Millions of people around the world will come together today to celebrate World Aids Day.
After 30 years of fighting the virus around 90,000 people live with it in the UK, according to Public Health England.
Last year, some 6,000 people were diagnosed with HIV in the UK, with almost half (43%) of all new cases in London.
Despite decades of high-profile campaigns to educate the public about HIV/Aids, a YouGov study shows that many people in Britain still believe damaging myths, such as it being possible to catch the virus from kissing or sharing a toothbrush.
To dispel common misconceptions, two people living with the virus share their stories:
Annmarie Byrne, 68, from London
Annmarie is part of the first generation to grow old with HIV. She caught the virus from her husband in the 1990s when they were both living in Zimbabwe, and a diagnosis was seen as certain death.
When her husband died of Aids in 1996, Annmarie lived alone with the virus for decades, dealing with the isolation it can bring as well as the physical symptoms.
Thomas Lange, 49, from Brixton
Thomas was diagnosed at the tender age of 18, and spent the first six years nursing a dying partner.
The German-born former hotel worker says he feels lucky to be alive because all his gay friends from the era when HIV/Aids first emerged who got infected are now dead.
Going without treatment until 2007, Thomas now has HIV-related dementia, kidney failure and does not feel sensations from the waist down or in parts of his arms.
