The number of sexually transmitted infections in the city increased last year.

Figures from the UK Health Security Agency show there were 4,476 STI diagnoses in Brighton and Hove – up from 3,149 the year before.

Of these, 2,300 (51 per cent) were chlamydia.

There were 813 gonorrhoea diagnoses in Brighton and Hove in 2023, up from 762 cases the year before.

Meanwhile, syphilis diagnoses remained the same at 149 cases last year.

The British Association for Sexual Health and HIV (BASHH) said the "worrying trajectory" of rising diagnoses of sexually transmitted infections across England is a sign of unmet needs for those who require sexual health care.

Nationally, recorded cases of syphilis were at the highest level since 1948, while gonorrhoea reached the highest number since records began in 1918.

Professor Matt Phillips, president of BASHH, said: "We find ourselves at a critical point for securing the viability of sexual health services.

"The worrying trajectory of new STI diagnoses is a sign of increased unmet needs for those who require sexual health care, particularly those in minoritised communities and those who might prefer face-to-face services.

"It underlines the need for a long-awaited and much-needed strategy for sexual health."

He said the new government has an opportunity to "change the tides "and address recruitment and funding challenges to improve access to sexual health and wellbeing expertise.

The Local Government Association, which represents councils with responsibility for commissioning sexual health services, said the figures show the government should implement a ten-year sexual health strategy.

Richard Angell, chief executive of sexual health service provider Terrence Higgins Trust, said the figures show a year-on-year increase of STIs and demand for services.

He added the government must commit to a national strategy and funding that "sets a clear direction for improving sexual health in England".

Dr Hamish Mohammed, consultant epidemiologist at the UKHSA, said: "The best way to reduce your risk of an infection is to use a condom consistently and correctly with new or casual partners.

"The NHS provides free, confidential STI testing to detect any potential infections and prevent you passing them on to others."
