The U.S. epidemic began publicly on June 5, 1981, with CDC's report of five young men in Los Angeles with Pneumocystis pneumonia. CDC first used the term "AIDS" in September 1982, the first antibody test was licensed in 1985, AZT was approved in 1987, and the Ryan White CARE Act passed in 1990. Combination therapy in the mid-1990s, PrEP in 2012, and long-acting medicines since 2021 have since transformed HIV from a death sentence into a manageable condition.
1981–1985: naming a new epidemic
The first five cases were reported June 5, 1981[1]. Cases climbed quickly: by August 28, 1981, CDC had 108 reported cases, 107 in men, with 40% already dead. By December 31, 1981, the U.S. had 337 reported cases of severe immune deficiency — 321 adults and adolescents and 16 children under 13 — and 130 deaths[2].
On September 24, 1982, CDC used the term "AIDS" (Acquired Immune Deficiency Syndrome) for the first time and issued the first case definition. On September 9, 1983, CDC identified all major transmission routes and ruled out casual contact, food, water, air, and surfaces[2]. On March 2, 1985, FDA licensed ELISA, the first commercial HIV blood test, and U.S. blood banks began screening the supply. Stigma ran alongside the science: in a December 1985 Los Angeles Times poll, a majority of Americans favored quarantining people with AIDS[2].
1987–1995: AZT, ACT UP, and the Ryan White CARE Act
FDA approved AZT (zidovudine) on March 19, 1987 — the first HIV medication and the first antiretroviral[2]. ACT UP (AIDS Coalition to Unleash Power) formed in New York City on March 12, 1987, two days after Larry Kramer's speech calling for direct action, and held its first demonstration on Wall Street on March 24, 1987[3]. An October 11, 1988 ACT UP sit-in at FDA produced 176 arrests, and FDA announced faster drug-approval rules eight days later[2].
Ryan White, an Indiana teenager with hemophilia refused entry to middle school in 1985, died April 8, 1990 at 18. That August, the Ryan White CARE Act delivered $220.5 million in federal funds in its first year[2]. HRSA describes the CARE Act as funding medical and support services for low-income people with HIV, now reaching about half a million people a year[4]. AIDS became the leading cause of death for Americans aged 25–44 in 1994, and 500,000 U.S. AIDS cases were reported by October 31, 1995.
1995–2012: combination therapy, the ACA, and PrEP
FDA approved the first protease inhibitor in June 1995, beginning the era of highly active antiretroviral therapy; HAART became the standard of HIV care in 1997, and AIDS-related deaths fell 47% the following year[2]. New U.S. AIDS diagnoses declined for the first time in 1996.
The Affordable Care Act barred insurers from denying or dropping coverage for pre-existing conditions including HIV, ended lifetime benefit caps, created the Healthcare.gov Marketplace, and let states expand Medicaid — meaningful because Medicaid is the largest payer for HIV care in the U.S. and expansion removed the old requirement to wait for an AIDS diagnosis to qualify[5]. The U.S. HIV travel and immigration ban was lifted January 4, 2010, and the first comprehensive National HIV/AIDS Strategy was released July 13, 2010[2]. FDA approved Truvada for PrEP on July 16, 2012, launching the modern prevention era.
2019–today: EHE, U=U, and long-acting medicines
The Ending the HIV Epidemic in the U.S. (EHE) initiative launched February 5, 2019, with goals of cutting new HIV infections 75% by 2025 and 90% by 2030 across four pillars — diagnose, treat, prevent, respond — starting with 57 priority jurisdictions[6].
The scientific basis for Undetectable = Untransmittable was set by HPTN 052 (2015) and the PARTNER Study (2014); the federal government affirmed U=U on July 29, 2022[2]. Long-acting medicines followed: Cabenuva, the first complete injectable HIV treatment, was approved January 21, 2021; Apretude, injectable PrEP dosed every two months, on December 21, 2021; and Sunlenca (lenacapavir), the first capsid inhibitor, on December 22, 2022. Twice-yearly lenacapavir for PrEP was approved June 18, 2025.
Today about 1.2 million people aged 13 and older live with HIV in the U.S., with an estimated 31,800 new infections in 2022, down 12% from 2018[7]. In 2024, CDC recorded 38,793 HIV diagnoses and 4,296 HIV-related deaths[8].
Florida in the epidemic's history
Florida was an early epicenter. In western Palm Beach County, 79 AIDS cases were reported from July 1982 through September 1986 — 62 in Belle Glade, 10 in South Bay, and 7 in Pahokee — a cumulative incidence of 295 per 100,000 versus 10.8 per 100,000 nationally[9]. In Dade County, 4,223 cumulative AIDS cases were reported through 1990 — seventh-highest of any U.S. metropolitan area — with a 1990 incidence rate of 54.7 per 100,000 (fifth nationally) plus 163 pediatric cases, second-highest in the country[10]. Federal care money followed early: in October 1986, HRSA made $15.3 million available to four cities — New York, San Francisco, Los Angeles, and Miami[2]. Florida still carries a heavy burden today, with an HIV-related death rate of 2.8 per 100,000 in 2024[8].
