Most countries in the region have shown an increase in life expectancy •  In South Africa, life expectancy has increased from 57 years in 2010 to 60 years

in 2012 because of ART expansion •  In an area severely infected with HIV in South Africa, life expectancy increased

by 11.3 years between 2003 and 2011, from 49.2 to 60.5 years because of ART (Bor J, et al. Science 2013)

HIV incidence among adults in eastern and southern Africa

•  HIV incidence among adults has fallen by 48% since 2001

•  Modelling studies suggest that new infections in Botswana, Namibia, South Africa and Zimbabwe are between 20 and 50% lower than it would have been in the absence of ART (UNAIDS 2012; Eaton et al. PLoSMed 2012)

Available evidence suggest that it is possible to substantially reduce HIV transmission through early provision of ART

§  Employment prospects improve for patients on ART

(Bor et al. Health Affairs, 2012)

§  People on ART have better work performances because of improved health (Rosen et al. AIDS, 2008)

§  Improved quality of life of those infected with HIV as well as their families

§  Potential to reduce stigma and discrimination

(Roura et al. STI 2009)

Challenges

•  Demand creation −  Proportion of people knowing their HIV status still low (between 10 – 75%

people ever tested for HIV across countries in the region) −  Median CD4 at first enrolment in treatment still low

•  Weak logistic management systems leading to shortage of drugs

•  Health systems and human resource capacity need to be strengthened −  to consider decentralization of care and involvement of communities to

support programmes

•  Lack of adequate treatment programmes for children living with HIV

•  The role of key populations

•  Issues related to human rights, stigma and discrimination

•  Monitoring and evaluation systems

Conclusion Hope for an AIDS free generation

•  Significant progress in scaling up ART and PMTCT services in the last decade

•  Significant reduction in mortality and morbidity •  Significant decline in new infections among children •  Decline in new infections among adults •  Improved quality of life •  Better employment prospects for people infected with HIV •  Most countries have started to implement or have plans to implement

the new WHO treatment guidelines
