Typical Course of Hepatitis B Virus Acute Chronic Model
Product Code : JC-BE-6240
The Typical Course of Hepatitis B Virus Acute Chronic Model from Jaincolab is an educational chart comparing the timeline of key serological markers across an acute, self-resolving Hepatitis B virus (HBV) infection versus one that progresses to chronic infection. The model plots how markers such as HBsAg, HBeAg, anti-HBc (IgM and IgG), anti-HBe and anti-HBs rise and fall over time, showing the marker pattern that indicates recovery and immunity versus the pattern seen in chronic carriers.
As a trusted biology lab equipment supplier in India, Jaincolab designs this model to help students of microbiology, virology and clinical pathology interpret HBV serology correctly, a skill essential for diagnosing infection stage, monitoring patients and counselling on infectivity, supporting classroom teaching and laboratory demonstration in clinical microbiology courses.
What the Concept States
| Parameter | Details |
|---|---|
| Virus | Hepatitis B Virus (HBV) — enveloped, partially double-stranded DNA virus (Hepadnaviridae) |
| HBsAg (Hepatitis B surface antigen) | First marker to appear; persists through acute infection and, if present beyond 6 months, indicates chronic infection |
| Anti-HBc IgM | Appears early in acute infection and indicates recent infection; the key marker distinguishing acute from chronic infection during the 'window period' |
| HBeAg | Marker of active viral replication and higher infectivity; its disappearance (seroconversion to anti-HBe) generally signals reduced replication |
| Anti-HBs (surface antibody) | Appears after HBsAg clears in a resolving acute infection, indicating recovery and long-term immunity; also the marker induced by vaccination |
| Window Period | The interval after HBsAg disappears and before anti-HBs appears, during which anti-HBc IgM may be the only detectable marker of infection |
| Chronic Infection Pattern | HBsAg persists beyond 6 months without anti-HBs development, often with fluctuating HBeAg/anti-HBe and HBV DNA levels reflecting ongoing viral activity |
Key Features
- Clear timeline comparison of HBV serological markers in acute resolving versus chronic infection
- Highlights the diagnostically important 'window period' where anti-HBc IgM may be the only positive marker
- Connects marker patterns to clinical interpretation: recovery and immunity versus chronic carrier state
- Durable, classroom- and laboratory-ready construction suitable for repeated use in practical sessions
- Supports microbiology, virology, clinical pathology and hepatology curricula
- Practical companion to serology-based diagnostic training in clinical laboratories

Frequently Asked Questions
Q1. What does the Typical Course of Hepatitis B Virus Acute Chronic Model illustrate?
A. It illustrates the timeline of key HBV serological markers, including HBsAg, HBeAg, anti-HBc, anti-HBe and anti-HBs, comparing the pattern seen in acute resolving infection with the pattern seen when infection becomes chronic.
Q2. What is the 'window period' shown in this model?
A. The window period is the interval after HBsAg has cleared but before anti-HBs has appeared, during which anti-HBc IgM may be the only detectable serological evidence of HBV infection.
Q3. How does the marker pattern differ between acute and chronic HBV infection?
A. In acute resolving infection, HBsAg clears and anti-HBs develops, indicating recovery and immunity, whereas in chronic infection HBsAg persists beyond six months without the appearance of protective anti-HBs.
Q4. Is this model suitable for medical and paramedical teaching?
A. Yes, the model is designed to support clinical microbiology, virology and hepatology curricula at medical and paramedical college level.
Q5. Can Jaincolab supply this along with other virology and microbiology teaching models?
A. Yes, Jaincolab supplies this model alongside a full range of virology, microbiology and clinical pathology teaching aids for biology laboratories across India and internationally.
