PRIMARY outcome

Timeframe: 9 weeks

Population: Participants collected at least one swab on each study arm

24 percentage of swabs with HSV detected
3 percentage of swabs with HSV detected
Frequency of HSV-2 Total Shedding From the Genital Tract as Measured by PCR, Calculated Using a Per-day Shedding Rate in Participants Treated With Suppressive Acyclovir as Compared to no Medication in HIV Seronegative and HIV Seropositive Individuals.
HIV seropositive
15 percentage of swabs with HSV detected
7 percentage of swabs with HSV detected

SECONDARY outcome

Timeframe: 9 weeks

Population: The number of swabs with HSV detected was analyzed. This is a subset of overall numbers of swabs collected, since not all swabs had HSV detected.

Median quantity of HSV detected, among swabs with any HSV detected

SECONDARY outcome

Timeframe: 9 weeks

Population: The number of participants analyzed is the same as the overall number. No participants were excluded from this analysis.
