Context
The global expansion of access to HIV treatment ranks
among the great recent achievements in public health. At the end of 2011, an
estimated 8 million people in low-and middle-income countries were receiving
ART – a 25-fold increase since 2002. Nevertheless, most low- and middle-income
countries are yet to achieve ‘Universal Access’ to ART. Reasons for this
include lack of awareness of HIV status, high cost of ART, late initiation of
ART, human rights issues affecting people living with HIV and key populations
and substantial attrition in the ‘test-treat-retain’ continuum. Addressing
structural barriers, reducing costs and strengthening the continuum of care is
critically important if the full gains of expanded HIV treatment are to be
realised.
