This is a timeline of HIV/AIDS , including cases before 1980.
Researchers estimate that some time in the early 20th century, a form of Simian immunodeficiency virus found in chimpanzees (SIVcpz) first entered humans in Central Africa and began circulating in Léopoldville (modern-day Kinshasa) by the 1920s. [1] [2] [3] This gave rise to the pandemic form of HIV (HIV-1 group M); other zoonotic transmissions led to the other, less prevalent, subtypes of HIV. [3] [4]

The Duesberg hypothesis is the claim that AIDS is not caused by HIV, but, instead, that AIDS is caused by noninfectious factors such as recreational and pharmaceutical drug use and that HIV is merely a harmless passenger virus. The hypothesis was popularized by University of California, Berkeley professor Peter Duesberg, from whom the hypothesis gets its name. The scientific consensus is that the Duesberg hypothesis is incorrect and that HIV is the cause of AIDS. The most prominent supporters of the hypothesis are Duesberg himself, biochemist and vitamin proponent David Rasnick and journalist Celia Farber. The scientific community generally contends that Duesberg's arguments in favor of the hypothesis are the result of cherry-picking predominantly outdated scientific data and selectively ignoring evidence that demonstrates HIV's role in causing AIDS.
The spread of HIV/AIDS has affected millions of people worldwide; AIDS is considered a pandemic. The World Health Organization (WHO) estimated that in 2016 there were 36.7 million people worldwide living with HIV/AIDS, with 1.8 million new HIV infections per year and 1 million deaths due to AIDS. Misconceptions about HIV and AIDS arise from several different sources, from simple ignorance and misunderstandings about scientific knowledge regarding HIV infections and the cause of AIDS to misinformation propagated by individuals and groups with ideological stances that deny a causative relationship between HIV infection and the development of AIDS. Below is a list and explanations of some common misconceptions and their rebuttals.
Kaposi's sarcoma-associated herpesvirus (KSHV) is the ninth known human herpesvirus; its formal name according to the International Committee on Taxonomy of Viruses (ICTV) is Human gammaherpesvirus 8, or HHV-8 in short. Like other herpesviruses, its informal names are used interchangeably with its formal ICTV name. This virus causes Kaposi's sarcoma, a cancer commonly occurring in AIDS patients, as well as primary effusion lymphoma, HHV-8-associated multicentric Castleman's disease and KSHV inflammatory cytokine syndrome. It is one of seven currently known human cancer viruses, or oncoviruses. Even after many years since the discovery of KSHV/HHV8, there is no known cure for KSHV associated tumorigenesis.
An opportunistic infection is an infection caused by pathogens that take advantage of an opportunity not normally available. These opportunities can stem from a variety of sources, such as a weakened immune system, an altered microbiome, or breached integumentary barriers. Many of these pathogens do not necessarily cause disease in a healthy host that has a non-compromised immune system, and can, in some cases, act as commensals until the balance of the immune system is disrupted. Opportunistic infections can also be attributed to pathogens which cause mild illness in healthy individuals but lead to more serious illness when given the opportunity to take advantage of an immunocompromised host.
AIDS-defining clinical conditions is the list of diseases published by the Centers for Disease Control and Prevention (CDC) that are associated with AIDS and used worldwide as a guideline for AIDS diagnosis. CDC exclusively uses the term AIDS-defining clinical conditions, but the other terms remain in common use.
AIDS is caused by a human immunodeficiency virus (HIV), which originated in non-human primates in Central and West Africa. While various sub-groups of the virus acquired human infectivity at different times, the present pandemic had its origins in the emergence of one specific strain – HIV-1 subgroup M – in Léopoldville in the Belgian Congo in the 1920s.
WHO Disease Staging System for HIV Infection and Disease in Adults and Adolescents was first produced in 1990 by the World Health Organization and updated in September 2005. It is an approach for use in resource limited settings and is widely used in Africa and Asia and has been a useful research tool in studies of progression to symptomatic HIV disease.
