HIV infection has been transformed from a fatal to chronic life-long infection due to the introduction of effective antiretroviral therapy (ART) in the mid-1990s. Consequently, the number of people living with diagnosed HIV has risen year on year, with an increase in number of new diagnoses among men who have sex with men (MSM) and people born in high prevalence countries.
By the end of 2011, an estimated 96,000 (95% credible interval 90,800 – 102,500) people were living with HIV in the UK; approximately one quarter (22,600, 24% [19%- 28%]) of whom were undiagnosed and unaware of their infection. This is an increase from the 91,500 people estimated to have been living with HIV by the end of 2010. The estimated prevalence of HIV in 2011 was 1.5 per 1,000 (1.5-1.6) population of all ages, 2.1 per 1,000 (1.9 – 2.3) men and 1.0 per 1,000 (1.0 – 1.1) women.
