All diagnoses of first episode genital warts among people accessing sexual health services* in England who are also residents in England, expressed as a rate per 100,000 population. Data is presented by area of patient residence and include those residents in England and those with an unknown residence (data for those residents outside of England is not included).
Rationale
Genital warts are the third most commonly diagnosed sexually transmitted infection (STI) in the UK and are caused by infection with specific subtypes of human papillomavirus (HPV). Recurrent infections are common with patients returning for treatment.
Definition of numerator
The number of diagnoses of first episode genital warts among people accessing sexual health services in England who are also residents in England.
Episode Activity codes (SNOMED or Sexual Health and HIV Activity Property Types (SHHAPT)) relating to diagnosis of first episode of genital warts were used. The clinical criteria used to diagnose the condition are given at BASHH guidelines.
Data was de-duplicated to ensure that a patient only received a diagnostic code once for each episode. Patients cannot be tracked between services and therefore de-duplication relies on patient consultations at a single service.
Definition of denominator
The denominators for 2012 to 2022 are sourced from Office for National Statistics (ONS) population estimates based on the 2021 Census.
Population estimates for 2023 were not available at the time of publication – therefore rates for 2023 are calculated using estimates from 2022 as a proxy.
Further details on the ONS census are available from the ONS website.
Caveats
Every effort is made to ensure accuracy and completeness of GUMCAD data, including web-based reporting with integrated checks on data quality. However, responsibility for the accuracy and completeness of data lies with the reporting service.
Data is updated on an annual basis due to clinic or laboratory resubmissions and improvements to data cleaning. Data may differ from previous publications.
Figures reported in 2020 and 2021 are notably lower than previous years due to the disruption to SHSs during the national response to the COVID-19 pandemic.