The CDC Classification System for HIV Infection is the medical classification system used by the United States Centers for Disease Control and Prevention (CDC) to classify HIV disease and infection. The system is used to allow the government to handle epidemic statistics and define who receives US government assistance.
Infection with HIV, a retrovirus, can be managed with treatment but without treatment can lead to a spectrum of conditions including AIDS.
HIV/AIDS was recognised as a novel illness in the early 1980s. An AIDS case is classified as "early" if the death occurred before 5 June 1981, when the AIDS epidemic was formally recognized by medical professionals in the United States.
Pneumocystis pneumonia (PCP), also known as Pneumocystis jirovecii pneumonia (PJP), is a form of pneumonia that is caused by the yeast-like fungus Pneumocystis jirovecii.
David J. Acer was an American dentist who allegedly infected six of his patients, including Kimberly Bergalis, with HIV. The Acer case is considered the first documented HIV transmission from a healthcare worker to a patient in the United States, though the means of transmission remain unknown. The high-profile case led to public controversy regarding HIV testing and disclosure for healthcare workers.
Kaposi's sarcoma (KS) is a type of cancer that can form masses in the skin, in lymph nodes, in the mouth, or in other organs. The skin lesions are usually painless, purple and may be flat or raised. Lesions can occur singly, multiply in a limited area, or may be widespread. Depending on the sub-type of disease and level of immune suppression, KS may worsen either gradually or quickly. Except for Classical KS where there is generally no immune suppression, KS is caused by a combination of immune suppression and infection by Human herpesvirus 8.
Joel D. Weisman D.O. was one of the first to identify a pattern of illnesses that was ultimately diagnosed as AIDS during his work as a general practitioner in the United States. He later became an advocate for the development of treatments and prevention of the disease.
Michael Stuart Gottlieb is an American physician and immunologist known for his 1981 identification of acquired immune deficiency syndrome (AIDS) as a new disease, and for his HIV/AIDS research, HIV/AIDS activism, and philanthropic efforts associated with HIV/AIDS treatment.
Linda Jane Laubenstein was an American physician and early HIV/AIDS researcher. She was among the first doctors in the United States to recognize the AIDS epidemic of the early 1980s; she co-authored the first article linking AIDS with Kaposi's sarcoma.
The stages of HIV infection are acute infection, latency, and AIDS. Acute infection lasts for several weeks and may include symptoms such as fever, swollen lymph nodes, inflammation of the throat, rash, muscle pain, malaise, and mouth and esophageal sores. The latency stage involves few or no symptoms and can last anywhere from two weeks to twenty years or more, depending on the individual. AIDS, the final stage of HIV infection, is defined by low CD4+ T cell counts, various opportunistic infections, cancers, and other conditions.
Sandy Ford was a drug technician for the Centers for Disease Control in Atlanta, Georgia. In April 1981, she identified unusual clusters of young homosexual patients in New York and California with pneumocystis pneumonia and Kaposi's sarcoma and alerted her supervisor about it. Those patients had HIV/AIDS; pneumocystis pneumonia and Kaposi's sarcoma were later found to be AIDS-defining diseases.
Social and political activism to raise awareness about HIV/AIDS, as well as to raise funds for effective treatment and care of people with AIDS (PWAs), has taken place in multiple nations across the world since the 1980s. As a disease that began in marginalized populations, efforts to mobilize funding, treatment, and fight discrimination have largely been dependent on the work of grassroots organizers directly confronting public health organizations as well as politicians, drug companies, and other institutions.
Joyce Wallace was a pioneering AIDS physician. She was among the first to identify AIDS in the 1980s and worked to stop its spread among New York City's prostitutes.
Irene Haske, a spokeswoman at the National Institutes of Health in Bethesda, Maryland, where Mr. Cohn died, said the primary cause of his death was cardio-pulmonary arrest, with "dementia" and "underlying HTLV III
The impact of AIDS on the dance music industry has been felt by many on an excruciatingly personal level. News this week of Prelude artist Sharon Redd's recent death due to AIDS once again brought reality into chillingly clear focus.
