Data published today by Public Health England (PHE) reveal that new HIV diagnoses in the UK have fallen for the second year in a row. New diagnoses decreased by 17% in 2017 – from 4,363 new diagnoses reported compared to 5,280 in 2016, which brought new cases down to their lowest level since 2000.

This decrease continues a downward trend that started in 2015, with an overall 28% reduction in new HIV diagnoses between 2015 and 2017. The reduction was largely driven by a decline in new HIVdiagnoses among gay and bisexual men, which fell by 17% compared to 2016 and by 31% compared to 2015. This decrease was due to the high uptake of HIV testing in this group, particularly repeat HIVtesting among higher risk men. Increased uptake of anti-retroviral therapy (ART) – drugs that keep the level of HIV in the body low and help prevent it being passed on – also significantly contributed to the decline in new diagnoses.

New HIV diagnoses in black African and Caribbean heterosexuals have been steadily decreasing over the past 10 years. For the first time, a UK-wide fall was also seen in new diagnoses in heterosexuals from other ethnicities, with a drop of 20% in 2017 when previously they had remained stable at around 1000 per year.

Professor Noel Gill, Head of the STI and HIVDepartment at Public Health England, said:

We are pleased to see that UK prevention efforts are having a significant impact on new HIV diagnoses, and this heralds the lowest number of HIV diagnoses in the UK since 2000. However, we know that anyone who has sex with a casual partner without a condom or shares needles may be at risk of infection.
