The most recent estimate (2019) suggests there were just over 100,000 people living with HIV in the UK, including more than 5,000 undiagnosed people who are HIV positive.
People living in London, men who have sex with men, and black African people are disproportionately affected:
22% of people with new diagnoses in England in 2021 were living in London
of the 2,023 people diagnosed in England in 2021, 36% were gay or bisexual men
of the 798 heterosexual people diagnosed with HIV in England in 2021, 37% were black African men and women.
