The consequence of failure of our antiretroviral and PMTCT programme is too ghastly to contemplate…

HIV/AIDS Curriculum Integration:
Student Design: Tensional Integrity
Challenges: Thematic Areas
Recommendations: Disability
- Disability lens reflects chronicity of HIV
- Policy implementation effective only with established financial structures
Sensitization of clinical staff
- Access to health care; education; rehabilitation for disabilities
Recommendations: Fertility and HIV www.hartcapetown.co.za (Affordable and holistic approach for HIV +ve couples wanting to reproduce)
Guided by policy and best practice “It’s not the HIV that’s killing me… my mother in law will say where is the baby?”: A qualitative study of couples facing HIV and infertility. (Cal Volks, 2012).
- Reproductive health fertility specialist to consult on draft guidelines with HIV specialists on this population
- Call is for more consistent policy and full funding (not partially subsided)
- Because partial funding discriminates against the right of HIV+ couples to reproduce
Review of international guidelines (Mmeje)
Informing policy decisions and client care
Recommendations: Technology for Behaviour Change
Policy Regulations: Emphasising protection of respondents in digital media (recognising future implications) “How informed is informed consent?”
Cellphone technology and other mechanisms for treatment adherence and encouragement (V. Nembaware)
Links biomedical and psychosocial
“Umhlobo Wami” (V. Nembaware)
Recommendations: Rights and Violations PLHIV
UNAIDS toolkit: Defines risk, harm, defences. “Disclosure as a defence” (seen as informed consent to limit risk)
Sensitization (Maseko)
Judiciary and police need education in HIV litigation (Anonyuo)
Recommendations: HIV Prevention
Prevention strategies which interact with social and cultural dynamics
Short term:
education, communication and sensitization strategies at multiple level (individual, community and systems)
Medium term:
further research to inform policy
Long term:
embedded into policy and programming
Possible Areas of Inquiry
- How do we remain reflective about the language of “Key Populations” to notexclude vulnerable individuals and groups that we may have lost sight of?
- Considering the emerging focus of cash as an incentive, for behaviour change – is there a distinction between good and bad transactionality?
- Fear of the loss or injury to manhood emerged as a significant barrier to VMMC programmes; how can social research help us understand the relationship between circumcision, masculinity and HIV prevention?
- If the focus is on health of marginal groups (SW, MSM and drug users) whose legal situation is precarious, and there are limited efforts to decriminalise their activities, are we really addressing the primary drivers of their vulnerability?
- Stigma is a structural driver of HIV – guidance is needed at a national level toovercome this. How can we formulate a national strategy in response to this?
Track E

- SMLTA mentorship model applied in Zimbabwe (Simbi, 2013)
- Dalmeida (2013) suggested the promotion and scale up of Open Polyvalent Platforms should be considered for resource limited settings
Cost Effective Measures – Recommendations
- Haacker (2013) Analysis in 2010 indicates that one MMC results in about 0.2 HIV infections averted for males up to age of 20
Highlights the importance of targeting young males
- Kripke (2012) Review of the KwaZulu – Natal DOH programme implementation
Scale up of VMMC was suggested as cost effective prevention response coupled with condom promotion.
Cost Effective Measures – Recommendations
- Maselle (2013) Evaluation of Pharmacy Only Visits (POV) Programme in Uganda
Focus on enhancing POV to assist with task shifting
- El-Sadr (2013) Analysis of routine data of patients enrolled in care
By assessing eligibility for initiation of ART, patients can be placed faster on treatment as well as initiation of healthier patients on ART
