50 Fun Facts About HIV and AIDS

Which Queen frontman confirmed he had AIDS in a statement issued the day before he died in 1991?

Freddie Mercury died of bronchial pneumonia resulting from AIDS on 24 November 1991, and the next April his bandmates staged a Wembley tribute concert that launched the Mercury Phoenix Trust.

Which NBA star announced he was HIV-positive and retired in November 1991, then won Olympic gold in 1992?

Magic Johnson's announcement triggered a surge in AIDS diagnoses among heterosexual men who came forward for testing, which researchers call the 'Magic Johnson effect'. He co-captained the 1992 Dream Team in Barcelona.

Timothy Ray Brown, the first person cured of HIV after a 2007 stem-cell transplant, was known by what nickname?

The Berlin Patient got his name at a 2008 conference to protect his anonymity; his donor carried a rare inherited variant that stops HIV attaching to cells. He went public in 2010, saying he did not want to be the only person cured.

Which of these body fluids does not transmit HIV, despite a persistent myth that it does?

Saliva, sweat and tears carry no risk unless visibly contaminated with blood, and no insect can transmit the virus either; the routes that matter are sex, shared needles, transfusions and mother-to-child.

Which Foundation novelist's 1992 death from HIV, caught via a 1983 transfusion, stayed a family secret until 2002?

Isaac Asimov's family hid the cause of his death for fear that anti-AIDS prejudice would extend to them; the virus came from a blood transfusion during triple bypass surgery, and his widow Janet finally revealed it in his autobiography.

Which royal opened the UK's first dedicated AIDS ward in 1987 and held a patient's hand to challenge the stigma?

Princess Diana's gesture at London's Middlesex Hospital made front pages at a time when many believed the virus spread by touch; she was named Woman of the Year 1987 for it and returned in 1991 to hug a patient.

Which colour, first worn as a ribbon by Jeremy Irons at the 1991 Tony Awards, became the symbol of AIDS awareness?

Red was chosen for its link to blood and passion, and the ribbon was first worn on screen by Jeremy Irons at the 1991 Tony Awards. The inspiration was the yellow ribbons honouring Gulf War troops.

World AIDS Day, proposed by two WHO press officers and first held in 1988, falls on which date?

1 December was picked by James Bunn, a former TV journalist, because it fell after the US elections but before Christmas, maximising news coverage. It has been observed every year since 1988.

Which star of Pillow Talk, a friend of the Reagans, became in 1985 the first major US celebrity to die of AIDS?

Rock Hudson's disclosure more than doubled private donations to AIDS research, and shortly before his death he gave $250,000 to help launch amfAR. His friend Ronald Reagan did not mention AIDS publicly until that September.

Tom Hanks won his first Oscar as a lawyer with AIDS suing the firm that fired him in which 1993 film?

Philadelphia also won Bruce Springsteen an Oscar for 'Streets of Philadelphia', and it was among the first mainstream Hollywood films to confront HIV/AIDS and homophobia, with Denzel Washington as the reluctant lawyer who takes the case.

HIV mainly infects which type of white blood cell, whose falling count doctors use to stage the infection?

CD4 T cells act as the immune system's coordinators, releasing cytokines that direct other immune cells, so losing them leaves the body open to infections it would normally shrug off.

By definition, HIV infection becomes AIDS once the CD4 count drops below how many cells per microlitre?

200 is the threshold, against a healthy range of roughly 500 to 1,200 cells, and without treatment around half of people with HIV cross it within ten years.

Which Paris institute isolated the virus behind AIDS in 1983, earning two of its scientists a 2008 Nobel Prize?

Institut Pasteur researchers Françoise Barré-Sinoussi and Luc Montagnier shared the 2008 Nobel Prize in Physiology or Medicine, while the American lab that claimed co-discovery was left out. They first called the virus LAV.

What does PrEP stand for, the daily pill regimen the FDA first approved in 2012 to prevent HIV infection?

Pre-exposure prophylaxis with the pill Truvada, a combination of emtricitabine and tenofovir, offers around 99% protection when taken every day. The WHO issued its own PrEP guidelines the same year.

The CDC's first report of what became AIDS, in June 1981, described a rare pneumonia in five men in which city?

Los Angeles doctors had seen Pneumocystis pneumonia, a fungal infection previously confined to severely immunosuppressed patients, in five previously healthy men. Within 18 months similar clusters appeared across the country.

