Hepatitis B in Kathmandu
- Chronic carriage silent — decades of asymptomatic infection.
- HBsAg detection — surface antigen detects current infection.
- Staged before management — viral load, ALT, e-antigen determine stage.
- Vaccine ~95% effective — prevention; does not treat existing carriage.
Hepatitis B — the Silent Chronic Infection
Hepatitis B is chronic-carriage viral hepatitis — silent for decades while producing cirrhosis and hepatocellular carcinoma that are severe outcomes — detectable by surface antigen (HBsAg) and managed (not usually cured, but controlled) by monitoring or antiviral suppression.
The carrier state is relevant picture: most HBV infections in adults are cleared; a fraction become chronic — carrier who is asymptomatic, transmissible, and on path to liver damage without knowing. The HBsAg test is detection; staging (viral load, ALT, e-antigen) determines management.
The vaccination is prevention — ~95% effective at producing immunity — with honest caveat that vaccination prevents future infection but does not treat an existing carrier state; screening and vaccination are two separate interventions.
The Testing — HBsAg & the Panel
The screening marker is HBsAg (hepatitis B surface antigen) — a positive indicates current infection. The fuller panel distinguishes pictures: surface antibody (immunity from vaccination or resolved infection), core antibody (past or current infection marker), e-antigen (replication activity) — components that stage disease.
A positive HBsAg is chronic carriage — patient is an asymptomatic carrier with transmissibility and long-term risk — requiring staging that determines management.
HBsAg
Current HBV infection — screening marker.
Panel Distinguishes
Resolved, vaccinated, active carrier — fuller picture.
Chronic Carriage
Asymptomatic, transmissible — silent infection.
Staging Follows
The viral load, ALT, e-antigen determined.
Staging — the Carrier State Assessed
The staging distinguishes carrier states: immune-tolerant (high viral load, normal ALT — monitored, not treated), immune-active (raised ALT — treatment indication), inactive carrier (low viral load, normal ALT — monitored), and reactivation risk states. The stage determines whether treatment is indicated or monitoring suffices.
The viral load and the ALT pattern drive decision — carriers who need antiviral suppression are identified by staging, not by symptoms (which are absent until advanced).
Immune-Tolerant
High viral load, normal ALT — monitored.
Immune-Active
Raised ALT — treatment indication.
Inactive Carrier
Low viral load, normal ALT — monitored.
Stage = Management
Treat or monitor — staging decides.
Management — Controlled, Not Cured
HBV is managed, not usually cured — antiviral suppression (tenofovir, entecavir) controls viral replication, reducing cirrhosis and cancer risk, without eliminating virus. The carriers on suppression are monitored for response and long-term control.
The monitoring is lifelong — carrier state is chronic — with viral load, ALT and periodic liver assessment (ultrasound for hepatocellular carcinoma surveillance where risk warrants) ongoing management.
Suppression Controls
Tenofovir/entecavir — viral replication controlled.
Not Usually Cured
Managed — virus persists under control.
Lifelong Monitoring
Viral load, ALT — ongoing.
HCC Surveillance
Ultrasound where cancer risk warrants.
Prevention — the Vaccination Context
The HBV vaccine is ~95% effective — three doses producing protective surface antibody — prevention that matters for partners and contacts of a carrier, and routine protection where vaccine status is unknown.
The honest framing: vaccination prevents future infection — it does not treat an existing carrier — so carrier's partner is vaccinated (protection) while carrier is managed ( suppression).
Vaccine ~95%
Three doses — protective immunity.
Partner Vaccinated
The protection for partner of a carrier.
Prevents, Not Treats
The vaccine does not treat existing carriage.
Routine Where Unknown
The vaccination where status is unconfirmed.

Frequently Asked Questions
Is hepatitis B curable?
Managed — suppression controls it; chronic carriage is monitored or treated by stage.
What does a positive HBsAg mean?
Current infection — staged by viral load, ALT and e-antigen for management picture.
Is vaccine effective?
~95% — three doses produce protective immunity; it prevents, does not treat existing carriage.
Is HBV contagious?
Yes — blood and sexual contact; partner is vaccinated and carrier managed.
Do all carriers need treatment?
No — stage determines; some are monitored, others get suppression.
Is it confidential?
Yes — private testing and management.
