When did AIDS treatment start in Africa?
In 1996 the effective combination therapy known as HAART became available for those living with HIV in rich countries. The new drugs were so effective that AIDS death rates in developed countries dropped by 84% over the next four years .
When did AIDS first become treatable?
How did HIV become manageable? Before 1996, when the first combination drug therapy became available, managing HIV was a burden for patients. The available medications were very highly toxic and didn't suppress the virus very well.
Who made the first treatment for AIDS?
Azidothymidine (AZT), a compound first synthesized by Jerome Horowitz, Ph. D., in 1964 as an anti-cancer drug, was among the drugs initially tested. In a preliminary clinical trial done largely in the NIH Clinical Center, NCI scientists showed that AZT could improve the immune function of AIDS patients.
When was AIDS epidemic in Africa?
Five million adults and children became newly infected with HIV in 2001, 3.5 million of them from sub-Saharan Africa. Three million people died from AIDS-related causes in 2001, and 2.2 million of these deaths were among sub-Saharan Africans. AIDS is now the leading cause of death in sub-Saharan Africa.
When were ARVs introduced in South Africa?
South Africa introduced free ARVs in the public sector in April 2004 after a lengthy battle between activists and former President Thabo Mbeki and Health Minister Dr Manto Tshabalala-Msimang, who questioned the link between HIV and AIDS, and ARVs' effectiveness.
Overview
History of spread
David Carr was an apprentice printer (usually mistakenly referred to as a sailor; Carr had served in the Navy between 1955 and 1957) from Manchester, England who died August 31, 1959, and was for some time mistakenly reported to have died from AIDS-defining opportunistic infections (ADOIs). Following the failure of his immune system, he succumbed to pneumonia. Doctors, baffled by what he had died from, preserved 50 of his tissue samples for inspection. In 1990, th…
Transmission from non-humans to humans
The majority of HIV researchers agree that HIV evolved at some point from the closely related simian immunodeficiency virus (SIV), and that SIV or HIV (post mutation) was transferred from non-human primates to humans in the recent past (as a type of zoonosis). Research in this area is conducted using molecular phylogenetics, comparing viral genomic sequences to determine relatedness.
Emergence
The discovery of the main HIV/SIV phylogenetic relationships permits explaining broad HIV biogeography: the early centres of the HIV-1 groups were in Central Africa, where the primate reservoirs of the related SIVcpz and SIVgor viruses (chimpanzees and gorillas) exist; similarly, the HIV-2 groups had their centres in West Africa, where sooty mangabeys, which harbour the related SIVsmm virus, exist. However, these relationships do not explain more detailed patterns of biog…
Pathogenicity of SIV in non-human primates
In most non-human primate species, natural SIV infection does not cause a fatal disease (but see below). Comparison of the gene sequence of SIV with HIV should, therefore, provide information about the factors necessary to cause disease in humans. The factors that determine the virulence of HIV as compared to most SIVs are only now being elucidated. Non-human SIVs contain a nef gene that down-regulates CD3, CD4, and MHC class I expression; most non-human SIVs, therefore…
Activism by AIDS patients and families
In New York City, Nathan Fain, Larry Kramer, Larry Mass, Paul Popham, Paul Rapoport, and Edmund White officially established the Gay Men's Health Crisis (GMHC) in 1982.
Also in 1982, Michael Callen and Richard Berkowitz published How to Have Sex in an Epidemic: One Approach. In this short work, they described ways gay men could be sexual and affectionate while dramatically reducing the risk of contracting or spreading HIV. Both authors were themselves ga…
Identification of the virus
In May 1983, a team of doctors at the Pasteur Institute in France including Françoise Barré-Sinoussi and Luc Montagnier reported that they had isolated a new retrovirus from lymphoid ganglions that they believed was the cause of AIDS. The virus was later named lymphadenopathy-associated virus (LAV) and a sample was sent to the U.S. Centers for Disease Control, which was later passed to the National Cancer Institute (NCI).
Case definition for epidemiological surveillance
Since June 5, 1981, many definitions have been developed for epidemiological surveillance such as the Bangui definition and the 1994 expanded World Health Organization AIDS case definition.
