Abstract: Background The Millennium Declaration in 2000 brought special global attention to HIV, tuberculosis and malaria through the formulation of Millennium Development Goal 6 (MDG 6). The Global Burden of Disease 2013 study provides a consistent and comprehensive approach to disease estimation 1990 to 2013, and an opportunity to assess if there has been accelerated progress since the Millennium Declaration. Methods To estimate incidence and mortality for HIV, we used the UNAIDS Spectrum model appropriately modified based on a systematic review of the literature on mortality with and without out antiretroviral therapy (ART). For concentrated epidemics, we calibrated Spectrum models to fit vital registration data corrected for misclassification of HIV deaths. In generalized epidemics, we minimized a loss function to select epidemic curves most consistent with prevalence data and demographic data on all-cause mortality. We analyzed counterfactual scenarios for HIV to assess years of life saved through prevention of mother to child transmission (PMTCT) and anti-retroviral therapy (ART). For tuberculosis, we analyzed vital registration and verbal autopsy data to estimate mortality using cause of death ensemble modeling. We analyzed data on corrected case-notifications, expert opinions on the case-detection rate, prevalence surveys and estimated cause-specific mortality using Bayesian metaregression to generate consistent trends in all parameters. Malaria mortality and incidence were analyzed using an updated cause of death database, a systematic analysis of verbal autopsy validation studies for malaria and recent literature on incidence, drug resistance and coverage of insecticide treated bed nets. Findings Globally in 2013, there were 1.8 million new HIV infections (95% uncertainty interval 1.7 million to 2.1 million), 29.0 million prevalent HIV cases (27.9 to 31.4) and 1.3 million HIV deaths (1.2 to 1.5). At the peak of the epidemic in 2005, HIV caused 1.7 million deaths (1.6 to 1.9). Concentrated epidemics in Latin America and Eastern Europe are substantially smaller than previously estimated. Through interventions including PMTCT and ART, 19.3 million life years have been saved, 68.9% in the developing world. From 2000 to 2011, the ratio of development assistance for health for HIV to years of life saved through intervention was $4,647-$7,137 in the developing world. All-forms tuberculosis (including Individuals who are HIV-positive) incidence, prevalence and death numbers in 2013 were 6.6 million (6.4 to 6.7), 10.1 million (9.8 to 10.4) and 1.4 million (1.3 to 1.5), the same figures in Individuals who are HIV-negative were 6.1 million (6.0 to 6.3), 9.5 million (9.2 to 9.8) and 1.3 million

Background Up-to-date evidence about levels and trends in disease and injury incidence, prevalence, and years lived with disability (YLDs) is an essential input into global, regional, and national health policies. In the Global Burden of Disease Study 2013 (GBD 2013), we estimated these quantities for acute and chronic diseases and injuries for 188 countries between 1990 and 2013. Methods Estimates were calculated for disease and injury incidence, prevalence, and YLDs using GBD 2010 methods with some important refinements. Results for incidence of acute disorders and prevalence of chronic disorders are new additions to the analysis. Key improvements include expansion to the cause and sequelae list, updated systematic reviews, use of detailed injury codes, improvements to the Bayesian meta-regression method (DisMod-MR), and use of severity splits for various causes. An index of data representativeness, showing data availability, was calculated for each cause and impairment during three periods globally and at the country level for 2013. In total, 35 620 distinct sources of data were used and documented to calculated estimates for 301 diseases and injuries and 2337 sequelae. The comorbidity simulation provides estimates for the number of sequelae, concurrently, by individuals by country, year, age, and sex. Disability weights were updated with the addition of new population-based survey data from four countries. Findings Disease and injury were highly prevalent; only a small fraction of individuals had no sequelae. Comorbidity rose substantially with age and in absolute terms from 1990 to 2013. Incidence of acute sequelae were predominantly infectious diseases and short-term injuries, with over 2 billion cases of upper respiratory infections and diarrhoeal disease episodes in 2013, with the notable exception of tooth pain due to permanent caries with more than 200 million incident cases in 2013. Conversely, leading chronic sequelae were largely attributable to non-communicable diseases, with prevalence estimates for asymptomatic permanent caries and tension-type headache of 2·4 billion and 1·6 billion, respectively. The distribution of the number of sequelae in populations varied widely across regions, with an expected relation between age and disease prevalence. YLDs for both sexes increased from 537·6 million in 1990 to 764·8 million in 2013 due to population growth and ageing, whereas the age-standardised rate decreased little from 114·87 per 1000 people to 110·31 per 1000 people between 1990 and 2013. Leading causes of YLDs included low back pain and major depressive disorder among the top ten causes of YLDs in every country. YLD rates per person, by major cause groups, indicated the main drivers of increases were due to musculoskeletal, mental, and substance use disorders, neurological disorders, and chronic respiratory diseases; however HIV/AIDS was a notable driver of increasing YLDs in sub-Saharan Africa. Also, the proportion of disability-adjusted life years due to YLDs increased globally from 21·1% in 1990 to 31·2% in 2013. Interpretation Ageing of the world's population is leading to a substantial increase in the numbers of individuals with sequelae of diseases and injuries. Rates of YLDs are declining much more slowly than mortality rates. The non-fatal dimensions of disease and injury will require more and more attention from health systems. The transition to non-fatal outcomes as the dominant source of burden of disease is occurring rapidly outside of sub-Saharan Africa. Our results can guide future health initiatives through examination of epidemiological trends and a better understanding of variation across countries. © 2015 Elsevier Ltd
