Forty years ago this month the first men began dying of a mysterious disease in California that would later be identified as Aids.

It would go on to claim millions of lives across the world.

Here is a look at the discovery and the fight against the deadly condition.

In June 1981 US epidemiologists report five cases of a rare form of pneumonia in gay men from California, some of whom have died. Unusual versions of skin cancer are identified in others.

It is the first alert about Acquired Immune Deficiency Syndrome (Aids), still unknown and unnamed.

Doctors identify “opportunistic infections” among injected drug-users late in the year and in hemophiliacs and Haitian residents in the United States (mid-1982).

The term Aids appears for the first time in 1982.

In January 1983 researchers in France, Francoise Barre-Sinoussi and Jean-Claude Chermann, working under Luc Montagnier, identify the virus that “might be” responsible for Aids. It is dubbed LAV.

The following year, US specialist Robert Gallo is said to have found the “probable” cause of Aids, the retrovirus HTLV-III.

The two viruses turn out to be one and the same, and in May 1986 it becomes officially known as the human immuno-deficiency virus, or HIV.

Barre-Sinoussi and Montagnier win a Nobel prize in 2008 for their discovery.

In March 1987, the first anti-retroviral treatment known as AZT is authorized in the US. It is expensive and has many side effects.

The World Health Organization (WHO) declares December 1, 1988 the first World Aids Day, to raise awareness. By June the following year the number of Aids cases worldwide is estimated at more than 150,000.

US actor Rock Hudson is the first high-profile Aids death in October 1985. A host of other stars succumb to the disease, including British singer and Queen frontman Freddie Mercury (November 1991) and the legendary Russian dancer and choreographer Rudolf Nureyev (January 1993).

In 1994, Aids becomes the leading cause of death among Americans aged between 25 and 44.

A new class of drugs signals the start of combinations of different anti-retro-viral therapies.

1996 is the first year in which the number of Aids deaths declines in the US.

A report released by WHO and the Joint United Nations Programme on Aids (UNAids) in November 1999 estimates the number of people infected with HIV since it first appeared at 50 million, of whom 16 million have died.

Africa is the hardest-hit continent, with 12.2 million cases.

In February 2003, US president George W. Bush launches the President’s Emergency Plan for Aids Relief, or PEPFAR, to combat the spread of Aids in 15 of the hardest-hit areas of Africa and the Caribbean.

With an initial budget of $15 billion over its first five years, PEPFAR had by 2018 committed $70 billion to the Aids response.

The first known patient cured of HIV is announced. The “Berlin Patient,” later named as American Timothy Brown, underwent two transplants of bone marrow containing a mutation of a gene that blocks HIV from attacking host cells.

He underwent total body irradiation to treat leukemia and nearly did not survive the process.