Which acronym, soon dropped as misleading, did US doctors briefly apply to the syndrome in 1982 before 'AIDS'?

GRID stood for 'gay-related immune deficiency', a label abandoned by August 1982 once the same infections appeared in patients who were not gay men, and the CDC coined 'AIDS' in its place.

Ryan White, the Indiana teenager barred from school after contracting HIV from a blood product, had which condition?

Haemophilia treatment with pooled factor VIII infected nearly 90% of haemophiliacs treated between 1979 and 1984 with HIV or hepatitis C, and Congress passed the Ryan White CARE Act four months after his death in 1990.

Which drug, shelved in the 1960s as a failed cancer treatment, became the first approved HIV antiretroviral in 1987?

AZT was synthesised in 1964 under a cancer grant and shelved after proving inert in mice; it went from first lab test against HIV to approval in just 25 months. Its early dose was 400 mg every four hours, day and night.

Which group, formed by 300 New Yorkers two days after a 1987 speech, protested under the slogan 'Silence = Death'?

ACT UP's first action, two weeks after it formed, saw 250 members block Wall Street to demand access to experimental AIDS drugs; the pink-triangle 'Silence = Death' poster came from a separate art collective.

Cleve Jones's NAMES Project, begun in San Francisco in 1987 with panels the size of a grave, takes what form?

A quilt was what Jones saw when mourners taped name placards to a federal building in 1985; it now weighs about 54 tons and is the largest community folk-art piece in the world, with panels for more than 110,000 people.

Which star of Cleopatra and National Velvet served as founding national chairman of amfAR, formed in September 1985?

Elizabeth Taylor's West Coast foundation merged with Mathilde Krim's New York group to form amfAR, and in 1991 she launched her own AIDS foundation, paying its overheads herself so donations went straight to care.

Which Wimbledon champion announced in 1992 that he had contracted HIV from a transfusion during heart bypass surgery?

Arthur Ashe went public only to pre-empt a USA Today story about his illness, then founded a foundation for the defeat of AIDS before dying in 1993; the US Open's main stadium now carries his name.

Which enzyme lets HIV copy its RNA genome into DNA, the error-prone step that drives its rapid mutation?

Reverse transcriptase has no proofreading ability, so it makes errors every time it copies the genome — the reason HIV mutates so fast and why single drugs quickly lose their grip. Hepatitis B uses the same trick.

HIV-1, the pandemic strain, crossed into humans in southern Cameroon from a simian virus carried by which animal?

Chimpanzee SIV jumped the species barrier at least twice, producing HIV-1 groups M and N; only group M went pandemic, while the rare groups O and P came from gorillas and HIV-2 descends from a monkey, the sooty mangabey.

Genetic studies trace the pandemic HIV-1 strain to the 1920s in which Congo River city, then called Léopoldville?

Kinshasa's colonial railways, a million travellers a year and unsterilised clinic needles let the virus spread for decades unnoticed; a 1959 blood sample from the city holds one of the earliest known HIV infections.

In the 'U=U' message launched by the Prevention Access Campaign in 2016, an undetectable viral load means HIV is what?

Untransmittable means a person on effective treatment cannot pass HIV on sexually, a finding proven in trials of thousands of couples and endorsed by the WHO; more than 1,100 organisations in 105 countries back the message.

The multi-drug regimen unveiled at the 1996 International AIDS Conference, which made HIV survivable, has what acronym?

HAART combines drugs that hit different viral targets at once, so the virus cannot mutate around all of them; typical regimens pair two nucleoside drugs as a backbone with a third from another class.

Which AIDS researcher, a pioneer of combination antiretroviral therapy, was Time magazine's Man of the Year for 1996?

David Ho's team showed for the first time that combination therapy could durably suppress HIV replication, and his 'hit early, hit hard' approach turned a terminal diagnosis into a chronic, manageable one.

PEP, the emergency course of anti-HIV drugs taken after a possible infection, must start within what time window?

72 hours is the cut-off because after that PEP is much less effective and may not work at all; the sooner the course starts after a needle-stick or a burst condom, the better it protects.

A 32-base-pair deletion in which gene, found in roughly 1% of Europeans, gives strong resistance to HIV-1 infection?

CCR5 is the doorway HIV-1 uses to enter immune cells, and people with two copies of the deletion simply lack it; the trade-off may be greater vulnerability to some mosquito-borne and tick-borne viruses.

