Purpose
This study will test the hypothesis that treating HSV-2 infection in the HIV-infected partner of a heterosexual couple (meaning that one partner has HIV and the other does not) will reduce the chances that he or she will transmit the HIV virus to the uninfected partner.

Detailed Description:
This is a proof of concept study taht Suppression of Herpes Simpleax Virus Type 2 (HSV-2), the virus that cuases genital herpes, among HIV-infected persons reduces the transmission risk of passing on HIV to the HIV-uninfected partner during sexual intercourse. The Study is conducted among HIV-sero-discordant heterosexual couples in the Gabarone, Botswana region. A subset of samples will be analyzed for a study on the role of TNF-alpha in HIV-1 transmission. The goals of the substudy are to determine whether genotypic and phenotypic characteristics of HIV-1 subtypes are linked to levels of viral activation by TNF-alpha protein in virtol, whether genital viral RNA and DNA levels correlate with NF-KappaB copy number of the viral LTR and/or the viral subtype; and several other measures. Other sites include Tanzania and Kenya.
