LONDON, Dec 1 (Openly) - On the 30th World AIDS Day, the following timeline shows how the epidemic spread around the world, progress made to combat it and challenges that remain.

1920s - HIV, the virus that causes AIDS, is thought to have spread from chimpanzees in West Africa to humans.

1981 - The first cases of AIDS are reported among gay men in Los Angeles, San Francisco and New York.

1982 - The disease is found in several European countries, including Britain and France, and the term AIDS, meaning Acquired Immune Deficiency Syndrome, is first used.

1983 - AIDS is first recorded among female partners of men with the disease, suggesting that HIV can be transmitted via heterosexual sex.

1987 - Princess Diana opens the first HIV ward in a British hospital and is photographed holding hands with an AIDS patient.

1991 - Freddie Mercury, frontman of the rock group Queen, announces that he has AIDS and dies a day later from pneumonia.

1996 - A drug treatment called highly active antiretroviral therapy (HAART) is introduced, drastically lowering death and transmission rates.

2000 - The United Nations adopts the Millennium Development Goals which include a goal to reverse the spread of HIV and AIDS.

2006 - Male circumcision is found to reduce the sexual transmission of HIV between men and women by 60 percent.

2012 - The oral prophylactic drug PrEP is approved for HIV-negative people to prevent sexual transmission of the virus.

2014 - UNAIDS, the United Nations HIV/AIDS body, sets a goal of reducing the number of new HIV infections and AIDS-related deaths by 90 percent by 2030.

2017 - For the first time, half of all people living with HIV worldwide are receiving antiretroviral treatment.