Which cancer, marked by purple skin lesions, was among the first illnesses tied to AIDS when cases surfaced in 1981?

Kaposi's sarcoma is caused by a herpesvirus, HHV-8, that a healthy immune system keeps in check, which is why the once-rare tumour exploded among people whose immunity had collapsed.

UNAIDS, launched in 1996 to coordinate the UN's response to HIV, is headquartered beside the WHO in which city?

Geneva's UNAIDS secretariat shares site facilities with the WHO; the programme was created by a 1994 ECOSOC resolution and traces its roots to the Global Programme on AIDS that dreamed up World AIDS Day.

Which US president launched PEPFAR in 2003, now the largest commitment by any nation to fighting a single disease?

The Global Fund, operating since 2002, bankrolls the fight against AIDS and which two other diseases?

Tuberculosis and malaria joined AIDS because together the three killed millions a year; by 2019 the fund had disbursed over $41.6 billion, financing 227 million insecticide-treated bed nets in 2018 alone.

The only HIV vaccine trial to show protection, RV 144, cut infections by 31% among 16,000 volunteers in which country?

Thailand's health ministry would only have licensed the vaccine at 50% protection, so the 31% result went nowhere — but it remains the first evidence any vaccine can lower HIV risk. Results came in September 2009.

Which twice-yearly injection, named 2024 'Breakthrough of the Year', showed 100% efficacy at preventing HIV in women?

Lenacapavir works by jamming HIV's capsid protein, and its long tissue half-life means two subcutaneous shots a year; the FDA approved it for HIV prevention, as Yeztugo, in June 2025.

Which immunologist led the US NIAID from 1984 to 2022, through the AIDS crisis and COVID-19, under seven presidents?

Anthony Fauci bore the brunt of anger from a community that felt ignored by government in the 1980s, and across seven presidencies became what one profile called a broker of 'generational peace' between science and politics.

Which scientist, who built the first HIV blood test, was named co-discoverer of the virus in a 1987 US–French deal?

Robert Gallo's 1984 'discovery' turned out to be a sample the French had sent him the year before, as he conceded in 1991, and the 2008 Nobel committee passed him over for the prize. The patent proceeds were split equally.

Which 1996 musical, based on Puccini's La Bohème, follows East Village artists living under the shadow of HIV/AIDS?

Rent won both the Pulitzer Prize for Drama and the Tony for Best Musical, though creator Jonathan Larson died of an aortic dissection the night before its first off-Broadway preview. It ran on Broadway for 12 years.

Tony Kushner's two-part play about AIDS in 1980s Manhattan, in which the lawyer Roy Cohn lies dying, is titled what?

Matthew McConaughey won an Oscar as Ron Woodroof, a Texan smuggling unapproved AIDS drugs, in which 2013 film?

Dallas Buyers Club was only the fifth film ever to win both Best Actor and Best Supporting Actor, the latter for Jared Leto as Rayon, a transgender composite character; Woodroof's story came from a 1992 magazine profile.

Which 1994 Real World cast member, an AIDS educator, did Bill Clinton credit with humanising the virus for Latinos?

Which diver hit his head on the springboard at the 1988 Seoul Olympics, then revealed in 1995 he had been HIV-positive?

Greg Louganis had been diagnosed six months before Seoul and was already on antiretrovirals; the CDC later stressed the bleeding posed no risk to other divers, since pool water dilutes blood and chlorine kills HIV.

Gaëtan Dugas, wrongly branded 'Patient Zero' of the US epidemic until a 2016 genetic study, held which job?

Flight attendant Dugas had actually been labelled 'Patient O' — the letter, for 'Out-of-California' — which a misreading turned into 'Patient Zero'; the editor of the book that vilified him later admitted it was done to spur sales.

Which British singer, having lost two friends to AIDS in a year, founded a 1992 charity known for its Oscars party?

Elton John's foundation has raised over $600 million for HIV programmes in 55 countries, and its Academy Awards party, first held in 1993, became one of Hollywood's biggest Oscar-night events.

Which rock singer co-founded the (RED) brand with Bobby Shriver in 2006 to send corporate profits to the Global Fund?

Bono first announced (RED) at the World Economic Forum in Davos with Shriver, his partner in the ONE Campaign and DATA; The Independent ran a special (RED) issue in 2006 and gave half its revenue to the Global Fund.

Which playwright co-founded Gay Men's Health Crisis and dramatised the early epidemic in 1985's The Normal Heart?
