HIV/AIDS through time: our timeline | AIDS: on the trail of a pandemic

.

A strange syndrome appeared in Haiti, the United States and Canada in the early 1980s. The media then described it as a particular form of cancer that attacked the immune system of those affected. It was the birth of an unprecedented human and medical crisis. Our timeline.

Studies show that the virus was implanted in America via a only man, a Haitian, who would have traveled to the Congo.

Prof Gordon Hennigar may have autopsied the first AIDS victim in the United States.

    < li>An analysis published in the magazine Nature in 1998 shows the presence of HIV in a blood sample taken in 1959 from a man who died in the Republic of Congo (Belgian Congo at the time). This is the first documented case of a human being killed by HIV/AIDS.
  • A 49-year-old New Yorker of Haitian origin, nicknamed Ardouin A, dies of pneumocystosis, a disease now associated with AIDS. Pathologist Gordon Hennigar, who conducted the autopsy, repeatedly asserted that this patient probably died of AIDS.
  • The virus remains unknown for decades, but many cases will be diagnosed retrospectively, particularly in Africa. The HIV-2 variant (which will be identified in 1985) spreads in West Africa, particularly in Guinea-Bissau, from the mangabey monkey.
  • Studies show that the virus has taken hold in America through one man, a Haitian who is said to have traveled to the Congo.
  • In 1969, a 16-year-old boy from St. Louis, USA, died of an illness that left doctors speechless. Tests conducted 18 years after his death will show the presence of HIV. Robert Rayford is the first confirmed case of a person who has died of AIDS in the United States. Before dying, the young man said he had never received a blood transfusion and had never traveled outside the Midwest, which would therefore indicate the presence of the disease on American soil before 1966. on this case since the 1980s tend to show that he had had male partners.

  • In 1976, the members of a Danish family die one after the other of a strange disease. The father, a sailor, had visited Nigeria and Cameroon in the early 1960s and would have maintained contact with prostitutes. In the same year, a Canadian pilot reportedly contracted HIV in Zaire following a blood transfusion he had to receive after a plane crash.
  • In 1977, a San Francisco prostitute gives birth to the first of three children who will be diagnosed with HIV after they die. The mother, who died in 1987, was believed to have been infected before 1977.
  • In 1978, many American homosexual men as well as Tanzanian and Haitian heterosexuals showed symptoms that would later be described as those of AIDS.< /li>
  • Retrospective analyzes show that a Portuguese man was the first Westerner to die from an HIV-2 infection.

The first description of AIDS in the United States

  • In 1980, at the University Hospital of Los Angeles , Dr. Michael Gottlieb treats three gay men with similar clinical signs (weight loss, Kaposi's sarcoma, fever and pneumonia).
  • Dr. Gottlieb's patients died in 1981. The doctor sent their records to the Centers for Disease Control in Atlanta, which then disseminated the description of the disease throughout the United States. This makes it possible to identify 31 identical cases in less than 15 days.
  • The New York Times publishes a first article concerning AIDS, which speaks of a rare cancer diagnosed in 41 homosexuals.
  • Researchers recognize the emergence of a new disease that destroys the immune system and thus prevents sufferers from defending themselves against the most common infections.
  • Early research shows that the disease is transmitted by sexual and blood routes and that it does not strike only homosexuals. It also affects intravenous drug users and some people who have received blood transfusions.

  • In this same book, the author evokes the death in Quebec of the flight attendant Gaétan Dugas, nicknamed at the time the “zero patient”, who would have been responsible for the introduction of the #x27;outbreak in the United States. In 2016, a genetic analysis shows that the 31-year-old Quebecer was not the person who introduced HIV to the United States.
