HIV/AIDS in the United States. The human immunodeficiency virus (HIV) epidemic has been a major public health issue in the United States since it was first clinically observed in the early 1980s. While significant advances in treatment and prevention have transformed HIV from a fatal diagnosis to a manageable chronic condition, disparities in infection rates and access to care persist. The domestic response has involved major federal initiatives, community activism, and ongoing biomedical research.

Epidemiology and demographics

Approximately 1.2 million people in the United States were living with HIV at the end of 2021, with about 13% unaware of their status. The Centers for Disease Control and Prevention (CDC) reports that annual new infections have declined overall but remain disproportionately high among certain populations. Geographic disparities are pronounced, with the highest burden in the Southern United States, particularly in urban areas like Atlanta, Miami, and Baton Rouge, Louisiana. Key affected groups include gay and bisexual men, particularly young Black Americans and Hispanic and Latino Americans, as well as transgender women and people who inject drugs. The National Institutes of Health and the CDC continue to monitor these trends through surveillance systems.

History and timeline

The first cases of what would become known as AIDS were reported in 1981 by the CDC in its Morbidity and Mortality Weekly Report, describing rare illnesses among previously healthy gay men in Los Angeles and New York City. The virus was isolated in 1983 by researchers at the Institut Pasteur and later at the National Cancer Institute. The 1980s were marked by fear, stigma, and the emergence of activist groups like the AIDS Coalition to Unleash Power (ACT UP). Key events include the establishment of the Ryan White CARE Act in 1990, the introduction of protease inhibitors and Highly Active Antiretroviral Therapy (HAART) in the mid-1990s, and the President's Emergency Plan for AIDS Relief (PEPFAR) launch in 2003.

Prevention and public health response

Prevention strategies have evolved from early safer sex education campaigns to include a robust toolkit of biomedical interventions. The CDC promotes widespread testing, condom use, and harm reduction services like syringe service programs. Major biomedical advances include Pre-exposure prophylaxis (PrEP), using medications like Truvada and Descovy, and Post-exposure prophylaxis (PEP). The U.S. Preventive Services Task Force recommends routine HIV screening. Public health campaigns, such as the Act Against AIDS initiative and the Ending the HIV Epidemic in the U.S. plan, coordinate federal, state, and local efforts. Community-based organizations like the San Francisco AIDS Foundation are critical to outreach.

Treatment and care

The standard of care is Antiretroviral therapy (ART), which suppresses the Viral load to undetectable levels, improving health and preventing transmission, a concept known as Undetectable = Untransmittable (U=U). Treatment guidelines are established by the Department of Health and Human Services (HHS). Landmark clinical trials, such as those conducted by the AIDS Clinical Trials Group, have driven drug development. Access to care is facilitated by the Ryan White HIV/AIDS Program, Medicaid, and the Affordable Care Act. Major pharmaceutical companies like Gilead Sciences and ViiV Healthcare develop and market antiretroviral drugs. Managing Opportunistic infections remains a component of care for those with advanced disease.

Impact on affected communities

The epidemic has had a profound and lasting impact, particularly on the LGBT community, which mobilized through groups like ACT UP and the Gay Men's Health Crisis. The arts were deeply affected, memorialized in works like the NAMES Project AIDS Memorial Quilt and the play Angels in America. The epidemic exacerbated existing inequalities, heavily impacting Black Americans and other minority communities. Long-term survivors, sometimes called the AIDS generation, face unique challenges including aging with HIV. Stigma and discrimination, addressed by laws like the Americans with Disabilities Act, continue to be significant barriers.

Policy and funding

The federal response is spearheaded by multiple agencies, primarily the CDC, the National Institutes of Health (NIH), and the Health Resources and Services Administration (HRSA). The largest source of direct care funding is the Ryan White HIV/AIDS Program. Research funding flows through the National Institute of Allergy and Infectious Diseases, led for decades by Anthony Fauci. The Affordable Care Act improved insurance coverage for people with HIV. Legislative actions include the HIV Organ Policy Equity Act and ongoing efforts to modernize laws criminalizing HIV exposure. The domestic budget is distinct from but related to the global President's Emergency Plan for AIDS Relief (PEPFAR).
