HIV in the UK

  • More than 102,000 people in the UK are HIV positive. 94,000 are diagnosed and 8,000 do not know they have HIV.
  • Over 98% of people who are diagnosed are on treatment which makes HIV difficult to transmit.
  • 1.5 million people take an HIV test each year. Half are in a sexual health setting and half in pregnancy screening. More than 99% of all results are negative.
  • Of the roughly 4,300 people who tested positive last year (less than 0.5% of all tests), half are heterosexual and half are gay men.
  • Half of diagnoses are late: ie in people who are likely to have been HIV positive for many years.
  • Late diagnosis causes half of all HIV-related deaths. These could be prevented with earlier testing.
