Men who have sex with men remain the group most at risk of becoming infected with HIV.

New diagnoses in this group alone have increased by 70% in the past 10 years.

There are more than 30,000 men who have sex with men living with HIV in the UK and experts estimate nearly a third of these are currently undiagnosed and unaware that they are infected.

Another high risk group that would benefit from increased HIV testing, according to NICE, is the black African community living in England.

In 2009, more than 2,000 black Africans were diagnosed with an HIV infection; one-third of all new diagnoses in the UK.
