Mr Durkan said: “I am delighted to support World Aids Day and this important campaign which aims to halve the proportion of people diagnosed late with HIV.
“Around a quarter of people who have HIV are still undiagnosed and thus far more likely to pass the virus on.
“I would therefore encourage those most at risk to take a test.
“It is fast and simple – and one of the best weapons we have to stop the spread of HIV.
“Indeed, early testing of HIV not only saves lives but also results in substantial savings to the public health budget,” added the Foyle MP.
