV-positive swabs per subject relative to the total number of swabs collected per subject. The swab test detects the presence of herpes virus DNA. A swab was regarded as positive for HSV-DNA if at least 3 HSV genome copies were detected by quantitative PCR per reaction (equaling 150 copies per mL of swab collection medium). When multiple swabs were available from the same time point (e.g., genital and lesional swab), the swab with the highest copy number was retained for computation of the shedding rate.

    28 days

  • Overall Shedding Rate

    Subjects were assessed for overall shedding rate as the total number of HSV-positive swabs per treatment group divided by the number of swabs collected per treatment group.
