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.
