Global life expectancy has increased by 10.2 years since 1980, with the most marked increases occurring over the past decade in Sub-Saharan Africa, where the expansion of antiretroviral therapy and prevention of mother-to-child transmission of HIV activities have expanded life expectancy by more than ten years in countries with the highest HIV burdens.
Zimbabwe in particular saw the fastest progress, with life expectancy increasing by 11.7 years in men and 17 years in women since 2005, according to the Global Burden of Disease report published in The Lancet. South Africa, Ethiopia, Botswana, Zambia, Swaziland and Malawi also saw large increases in life expectancy since 2005 due to marked reductions in deaths from HIV, the report says.
Deaths from HIV have fallen by 33 percent since the peak of global HIV deaths in 2005, when 1.8 million people died from HIV, compared to 1.2 million who died from HIV in 2015. Eighteen percent of HIV deaths were due to tuberculosis, the study authors estimate. HIV deaths among children under five have fallen by 52 percent, to 88,900 deaths in 2015.
