Annual Screening in Kathmandu
- ~70% silent — asymptomatic majority — case for screening.
- PID ~10–15% untreated — complication screen prevents.
- Annual = baseline — ~3–6 months where higher-risk.
- Curable — screening catches what treatment cures.
The Annual Chlamydia Screen — the Silent-Majority Case
The annual chlamydia screen is periodic test for sexually-active adults — justified by the ~70% asymptomatic rate: most chlamydia produces no symptoms while producing complications (PID, tubal damage, fertility consequences) that are reason to catch it.
The screen is detection that symptoms cannot provide — asymptomatic infection is only caught by periodic test; symptom-driven approach misses the ~70% entirely.
The annual is baseline for sexually-active adults — floor. Higher-risk patterns (multiple partners, unprotected, new relationships, a partner diagnosed) warrant more frequent — ~3–6 months — but annual catches silent infections even in lower-risk pattern.
Why Annual — the Silent Majority
~70% of chlamydia produces no symptoms — infection producing no warning while producing the PID (~10–15% of untreated cases), tubal damage, fertility consequences — complications that arrive silently until they are infertility or ectopic presentation.
The annual screen is detection symptoms cannot provide — asymptomatic infection found only by periodic test, before complication it produces.
~70% Silent
The asymptomatic majority — no warning signs.
PID ~10–15%
The untreated consequence — fertility damage.
Silent Complications
The damage without symptoms.
Screening the Detection
The annual test catches what symptoms cannot.
The Test — Site-Matched NAAT
The test is NAAT — ~95% on correct specimen: first-catch urine or vaginal swab for urogenital; throat swab for oral-sex exposure; rectal swab for anal — site-matched coverage year's exposure pattern determines.
The correct coverage within annual screen is complete version — a urine-only annual screen covers only urethra; site-matched covers sites year's exposure involved.
NAAT ~95%
The diagnostic standard.
Site-Matched
Urine/vaginal plus throat/rectal where warranted.
Coverage = the Screen
The specimens determine what annual covers.
Urine-Only Incomplete
The coverage gap in default.
The Frequency — Annual Floor, More Where Higher-Risk
The annual is baseline for sexually-active adults — floor. The higher-frequency applies where risk pattern warrants: ~3–6 months for multiple partners, new-relationship testing where a new partner begins, partner-diagnosed testing immediately, exposure-driven testing where a specific event occurs.
The honest interval guidance: annual plus more-frequent where pattern suggests it — not a reflexive same-frequency-for-everyone.
Annual = Baseline
The floor for sexually-active adults.
~3–6 Months Higher-Risk
Multiple partners, unprotected — more frequent.
New Relationship
The testing where a new partner begins.
Exposure-Driven
Where a specific event occurs.
The Complete Annual Pathway
The annual visit: confidential consultation ( year's exposure reviewed, correct specimens selected), site-matched NAAT, interpreted result — annual screen is complete service, not just a urine drop.
Where positive, management is at same service — antibiotic course (doxycycline preferred), partner care, follow-up — annual screen linking to complete pathway.
Confidential Visit
The exposure reviewed; specimens selected.
Site-Matched
The correct coverage for year's pattern.
Positive → Complete Care
Treatment and partner care at same service.
Interpreted
The meaning included — not just number.
