In short
In 1983, researchers at the Pasteur Institute in Paris identified a novel retrovirus later named HIV, the pathogen responsible for AIDS. The discovery came as doctors worldwide were confronting a mysterious immune-system collapse in gay men, people who injected drugs, and recipients of blood transfusions. This finding transformed AIDS from a baffling clinical puzzle into a disease with an identifiable cause-and, eventually, the possibility of treatment.

Across 15 years, 8 pivotal moments.
Timeline
How it actually unfolded.
First AIDS cases documented
CDC reports unusual pneumonia in five gay men in Los Angeles. Two die within months. No known cause identified.
AIDS term coined
CDC adopts 'Acquired Immunodeficiency Syndrome' (AIDS) as official name for the emerging epidemic.
Montagnier's team isolates LAV
Luc Montagnier and colleagues at Pasteur Institute isolate a retrovirus from AIDS patient samples. Named LAV (Lymphadenopathy-Associated Virus).
HIV discovery published
Montagnier team's findings appear in Science journal, proposing LAV as the causative agent of AIDS.
HTLV-III identified independently
Robert Gallo's team at NIH announces isolation of HTLV-III. Subsequently confirmed as same virus as LAV; unified designation becomes HIV (Human Immunodeficiency Virus).
First HIV antibody test approved
FDA approves ELISA test for HIV antibodies, enabling blood screening and diagnosis.
AZT approved by FDA
First antiretroviral drug, azidothymidine (AZT), becomes available for HIV treatment, extending survival and reducing symptoms.
Protease inhibitors introduced
Combination antiretroviral therapy (HAART) with protease inhibitors transforms HIV from fatal to manageable chronic condition.

“We are dealing with something new and alarming. These patients present with opportunistic infections we rarely see except in the severely immunocompromised. Something is destroying their immune systems.”
- PredictiveExpertMay 1983
“We have isolated a new retrovirus from lymphoid tissue of a patient with lymphadenopathy. This virus may be the agent responsible for the acquired immunodeficiency.”
Synthesized from period accounts - Institut Pasteur press materials and Science journal submissions, 1983 - Montagnier's team was isolating what would become known as HIV, racing against American researchers to identify the causative agent of the emerging epidemic. - SupportiveOfficialSep 1983
“The epidemiological evidence suggests this disease spreads through intimate contact and blood. We must establish surveillance and identify risk factors immediately.”
Synthesized from period accounts - CDC Task Force meetings and public health advisories, 1983 - Curran led the CDC's investigation into the epidemic's spread, tasked with tracing transmission patterns amid limited understanding and scarce resources. - GrievingMediaJul 1983
“While gays are dying, the government sleeps. Public health officials treat this as a footnote. We are witnessing both a plague and a catastrophic failure of leadership.”
Synthesized from period accounts - San Francisco Chronicle reporting, 1983 - Shilts was among the few mainstream journalists covering the epidemic in real time, documenting government indifference and the crisis within gay communities. - PredictiveExpertAug 1983
“We cannot yet identify the cause, but the pattern is clear. Sexual transmission appears likely. We must educate people now about risk reduction, regardless of what the virus turns out to be.”
Synthesized from period accounts - New York gay health community discussions and medical conferences, 1983 - Sonnabend was treating gay patients in New York and challenging prevailing assumptions about transmission, while advocating for safe-sex education before the term existed.

Impact
What followed.
The identification of HIV in 1983 by Luc Montagnier's team marked the moment AIDS shifted from epidemic mystery to treatable infection. Within a decade, the virus's structure was mapped and drug targets identified. This discovery anchored four decades of virology, public health policy, and global pharmaceutical development-and remains foundational to pandemic preparedness.
