* HIV.B.DE228: Vaginal discharge syndrome | Client diagnosed with vaginal discharge syndrome
* HIV.B.DE229: Lower Abdominal pain | Client diagnosed with lower abdominal pain
* HIV.B.DE230: Genital ulcer disease syndrome | Client diagnosed with genital ulcer disease syndrome
* HIV.B.DE231: Anorectal discharge | Client diagnosed with anorectal discharge
* HIV.B.DE232: Sent for testing | Specimen sent for testing
* HIV.B.DE233: Other | Other syndrome/STI diagnosed
* HIV.B.DE235: Any STI syndrome diagnosed | Was the client diagnosed with any of the five STI syndromes during this visit?
* HIV.D.DE778: Syndrome/STI diagnosed | Syndrome or STI for which client is diagnosed
* HIV.D.DE779: Urethral discharge syndrome | Client diagnosed with urethral discharge syndrome
* HIV.D.DE780: Vaginal discharge syndrome | Client diagnosed with vaginal discharge syndrome

* HIV.E.DE114: Key population member type* | The type of key population that the infant's mother is included in
* HIV.E.DE115: Sex worker | Infant's mother is a sex worker
* HIV.E.DE116: People who inject drugs | Infant's mother is a person who injects drugs

* HIV.SRV.DE15: Visit date | The date and time of the client's visit
*
* Additional Context
* - what it measures: A: % of people attending HIV prevention services who were diagnosed with the same STI | syndrome two or more times during the reporting period | B: % of people living with HIV who were diagnosed with the same STI syndrome two or more times during the reporting period
* - rationale: Presenting with the same STI syndrome two or more times in a short period suggests that an individual was not treated appropriately, has an untreated partner or is practicing unsafe sex.
* - method: Individual-level data obtained from programme records
*
* Suggested Scoring Method: proportion | http://hl7.org/fhir/us/cqfmeasures/StructureDefinition/proportion-measure-cqfm
THE DEFINITION IS INCONSISTENT WITH THE CONTEXT - no mention of HIV prevention services.
