Annual Screening in Kathmandu
- Most viral hepatitis silent — asymptomatic carriage — case for screening.
- Silent progression to cirrhosis — damage without symptoms.
- Annual = at-risk baseline — periodic screen where risk applies.
- Caught early, managed early — intervention before damage.
The Annual Hepatitis Screen — the Silent-Carriage Case
The annual hepatitis screen is periodic check for at-risk — justified by silent-carriage reality: most chronic HBV and HCV produce no symptoms while producing liver damage ( fibrosis progressing to cirrhosis) that is reason to catch it early.
The screen is detection that symptoms cannot provide — asymptomatic carriage is only caught by periodic test; symptom-driven approach misses silent majority entirely.
The annual is baseline for at-risk ( past exposure, higher-risk pattern, healthcare workers, household contacts of a positive) — periodic screen catching silent carriage before damage.
Why Annual — the Silent Carriage
Most chronic hepatitis is silent — the HBV and the HCV producing no symptoms while producing progressive liver damage — fibrosis advancing to cirrhosis before symptoms appear. The asymptomatic carriage is commonest presentation of chronic disease.
The annual screen is detection symptoms cannot provide — silent carriage found only by periodic test, before damage it produces.
Most Silent
The asymptomatic carriage — no warning signs.
Silent Progression
The fibrosis → cirrhosis — without symptoms.
Screen = the Detection
The annual test catches what symptoms cannot.
Early Is the Intervention
The detection while it is still manageable.
The Tests — HBsAg & Anti-HCV → RNA
The annual screen is two serologies: the HBsAg (the HBV surface antigen — current-infection marker) and anti-HCV (the HCV exposure antibody — positive → the RNA for active-vs-cleared distinction, ~25–30% self-clear).
The window honesty applies — serology detects established infection; a very recent exposure produces inconclusive until seroconversion — periodic screen at right interval being reliable detection.
HBsAg
Current HBV — carriage detected.
Anti-HCV → RNA
Exposure antibody → RNA for active-vs-cleared.
Two-Step for HCV
The antibody plus the RNA — correct sequence.
Window Applies
The seroconversion timing — periodic screen at right interval.
The Frequency — Annual for the At-Risk
The annual is baseline for at-risk: past exposure (a known exposure event — screen at correct interval), higher-risk patterns ( injection-drug use, multiple partners, dialysis or healthcare-exposure), household contacts of a positive, and routine screening where status is unknown.
The honest interval guidance: annual where ongoing risk applies; exposure-driven where a specific event occurred ( screen at correct interval — not reflexively same-day for a very recent event).
Annual = At-Risk Baseline
The periodic screen where risk applies.
Exposure-Driven
The specific-event testing at correct interval.
Higher-Risk More Frequent
The pattern determining interval.
Unknown Status = Screen
The never-tested — baseline check.
After the Screen
A positive is managed at same service — HBsAg staged for chronic-carriage picture ( suppression or monitoring by stage), anti-HCV confirmed by RNA then to curative DAA pathway (~8–12 weeks, ~95%+ SVR12 cure) — detection linking to management.
A negative is interpreted — honest read against window — with retest guidance where exposure was recent or vaccination where the HBV-negative is vaccine candidate.
HBV → Staged/Managed
The chronic-carriage picture — managed.
HCV → Cure
~8–12 week DAA — ~95%+ SVR12.
Negative → Interpreted
Read against window honestly.
HBV-Negative → Vaccinate
The ~95% vaccine where status is negative.

Frequently Asked Questions
Should I get an annual hepatitis test?
Where risk applies — past exposure, higher-risk pattern, unknown status — periodic screen catches silent carriage.

HBsAg (current HBV) and anti-HCV ( exposure antibody → RNA for active).
Is hepatitis C curable?
Yes — ~8–12 week DAA, ~95%+ cure.
Is it confidential?
Yes — private testing and results.
