Sexual health services in England are "at a tipping point", according to local councils in England, who say visits to clinics have increased while funding has been cut.
The Local Government Association warns that patients could face longer waiting times.
Chlamydia is the most common STI in the UK and is easily passed on during sex. It can be tested for by providing a urine sample or a vaginal swab. The latest data shows diagnoses of sexually transmitted infections (STIs) have fallen in the past year. This is due to the UK's investment in wide spread screening programs. These services are now being cut, when they are shown to be effective.
Responsibility for public health in England has rested with local councils since 2013 - but the Local Government Association says it has not been given adequate resources to run proper services.
Council leaders say it is good news more people are taking responsibility for their sexual health, but they warn that higher numbers are turning up at clinics and putting a strain on resources.
The LGA says patients could face a poorer quality service and wait longer for tests and treatment if additional funding is not provided.
Cllr Izzi Seccombe, chairman of the LGA's Community Wellbeing Board, said: "The reduction in public health funding could also compound problems further and impact on councils' ability to meet demand and respond to unforeseen outbreaks."
