Success in these countries and many others has been largely due to substantial global action, policy changes and funding. Between 2002 and 2010, development assistance for health targeting HIV/AIDS increased from US$1.4 billion to US$6.8 billion an increase of 385.7% that does not include funds spent by low- and middle-income countries themselves.
Increased access to antiretrovirals has accompanied declines in incidence, and more interventions to prevent mother-to-child transmission.
"The success we have made in combatting HIV/AIDS illustrates what can happen when funders, advocates, governments and health experts commit to a common goal, and dedicate resources to back up the commitment," said Dr. Christopher Murray, IHME director and one of the study's authors. "By gathering the best evidence on the spread of HIV/AIDS we can ensure continued progress."
The study also notes the challenges in collecting country-level estimates from different sources and calls for improvements in vital registration data that records a population's births and deaths.
In sub-Saharan Africa, which accounts for 70.9% of the global health loss attributable to HIV/AIDS, progress against the disease is mixed. In Rwanda, Botswana and Zimbabwe, for example, mortality due to HIV/AIDS decreased dramatically from epidemic peak to 2010; 83.1%, 74% and 47.5% respectively. In other sub-Saharan African countries like Democratic Republic of the Congo, Angola and the Central African Republic, progress has been nearly nonexistent.
"AIDS is not just a problem in Africa," explained Dr. Rafael Lozano, IHME's Director of Latin American and Caribbean Initiatives and one of the paper's authors. "We see significant mortality numbers from AIDS in countries as varied as Venezuela, Thailand and Jamaica."
