HIV/AIDS
Age-standardized death rate from HIV/AIDS across countries, with trends from 1990 to 2021.
| # | Country | Rate | Region |
|---|
This page shows age-standardized death rates for hiv/aids across 204 countries, sourced from the IHME Global Burden of Disease Study 2023 via Our World in Data. Age-standardized rates adjust for differences in age structure between populations, enabling fair comparisons across countries and over time. The data spans from 1990 to the latest available year.
HIV/AIDS mortality patterns are shaped by healthcare access, public health infrastructure, socioeconomic conditions, and disease-specific prevention and treatment programs. Explore regional breakdowns, country comparisons, and historical trends using the tools and pages linked below.
Human Immunodeficiency Virus (HIV) attacks CD4+ T-lymphocytes, progressively dismantling the adaptive immune system until the host can no longer resist opportunistic infections — a stage known as Acquired Immunodeficiency Syndrome (AIDS). Transmission occurs through sexual contact, contaminated blood products, shared needles, and vertical mother-to-child routes during pregnancy, birth, or breastfeeding. Sub-Saharan Africa carries roughly two-thirds of the global HIV burden, though Eastern Europe and parts of Southeast Asia have experienced significant epidemics as well. Without treatment, median survival from seroconversion is approximately 8-10 years. The introduction of combination antiretroviral therapy (ART) in 1996 transformed HIV from a near-certain death sentence into a manageable chronic condition, reducing annual AIDS-related deaths from a peak of approximately 1.9 million in 2004 to under 650,000 by 2022. Despite this progress, 1.3 million new infections still occur each year, and treatment coverage gaps persist in low-income settings, making HIV one of the defining public health challenges of the modern era.
Effective HIV prevention integrates biomedical, behavioural, and structural approaches. Pre-exposure prophylaxis (PrEP) reduces acquisition risk by over 90% when taken consistently. Condom use, voluntary medical male circumcision, harm-reduction programmes for people who inject drugs, and elimination of mother-to-child transmission (EMTCT) are all proven interventions. The UNAIDS 95-95-95 targets aim for 95% of people living with HIV to know their status, 95% of those diagnosed to receive ART, and 95% on treatment to achieve viral suppression by 2030. Reaching these targets would effectively end AIDS as a public health threat.
Across the 210 countries tracked in this dataset, hiv/aids accounts for an average of 2.3% of total deaths. The highest share is recorded in Eswatini at 30.1%, while Slovenia records the lowest at 0.01%. These figures reflect the most recent available data and illustrate the vast geographic variation in hiv/aids mortality burden.
