Chlamydia was the most common STI, making up 47% of all diagnoses (208,755), while gonorrhoea diagnoses saw a large rise, up 15% from 2012 to 2013 (29,291).
Dr Catherine Lowndes, consultant scientist in PHE’s STI surveillance team said: “Chlamydia can have serious consequences, including infertility, if it’s not treated.
“This data shows we need to do more to encourage young adults to ask for testing every year when they attend health services.”
