Timeline of HIV/AIDS
This is a timeline of HIV/AIDS, attempting to describe important events in the history of the virus and the disease.
|Time period||Development summary|
|1960s||Experts suggest that about 2,000 people in Africa may have been infected with HIV during this decade. Stored blood samples from an American malaria research project carried out in the Congo in 1959 prove one such example of early HIV infection. The 1960s and the following decade are known as the “silent” decades as it is likely that HIV already circulated sometime during these times but was unknown or not reported. The spread would start in 1970’s when the medical community becomes aware.|
|1970s||The first epidemic of HIV/AIDS is believed to have occurred in Kinshasa. The emerging epidemic in the Congolese capital is signalled by a surge in opportunistic infections, such as cryptococcal meningitis, Kaposi’s sarcoma, tuberculosis and specific forms of pneumonia. It is speculated that HIV is brought to the city by an infected individual who travelled from Cameroon by river down into the Congo. On arrival in Kinshasa, the virus would enter a wide urban sexual network and spread quickly, giving riseto the world’s first heterosexually-spread HIV epidemic.|
|1980s||AIDS crisis decade, starting with the acknowledgement of a new epidemics in the United States. From 1981 through 1987, the average life expectancy for people diagnosed with AIDS is 18 months. HIV begins its spread in Asia in the early to mid-1980s.|
|1990s||In the 1990s, a substantial increase in the number of people infected with HIV and dying of AIDS is recorded. In 1997, almost 3.5 million people are diagnosed with HIV per year. After 1997, the number of new diagnoses begins to decline and in 2015 it is reduced to 2.1 million per year.|
|2000s<||The number of AIDS-related deaths reaches a peak in 2004 and 2005 when in both years 2 million people die. Since then the annual number of deaths from AIDS declines as well and a decade later it is almost halved when 1.1 million people die in 2015.|
|Year||Month and date||Event type||Details|
|1920s||According to scientists, the origin of AIDS pandemic may be traced to this decade in the city of Kinshasa, in what is now the Democratic Republic of Congo.|
|1930||Infection||A complex computer model of the evolution of HIV-1 suggests that the first transfer of simian immunodeficiency virus (SIV) to humans occur around that year.|
|1940s||Infection||HIV-2 transferral from monkeys to humans in Guinea-Bissau is calculated at some point in the decade.|
|1959||Infection||Early documented HIV-1 infection is discovered in a preserved blood sample taken in 1959 from a man from Léopoldville in the Belgian Congo.|
|1960||Infection||A second early documented HIV-1 infection is discovered in a preserved lymph node biopsy sample taken in 1960 from a woman from Léopoldville, Belgian Congo.|
|1969||May||Notable death||16-year-old African-American Robert Rayford dies at the St. Louis City Hospital from Kaposi's sarcoma. In 1987 researchers at Tulane University School of Medicine would detect "a virus closely related or identical to" HIV-1 in his preserved blood and tissues.|
|1971||Diagnosis||The enzyme-linked immunosorbent assay (ELISA) is introduced by Swedish immunologist Peter Perlmann and Eva Engvall at Stockholm University in Sweden, as a test that uses antibodies and color change to identify a substance. ELISA would later be used for the detection of HIV antibodies in blood samples.|
|1972–1973||Infection||Researchers draw blood from 75 children in Uganda to serve as controls for a study of Burkitt's lymphoma. In 1985, retroactive testing of the frozen blood serum indicate that antibodies to a virus related to HIV are present in 50 of the children.|
|1975–1976||Infection||Norwegian sailor Arvid Noe, his wife, and his seven-year-old daughter die of AIDS. The sailor first presented symptoms in 1969, eight years after he first spent time in ports along the West African coastline. A gonorrhea infection during his first African voyage shows he was sexually active at this time. Tissue samples from the sailor and his wife were tested in 1988 and found to contain HIV-1 (Group O).|
