T Creek, personal communication 2008 Impact of Incident HIV Infection in Pregnancy A study in Botswana showed: Among women testing negative in early pregnancy: Botswana National PMTCT program transmission data show: Extrapolating incident HIV to the national Botswana figures : Incident HIV is thus estimated to account for 470/1090 (43%) of all infant infections in 2007 1.3% were infected in 17 weeks before delivery 1.8% were infected in the first year after delivery 13,900 HIV+ women infected estimated 620 infants (4.7%) Estimate 950 women acquired HIV during pregnancy or first postpartum year, and infected 470 infants

NEW SLIDE - CAN WE MAKE THIS SLIDE MORE ATTRACTIVE
Emphasize all babies breast fed and transmission related to breast feeding alone.
Africa also has a disproportionate share of the world ’s doctors All you have to do is go to a hospital in London to see why.
… we must seek innovative ways of harnessing and focusing both the financial and the human resources that already exist…
Goal 1. PMTCT Prevent babies from contracting HIV through mother-to-child transmission Goal 2. Healthy mothers and infants Keep mothers and babies living with HIV/AIDS alive and healthy by increasing their access to health-sustaining medical care Goal 3. Empowerment Empower mothers living with HIV/AIDS, enabling them to fight stigma in their communities and to live positive and productive lives
Training both for providing client services, but also for educating and developing the capacity of our staff and providing them the foundations in professional skills.

Background Two Cross-Sectional surveys of women attending antenatal and post delivery care at three facilities in Pietermaritzburg, South Africa – before m2m introduced and one year later, after m2m introduced. Program analysis: 345 HIV+ pregnant women and 350 HIV+ post-partum women – and these were divided into program participants and non-participants. Interviews ascertained self reported behaviors and knowledge about PMTCT among women who had received m2m services more than 2 times (participants) or had no contact. >50% of HIV+ women attending services, during antenatal care or after delivery, had received services from m2m . Results Post-partum women on average received m2m services 6 times over the course of ante and post-natal period. Findings among postpartum program participants significantly better than among non-participants (bivariate analysis).
