There have been many medical advances in the 30 years since HIV was first identified, but stigma remains the biggest barrier to people around the world accessing life-saving treatment.
Christian Aid and Magnum Photos created a series of thought-provoking audio-photographic slideshows for World AIDS Day - Stigma Under the Lens.
Stigma Under the Lens was shortlisted in the new media category of the One World Media Awards 2012.
The galleries tell the stories of brave people around the world who are living with HIV under the shadow of stigma.
They examine how stigma manifests itself in everyday life, and go some way to explaining why thousands of people would rather not know their status than face discrimination at home, in their community, at work and within their faith.
Watch, hear and explore testimonies of discrimination by friends, family and society at large in Kenya, Bolivia, Tajikistan, India and right here in the UK.
