Events to mark World AIDS Day were staged across the region yesterday, hoping to raise awareness of the spread of HIV.
More than 35 million people have died from the virus world-wide, making it one of the most destructive pandemics in history.
Andy Dickenson visited the Sussex Beacon care centre in Brighton and spoke to HIV sufferers David Fray and Ian Wallace, as well as Tabitha Morrison, Clinical Medical Officer.

It can be caught by anyone - regardless of their gender, race or sexuality. And that's very much the message of a new photographic exhibition which is bringing together people who're HIV positive - from all walks of life.
Charlotte Wilkins has been speaking to Photographer Edo Zollo; David Fray and Mandy Webb who are both living with HIV; and Simon Dowe from the Sussex Beacon.
