HIV / AIDS Timeline

Our timeline covers the early days of HIV / AIDS but will be updated to cover major current day events.


The first recorded AIDS cases in the U.S. occurred in New York.

June 1981

Unusual immune system failure among gay men begins surfacing in the United States. These failures included diseases which were only found in people with suppressed immune systems. Five young men reported having Pneumocystis Carnii, a very rare form of pneumonia.

July 1981

The Centers for Disease Control and Prevention (CDC) report that Kaposis Sarcoma (KS), an uncommon form of cancer, has been found in 26 gay men from New York City and California. KS is usually found in older men. This, combined with the earlier reports of Pneumocystis Carnii, first led doctors to believe that a new immune-deficiency related disease was on the uprise. The disease was initially names GRID, for Gay-Related Immune Deficiency, because it was predominantly found among homosexuals. GRID appeared to be a lifestyle-associated illness, linked to excessive stress to the immune system. One hypothesis regarding the cause of the new disease placed the blame on amyl nitrate, or “poppers” which are used to heighten sexual pleasure. Researchers believed that GRID was caused by a highly infectious agent which depleted T cells, and could be transmitted through intercourse, blood, or blood products from mother to fetus.

July 1982

May 1999

  • New in vitro studies show that HIV resistant to nelfinavir is less fit than virus resistant to other HIV protease inhibitors. These studies may explain clinical observations that patients failing first-line HAART regimens including nelfinavir are more likely than those failing other regimens to respond well to subsequent therapy if such failures are caught early.
  • A report from the American Academy of Pediatrics recommends that, save for those who are extremely immunocompromised, all HIV-infected children and young adults should receive the measles, mumps, and rubella vaccine.
  • The FDA approves the first home test kit for HCV, Home Access Health’s Hepatitis C Check, which will enable users to take their own blood sample and send it in anonymously to be tested.
  • The Centers for Disease Control and Prevention (CDC) announces that only 6500 people out of a possible 1 million have been notified that they may be at risk for infection with the hepatitis C virus.
  • In a study published in the Proceedings of the National Academy of Sciences, researchers Zhi-Qiang Zhang and Ashley Hasse, MD, report that HAART may regenerate the follicular dendritic cell network.
  • A report in Clinical Infectious Diseases suggests that discontinuing lamivudine in persons co-infected with HIV and hepatitis B may cause serious flares of hepatitis B.
  • AIDS becomes the world’s deadliest infectious disease in the last year, overtaking tuberculosis and moving up to fourth place among all causes of death worldwide, according to the World Health Organization.
  • An independent Data Safety Monitoring Board recommends ending the Phase III trial of HIV-1 immunogen because clinical differences were not observed between placebo and treatment groups and were unlikely to be observed in the near term.
  • New data indicate that adults over 50 are increasingly at risk for HIV infection. A study from the CDC suggests that older people are much less likely to have protected sex than younger people, primarily because they do not see themselves at risk.
  • A study at NIAID of patients stopping HAART has enrolled 18. Ten have gone without their drugs long enough to produce results; in all of them, the virus has rebounded.
  • The Clinton administration releases new guidelines to ease the availability of marijuana for medical research.
  • Researchers at the Aaron Diamond AIDS Research Center report that HIV can be recovered from 8 patients whose viral load had remained unquantifiable from 2-3 years. They suggest it will take at least 7-10 years of HAART to eliminate the reservoir and they have doubts that it is possible.
  • Doctors at Yale University report patients using methadone and nevirapine can develop symptoms of methadone withdrawal unless their dose of methadone is increased.
  • In a review of different salvage regimens, Roy Gulick, MD, reports at the 2nd International Workshop on Salvage Therapy for HIV-1 Infection that viral suppression to fewer than 400 copies/mL was achieved in only 20-40% of patients, a sharp contrast to success rates of up to 90% for first-line therapy.

June 1999

  • A study published in Psychosomatic Medicine reports the probability of progressing to AIDS during a 5.5-year study period was 2 to 3 times higher for HIV-infected men with more than average stress or with less than average support than for those below the median on stress and above the median on social support.
  • A study in the Journal of Immunology suggests that some human major histocompatibility complex proteins may slow or hasten the speed at which HIV-1 progresses.

