■There are around 4,300 young people under 19 who are infected in the UK.
■Over a quarter of people living with HIV do not know they are infected
■ An estimated 96,000 (90,800-102,500) people were living with HIV in the UK by the end of 2011 (an increase from 91,500 (85,400-99,000) in 2010)
■The overall prevalence in 2011 was 1.5 per 1,000
■The population with the highest rates reported among men who have sex with men (MSM) (47 per 1,000) and the black African community (37 per 1,000).
■24% (19%-28%) of people living with HIV are unaware of their infection in 2011, the same proportion as seen in 2010.
■In 2011, 6,280 people were newly diagnosed with HIV in the UK, a 21% decline from the peak in new diagnoses in 2005. The decrease is largely due to a reduction in the number of diagnoses reported among those born outside of the UK.
