The Global HIV and AIDS Epidemic
HIV, the virus that causes AIDS, is one of the world’s most serious public health challenges. However, there is a global commitment to stopping new HIV infections and ensuring that everyone with HIV has access to HIV treatment. The latest statistics on HIV around the world include:
Number of People with HIV—In 2023, there were 39.9 million people across the globe with HIV. Of these, 38.6 million were adults (>15 years old), and 1.4 million were children (<15 years old). Additionally, 53% were women and girls. New HIV Infections—An estimated 1.3 million individuals worldwide acquired HIV in 2023, marking a 39% decline in new HIV infections since 2010 and a 60% decline since the peak in 1995. Women and girls accounted for 44% of all new HIV infections in 2023. HIV Testing & Knowledge of HIV Status—Approximately 86% of people with HIV globally knew their HIV status in 2023. About 5.4 million people did not know they had HIV and still needed access to HIV testing services. HIV testing is an essential gateway to HIV prevention, treatment, care, and support services. HIV Treatment Access—As of the end of 2023, 77% of all people with HIV (30.7 million people) were accessing antiretroviral therapy (ART) globally. HIV treatment access is key to the global effort to end AIDS as a public health threat. People with HIV who are aware of their status, take ART as prescribed, and get and keep an undetectable viral load can live long and healthy lives and will not transmit HIV to their HIV-negative partners through sex. HIV Care Continuum—The HIV care continuum refers to the sequence of steps a person with HIV takes from diagnosis through receiving treatment until their viral load is suppressed to an undetectable level. In 2023, among all people with HIV worldwide (diagnosed and undiagnosed), 86% knew their HIV status, 77% were accessing ART, and 72% were virally suppressed. Perinatal Transmission—In 2023, globally, 84% of pregnant people with HIV had access to ART to prevent transmitting HIV to their babies during pregnancy and childbirth and to protect their own health. AIDS-related Deaths—AIDS-related deaths have been reduced by 69% since the peak in 2004. In 2023, around 630,000 people died from AIDS-related illnesses worldwide, compared to 2.1 million people in 2004 and 1.3 million in 2010. Regional Impact—Certain regions of the globe are disproportionately affected by HIV. In 2023, there were 20.8 million people with HIV in eastern and southern Africa, 5.1 million in western and central Africa, 6.7 million in Asia and the Pacific, and 2.3 million in Western and Central Europe and North America. Challenges and Progress Despite advances in our scientific understanding of HIV and its prevention and treatment, as well as years of significant effort by the global health community and leading government and civil society organizations, too many people with HIV or at risk for HIV still do not have access to prevention, care, and treatment, and there is still no cure. The HIV epidemic not only affects the health of individuals but also impacts households, communities, and the development and economic growth of nations. Many of the countries hardest hit by HIV also suffer from other infectious diseases, food insecurity, and other serious problems. Promising signs. Despite these challenges, there have been successes and promising signs. New global efforts have been mounted to address the epidemic, particularly in the last decade. The number of people who have newly acquired HIV has declined over the years. In addition, the number of people with HIV receiving treatment in resource-poor countries has dramatically increased in the past decade, and progress has been made in preventing perinatal transmission of HIV and keeping pregnant people alive. Unequal progress. However, despite the availability of a widening array of effective HIV prevention tools and methods and a massive scale-up of HIV treatment in recent years, UNAIDS cautions there has been unequal progress in reducing new HIV infections, increasing access to treatment, and ending AIDS-related deaths, with many vulnerable people and populations left behind. Social inequalities and exclusion continue to be key barriers, and our response to HIV/AIDS across the globe may be in jeopardy without continued commitment and strong partnerships. U.S. Response to the Global Epidemic The U.S. President's Emergency Plan for AIDS Relief (PEPFAR) is the U.S. Government’s response to the global HIV/AIDS epidemic and represents the largest commitment by any nation to address a single disease in history. Through PEPFAR, which was launched in 2003, the U.S. has supported a world safer and more secure from infectious disease threats. It has demonstrably strengthened the global capacity to prevent, detect, and respond to new and existing risks—which ultimately enhances global health security and protects America’s borders. Among other global results, as of September 30, 2023, PEPFAR has provided HIV testing services for more than 71.1 million people and supported lifesaving ART for nearly 20.5 million men, women, and children. PEPFAR has also enabled 5.5 million babies to be born HIV-free to parents living with HIV and is directly supporting over 327,000 health workers to deliver and improve HIV care and other health services. Strong partnerships with countries and communities are key to these successes, along with U.S. Government support for the global HIV/AIDS response. In conclusion, the global HIV and AIDS epidemic remains a significant public health challenge, but progress has been made in reducing new infections, increasing access to treatment, and preventing AIDS-related deaths. Continued commitment, strong partnerships, and a focus on addressing social inequalities are essential to ending the epidemic and ensuring that everyone with HIV has access to the care and support they need.
