 "summary": "New diagnoses of sexually transmitted infections (STIs) in England each year since 2016, in all and for chlamydia, gonorrhoea, infectious syphilis, genital herpes and genital warts, with the rate per 100,000 people, from UKHSA's annual STI data tables.",

 "status": "Official statistics",
 "notes": [
  "New diagnoses at sexual health services in England, of people living in England, by the infection diagnosed, as UKHSA counts them; the figures for all gender identities include people whose gender identity is neither man nor woman.",
  "Table 1a gives 11 infections; the chart shows the five named here and the total, which counts every one of them.",
  "Table 1b gives England the same population for 2025 as for 2024, so UKHSA's rates for 2025 rest on 2024's population, as its notes say."
