Abstract:
Since the beginning of the HIV pandemic, almost 60 million
people have been infected with HIV and 25 million have
died from HIV-associated illnesses [1]. Sub-Saharan Africa
is the region most affected by the pandemic and is home to
68% of all people living with HIV worldwide [1]. Since 2002,
the international drive to scale up antiretroviral treatment
has gained tremendous momentum [2], and by the close
of 2009, an estimated 5.2 million persons were receiving
combination antiretroviral treatment (cART). While this
represents important progress, this still is only about 35% of
the people who are estimated in need of treatment according
to current standards of care
