An initiative in Exeter this week is making it easy for people to get tested for HIV.
There's concern that 24 per cent of people with the condition don't know they have it - and many who know they're at risk don't realise that HIV is now a treatable illness.
All this week, testing sessions are taking place at the Exeter sexual health clinic in the evenings - people don't need an appointment and can request a no-questions-asked test.
