Getting to zero HIV deaths: progress, challenges and ways forward
With the progressive increase in the global access to antiretroviral therapy (ART), there has been a major decline in HIV-related deaths over the past two decades. Before ART became widely available, people presenting at clinics with AIDS-defining illnesses would, on average, die within less than 1 year. Today, access to ART is widespread, with some 9.7 million people estimated to be receiving ART globally by the end of 2012. The scale up of ART has averted an estimated 4.2 million deaths in low- and middleincome countries between 2002 and 2012 and studies from high-income and low-income settings have concluded that, with timely access to ART, people living with HIV can expect a near-normal life expectancy.
