- In 1983, scientists discovered the virus that causes AIDS. The virus was at first named HTLV-III/LAV (human T-cell lymphotropic virus-type III/lymphadenopathy-associated virus) by an international scientific committee. This name was later changed to HIV (human immunodeficiency virus).

Who discovered HIV: Gallo, Montagnier or both? Dr. Luc Montagnier of the Pasteur Institute in Paris and Dr. Anthony Gallo of the National Cancer Institute in Washington both raced to find the cause of the disease. On January 23, 1983, Montagnier found a suspect virus he called LAV (Lymphadenopathy Associated Virus).

Comprehensive, up-to-date information on HIV/AIDS treatment and prevention from the University of California San Francisco AIDS case surveillance reported the highest number of new cases by date of diagnosis in 1993, but this was in part an artifact of the change in the AIDS case definition in 1993 to include a CD4-lymphocyte count below 200 cells/mm or CD4 percentage below 14%.

History of HIV/AIDS The authors proposed that HIV-1 originated in the area of French Equatorial Africa in the early 20th century (when the colonial abuses and forced labor were at their peak). Later researches proved these predictions mostly correct: HIV-1 groups M and O started to spread in humans in late 19th–early 20th century.

Where did HIV come from? Scientists identified a type of chimpanzee in West Africa as the source of HIV infection in humans. They believe that the chimpanzee version of the immunodeficiency virus (called simian immunodeficiency virus or SIV) most likely was transmitted to humans and mutated into HIV when humans hunted these chimpanzees for meat and came into contact with their infected blood.

- Scientific disinformation and the 1959 HIV-positive blood test from Africa. By predating HIV back to the 1930s, the chimp theory effectively discredits the man-made theory of AIDS, which dates the introduction of HIV to the late 1970s. Only time will tell whether the chimp theory will hold up to further scientific scrutiny.

HIV/AIDS and other sexually transmitted infections HIV/AIDS and other sexually transmitted infections. Sexually-transmitted infections have been known since ancient times; they remain, worldwide, a major public health problem, compounded by the appearance of HIV/AIDS around 1980. The most important sexually transmitted infections and infectious agents are:

HIV/AIDS AIDS was first recognized by the United States Centers for Disease Control and Prevention (CDC) in 1981 and its cause—HIV infection—was identified in the early part of the decade. HIV/AIDS has had a great impact on society, both as an illness and as a source of discrimination.

HIV/AIDS Genetic research indicates that HIV originated in west-central Africa during the late 19th or early 20th century. AIDS was first recognized by the United States Centers for Disease Control and Prevention (CDC) in 1981 and its cause—HIV infection—was identified in the early part of the decade.

HIV/AIDS Information (How he became infected is not known.) Genetic analysis of this blood sample suggested that HIV-1 may have stemmed from a single virus in the late 1940s or early 1950s. We know that the virus has existed in the United States since at least the mid-to late 1970s.

Timeline of HIV/AIDS 1 A San Francisco prostitute gives birth to the first of three children who were later diagnosed with AIDS. 2  The children's blood was tested after their deaths and revealed an HIV infection. 3  The mother died of AIDS in May 1987. September 24, The CDC defines a case of AIDS as a disease, at least moderately predictive of a defect in cell-mediated immunity, occurring in a person with no known cause for diminished resistance to that disease.

Who discovered HIV: Gallo, Montagnier or both? Many people will remember the heated contest over who discovered the virus that causes AIDS, and the patenting of the consequent blood tests, which took place between Dr. Luc Montagnier of the Pasteur Institute in Paris and Dr. Anthony Gallo at the National Cancer Institute in Washington.r. Luc Montagnier of the Pasteur Institute in Paris and Dr. Anthony Gallo of the National Cancer Institute in Washington both raced to find the cause of the disease.

Comprehensive, up-to-date information on HIV/AIDS treatment and prevention from the University of California San Francisco HIV infection resulting from blood transfusion has been documented repeatedly since the first case report in late 1982.(6-8,9) In the United States, almost all cases are due to blood transfused before March 1985, when HIV antibody testing became available to screen donated blood.

Researchers trace first HIV case to 1959 in the Belgian Congo Dr. David Ho and colleagues from the Aaron Diamond AIDS Research Center in New York told a conference they traced the very first case of HIV infection to a man living in what was then the Belgian Congo in 1959. The scientists found HIV in a blood sample taken from the man, who was a member of the Bantu tribe.

Where did HIV come from? For many years scientists theorized as to the origins of HIV and how it appeared in the human population, most believing that HIV originated in other primates. Then in 1999, an international team of researchers reported that they had discovered the origins of HIV-1, the predominant strain of HIV in the developed world.ormal tracking (surveillance) of AIDS cases began that year in the United States. In 1983, scientists discovered the virus that causes AIDS. The virus was at first named HTLV-III/LAV (human T-cell lymphotropic virus-type III/lymphadenopathy-associated virus) by an international scientific committee.

Who discovered HIV: Gallo, Montagnier or both? They concluded that the origin of the HIV isolate discovered by Gallo was the same as that discovered by Montagnier. Today it is generally agreed that Montagnier’s group was the first to identify HIV, although Gallo’s group insists it contributed significantly to demonstrating that it causes AIDS.

- Ryan White: his story 1  .... Ryan White was diagnosed with AIDS at age 13. He and his mother Jeanne White Ginder fought for his right to attend school, gaining international attention as a voice of reason about HIV/AIDS. .... 2  as told by his mother Jeanne White-Ginder. Ryan was diagnosed with AIDS on December 17, 1984. He was one of the first children, one of the first hemophiliacs to come down with AIDS, and it was definitely a time where there was no education and there was hardly any information on AIDS at the time.

HIV-2 In 1986, a second type of HIV, called HIV-2, was isolated from AIDS patients in West Africa, where it may have been present decades earlier. Studies of the natural history of HIV-2 are limited, but to date comparisons with HIV-1 show some similarities while suggesting differences.
