Major contributor to chronic hepatitis leading to chronic disease?

Appeared in: NORCET 9 Mains - 2025

Explanation

Hepatitis B (HBV) and Hepatitis C (HCV) are the two primary viruses that lead to chronic liver disease.
Hepatitis C is particularly known for its high rate of chronicity, with over 80% of infected individuals developing a long-term infection.
Hepatitis B also has a significant risk of becoming chronic (5-10% in adults), especially when infection occurs in infancy or childhood.
Both HBV and HCV are major causes of subsequent cirrhosis and hepatocellular carcinoma (liver cancer).

Option A: Hepatitis A virus (HAV) does not cause chronic liver disease; it is an acute, self-limiting infection.
Option B: This option is incorrect because Hepatitis A (HAV) only causes acute hepatitis and does not lead to chronic disease.
Option C: This option is incorrect because Hepatitis A (HAV) is not a cause of chronic hepatitis. It is an acute infection.

Clinical Relevance

Nursing practice connection: Knowing Etiology of Chronic Viral Hepatitis helps nurses interpret findings accurately and avoid errors in routine assessment, medication administration, and patient teaching.
Nurses play a crucial role in educating patients about the transmission routes of different hepatitis viruses to prevent spread.
For patients with chronic hepatitis B or C, nursing care involves monitoring liver function tests, assessing for complications like ascites or encephalopathy, and providing education on medication adherence and lifestyle modifications (e.g., avoiding alcohol).
What if? If a patient with chronic hepatitis B becomes superinfected with Hepatitis D, the nurse should anticipate a much more rapid progression to cirrhosis and liver failure, requiring more intensive monitoring and management.

How to Approach the Question

First, identify the core concept of the question, which is 'chronic hepatitis'.
Recall the characteristics of the different hepatitis viruses (A, B, C, D, E).
A key piece of knowledge is that Hepatitis A and E are transmitted via the fecal-oral route and cause acute, not chronic, illness (with rare exceptions for HEV in the immunocompromised).
This knowledge allows you to immediately eliminate any option that includes Hepatitis A (Options A, B, and C).
This leaves only Option D. Confirm that both Hepatitis B and C are well-known causes of chronic hepatitis, making this the correct answer.
