Brief summary: This study will test the effectiveness of a behavioral intervention to increase Prevention of Mother-to-Child Transmission of HIV (PMTCT) protocol uptake among South African HIV positive pregnant women. This study will also determine whether the participation of male partners will have additional positive impact on PMTCT uptake. The intervention will utilize a combination of both gender-concordant groups and individual or couples counseling strategies, before and after birth. During antenatal care, the intervention will use a gender-concordant group format to address PMTCT information, HIV disclosure, coping with stigma, intimate partner violence, and adherence to the overall PMTCT protocol. Just prior to birth and following birth, the intervention will shift to individual or couples-based counseling, targeting medication adherence, safer infant feeding, and family planning. It is hypothesized that women attending the intervention will be more likely to properly take HIV medication before birth and provide it to their infants. Additionally, it is hypothesized that male partner involvement will further increase the likelihood that mothers will take their HIV medication as prescribed and provide it to their infants.

Detailed description: Abstract. In rural South Africa, only two-thirds of HIV+ pregnant women seeking antenatal care at community health centers took full advantage of available "prevention of mother-to-child transmission" (PMTCT) services in 2010 (SADOH). While engagement of male partners has been encouraged as a potential means of increasing PMTCT uptake, men have been reluctant to accompany their wives/partners to antenatal care.

Recent studies generally support male involvement in promoting PMTCT, but the nature and impact of that involvement is unclear and untested. It is also clear that factors such as stigma, disclosure and intimate partner violence pose significant barriers to PMTCT uptake and retention in care, suggesting that male involvement may be "necessary, but not sufficient" to accomplish the WHO goal of \<5% infant HIV incidence. Additional measures may be needed to increase participation by HIV positive pregnant women in PMTCT.

In 2011, Mpumalanga Province had the highest rates of HIV in the country (36.7%) and rates of infant HIV incidence in rural clinics ranged up to 50%. Rates of PMTCT uptake in the Province have been among the lowest in South Africa (69%). This application proposes to expand on a successful PEPFAR- supported, PMTCT couples intervention pilot study conducted in Mpumalanga Province, ("Vikela Umndeni: Protect Your Family") to include a more representative population of HIV positive pregnant women and their partners, the primary objective being to determine whether male partner involvement plus a behavioral intervention would significantly reduce infant HIV incidence by increasing levels of adherence to ARV/ PMTCT protocols, including breastfeeding and family planning, during the antenatal and post-natal periods.

The proposed study will enroll two cohorts of HIV positive pregnant women recruited from 12 randomly assigned Community Health Centers (6 experimental, 6 control): a) Women attending without their male partners (n = 720), followed by b) Women attending with their male partners (n = 720 couples), to determine whether the influence of male participation itself or combined with a behavioral PMTCT intervention can significantly reduce infant HIV infection ante-, peri- and post-natally. It is our intention to significantly increase PMTCT participation from current levels (69%) in Mpumalanga Province to 90-95% through engaging women and couples in a unique, controlled, six session ante- and post-natal risk-reducing/PMTCT promotion intervention addressing the barriers to PMTCT (e.g., stigma, disclosure, intimate partner violence, communication, infant feeding practices, safer conception) that prevent women and men from taking full advantage of the treatment opportunities available to them and their infants. Based upon the encouraging preliminary results from our pilot study, successful CHC adoption of the "Vikela Umndeni: Protect Your Family" program could have major public health policy implications for containing the epidemic among the most vulnerable populations in rural South Africa: HIV+ pregnant women and their infants.

Eligibility criteria: Inclusion Criteria:

* HIV seropositive pregnant women with partners, 20-24 weeks pregnant (typical time of entry into antenatal clinic care), aged \>18.
* In Phase 2 (couples phase), both women and their partners will be enrolled. For the purposes of this study, primary male partners are defined as 1) husband, 2) current baby's father, or 3) current sexual partner.

Exclusion Criteria:

* Persons actively psychotic (auditory or visual hallucination) or intoxicated (e.g., under the influence of alcohol of illegal drugs) will not be eligible and will be referred for treatment. Following resolution of symptoms, these persons will be eligible for the study. N.B.: Any person presenting for sessions actively psychotic or intoxicated will be referred for treatment and will not be eligible to participate in sessions until symptoms are resolved due to reduced likelihood of benefit from sessions.
