The number of gonorrhoea and syphilis diagnoses was the highest on record last year, new figures show.
Annual figures from the UK’s Health Security Agency (UKHSA) show gonorrhoea diagnoses increased to 82,592 in 2022, an increase of 50.3% compared with 2021 (54,961).
This is the highest number of diagnoses in any one year since records began in 1918, the UKHSA said.
Data from the health body also shows that infectious syphilis diagnoses increased to 8,692 in 2022, the largest annual number since just after the Second World War.
People aged between 15 and 24 years are the most likely to be diagnosed with sexually transmitted infections (STIs) due to changing sexual partners more often than other age groups.
‘More gonorrhoea diagnoses than ever before’
Dr Hamish Mohammed, consultant epidemiologist at UKHSA, said: “We saw more gonorrhoea diagnoses in 2022 than ever before, with large rises, particularly in young people. STIs aren’t just an inconvenience – they can have a major impact on your health and that of any sexual partners.
“Condoms are the best defence, but if you didn’t use one the last time you had sex with a new or casual partner, get tested to detect any potential infections early and prevent passing them on to others. Testing is important because you may not have any symptoms of an STI.”

New test to diagnose ‘the most common STI you’ve never heard of’
Though STIs are usually easily treated with antibiotics, some can cause serious health issues including infertility and pelvic inflammatory disease.
The UKHSA has urged people to use condoms and get tested regularly if having sex with new or casual partners.
Syphilis is a bacterial infection that is usually caught by having sex with someone who is already infected. It can be treated with antibiotics, but if left untreated can cause serious long-term problems.
In 2022, there were 2,195,909 diagnostic tests for chlamydia, gonorrhoea, syphilis or HIV – 13.4% more than 2021.
The UKHSA said that while the rise in gonorrhoea and syphilis diagnoses will partly be due to increases in testing, the sharp rise “strongly suggests” there is more transmission of STIs in the population.
