Sexually transmitted infection screening and management

Also known as STI screening in adolescents · Sexually transmitted infection testing · Chlamydia and gonorrhoea screening · Adolescent sexual health screening · 5 P's sexual history · STI treatment in young people · Expedited partner therapy

A fellowship approach to confidential, youth-friendly STI care in adolescents: time alone and conditional confidentiality, the 5 P's sexual history, risk- and anatomy-based screening (universal CT/GC for sexually active females under 25, selective extragenital testing, syphilis/HIV by risk), syndrome recognition, guideline-based treatment with local-dose verification, partner services and expedited partner therapy, ~3-month rescreening, and prevention across ANZ, UK, US and Canada.

The fellowship answer

STI care in an adolescent is a confidential encounter that turns history into the right test, the right treatment and the right follow-up. Start with time alone and conditional confidentiality. Take a structured 5 P's sexual history (Partners, Practices, Protection, Past history, Pregnancy intention). Then screen by risk and anatomy, not by gender assumption: universal chlamydia/gonorrhoea for sexually active females under 25, extragenital NAAT when oral or anal exposure is disclosed, and syphilis/HIV by risk. Treat per current guideline while you verify the local dose, test for pregnancy before any tetracycline, arrange partner services, and rescreen at about 3 months. If the young person is unsafe today — severe pelvic inflammatory disease, pregnancy, suspected coercion — stop the routine and escalate. [1] [3] [19]

Overview & Definition

A 16-year-old asks you for "the check." You order a urine test, pronounce her "clear," and move on. You never created private time, never asked about partners or coercion, and never sampled the rectal or pharyngeal sites her history would have revealed. Three months later she returns with pelvic inflammatory disease. The missed work was not a rare pathogen. It was an STI visit without a youth-friendly process. [19] [13]

Sexually transmitted infection (STI) screening means testing asymptomatic people whose age, anatomy, practices or exposures put them at risk. It is distinct from diagnostic testing, which is triggered by symptoms, signs or a known exposure. This distinction changes the conversation: screening is opportunistic prevention; diagnostic workup is clinical problem-solving. [1] [4]

STI management spans recognition, investigation, treatment, partner services, rescreening and prevention. For an adolescent, every step is mediated by confidentiality, capacity and access. The clinical skill is not memorising a regimen. It is running a confidential, non-judgemental encounter that surfaces the truth, samples the right sites, treats correctly and brings the young person back. [3] [19]

Screening is for the well; diagnosis is for the symptomatic

Universal chlamydia and gonorrhoea screening targets sexually active females under 25 precisely because most are asymptomatic and will not declare themselves through illness. If you wait for symptoms, you have already lost the chance to prevent pelvic inflammatory disease and infertility. [1] [16]

Core sequence of an adolescent STI encounter

  1. 1

    Engage in private

    Greet the young person first, set a joint agenda, create time alone, state conditional confidentiality.

  2. 2

    5 P's history

    Partners, Practices, Protection, Past STI, Pregnancy intention — plus a coercion check.

  3. 3

    Risk-stratify and examine

    Decide sites by anatomy and exposure; offer chaperoned exam or self-collection.

  4. 4

    Screen or diagnose

    NAAT by site, syphilis/HIV serology by risk, pregnancy test before treatment.

  5. 5

    Treat + partner services

    Guideline regimen, pregnancy-aware; expedited partner therapy where lawful.

  6. 6

    Rescreen + prevent

    Retest at ~3 months, layer condoms/HPV vaccine/PrEP/contraception, safety-net.