  • Veronica Miller, MD, from the JW Goethe Universitat, Frankfurt, presents results from a study of the effects of treatment interruptions in subjects with previous failure to multiple treatment regimens. The majority of patients’ HIV reverts to wild-type with a better virologic response upon re-administration of multidrug rescue therapies. The patients, however, lose substantial numbers of CD4 T cells in the process.
  • Investigators report in the Journal of Clinical Endocrinology and Metabolism on evidence that a number of metabolic abnormalities found in HIV-positive women may be unrelated to the use of protease inhibitors. Hyperinsulinemia and truncal adiposity have been observed in HIV-infected women prior to initiation of protease inhibitor therapy.
  • British doctors report in The Lancet the case of an HIV-infected patient who died while receiving sildenafil, ritonavir and saquinavir. The patient had no history of nitrate drug use, hypertension, diabetes or family history of ischemic heart disease. However, he had a 30-year history of smoking and currently smoked 30 cigarettes per day.
  • Data from the Johns Hopkins HIV clinic show that 63% of patients taking their first protease inhibitor containing regimen fail to suppress their viral below 500 copies/mL at one year. The charts of 114 patients who had experienced virologic failure were reviewed. Among this group, 242 unique antiretroviral regimens were identified, and each patient had an average of 9.4 regimen events (defined as a new drug regimen or drug holiday lasting at least 2 weeks). Only 3 patients (2.6%) shared an identical sequence of events.
  • Patient selection and dosing begin in the Phase II clinical trial of pentafuside. The trial will assess the antiviral activity and long-term safety of pentafuside when used in combination with other antiretroviral drugs.
  • The in vitro data presented at the 3rd International Workshop on HIV Drug Resistance and Treatment Strategies suggest that tipranavir, the first in a new class of nonpeptidic protease inhibitors, is active against strains of HIV that are highly resistant to all 4 approved protease inhibitors.
  • ViroLogic, Inc. announces the commercial availability of PhenoSense, the company’s rapid phenotypic HIV drug resistance assay.
  • Visible Genetics Inc. announces the introduction of a new product known as TruPrep that makes genotyping possible for HIV-infected patients with viral load levels as low as 60 copies/mL.
  • Gilead Sciences submits a New Drug Application to the FDA for adefovir dipivoxil. The FDA informs Gilead Sciences that its planned trade name, Preveon, should not be adopted, as it is in conflict with another recently approved pharmaceutical product.

July 1999

  • During the 1st International Workshop on Adverse Drug Reactions and Lipodystrophy in HIV, Kees Brinkman, MD, proposes that lipodystrophy may be caused by mitochondrial dysfunction and that the mitochondrial toxicity of NRTIs might be an important factor in the pathogenesis of HAART-related lipodystrophy.
  • Trimeris Inc. and Hoffmann-LaRoche conclude an agreement for the full-scale clinical testing and development of Trimeris’s 2 novel anti-HIV fusion inhibitors, pentafuside and T-1249. Roche will market the compounds worldwide.

  • A report in Archives of Internal Medicine Online reveals that over 50% of the HIV-infected patients who started a drug regimen that included protease inhibitors in an academic clinical practice did not achieve durable suppression of viral replication.
  • French researchers report in The New England Journal of Medicine 10 cases of alopecia associated with indinavir therapy. Doctors at the University of Texas M.D. Anderson Cancer Center note that shorter treatment time for high-risk cervical cancer in HIV-infected patients is associated with better health outcomes.
  • The number of people dying from AIDS in the United States is still falling but much more slowly, according to the CDC. The decline in the AIDS mortality rate—the number of persons who die as a percentage of those who have the disease—was 20% in 1997-98 compared to 42% in 1996-97.

September 1999

  • Researchers from the University of California at San Diego report in The Journal of the American Medical Association an analysis of 141 patients finding 3 HIV-infected patients with a more than ten-fold resistance to one or more AIDS drugs. More than one quarter of the patients showed reduced susceptibility to at least one drug. The range of the reduction was from 2.5 to 10 fold. The patients, who were enrolled from 1989 to 1998, were located in San Diego, Los Angeles, Dallas, Denver and Boston.
  • Research from Spanish investigators suggests that individuals who are depressed and who have a perceived lack of social support have difficulty adhering to antiretroviral drug therapies for HIV infection.
  • Investigators from the US Naval Medical Center in San Diego report in the Annals of Internal Medicine that the flu vaccine is extremely effective in HIV-1-infected individuals.

Those receiving amprenavir were more likely to experience nausea, vomiting and rash when compared to those receiving placebo.
  • Data presented at the 39th ICAAC compares 2 protease-free drug combinations containing stavudine and didanosine, with either lamivudine or nevirapine, to a combination of stavudine, didanosine, and indinavir. At 48 weeks, virologic and CD4 T cell responses were similar for the 3 arms. When the arms were compared using a viral load test with a 50 copies/mL cutoff, the lamivudine, stavudine and didanosine arm did not perform as well, nor did persons with the highest baseline viral loads do as well on the protease-sparing arms when measured by the more stringent 50 copies/mL cutoff.
  • Anthony Fauci, MD, reports that all the patients in the NIAID treatment interruption study had viral rebounds. The virus reappeared in 3 to 5 weeks for the majority of subjects. However, the virus was resuppressed by restarting HAART. Another study by Martin Markowitz, MD, of the Aaron Diamond AIDS Research Center tested 4 recently infected patients who went off antiretrovirals after 3 years of therapy. The virus again reappeared in the patients after 14 to 26 days without treatment.

  • Calypte Biomedical Corp.’s “Day Assay” license for its HIV blot assay is approved by the FDA. The assay shows the presence of antibodies to HIV in serum samples within 5 hours.

December 1999

  • A recent survey of several hundred homosexual men in West Hollywood reported in AIDS Alert finds that attitudes towards HIV and AIDS are making gay men more at ease with the virus, causing some to return to high-risk sexual situations. One reason for the growing complacency is the advancement in treatment with protease inhibitors.
  • Researchers from the University of California at Los Angeles, the Rand Corp. and 8 other institutions find that one third of HIV-infected patients in the US forgo medical care because of the time or money it costs them. Minorities, women, drug abusers and those in poverty were the most likely to skip treatment and instead work or spend the money for food and shelter.
