**Question:** Fulminant hepatitis is commonest with

A. Hepatitis A
B. Hepatitis B
C. Hepatitis C
D. Hepatitis E

**Correct Answer:** D. Hepatitis E

**Core Concept:** Hepatitis E is a viral infection primarily caused by the Hepatitis E virus (HEV). It is a significant cause of acute hepatitis worldwide, especially in endemic regions.

**Why the Correct Answer is Right:** Hepatitis E is a significant cause of acute hepatitis, particularly in endemic regions where sanitation and hygiene are poor. The infection is transmitted through the fecal-oral route, thus making it more common in areas with inadequate sanitation and contaminated water sources. In fulminant hepatitis, rapid and severe liver damage occurs, which is more common in patients with underlying liver disease or immune compromised individuals. Hepatitis E is known to cause severe hepatitis, especially in pregnant women, leading to a higher incidence of fulminant hepatitis as compared to other types of hepatitis viruses.

**Why Each Wrong Option is Incorrect:**

A. Hepatitis A: While hepatitis A can cause severe hepatitis, it is less common to present as fulminant hepatitis.

B. Hepatitis B: Although Hepatitis B can cause fulminant hepatitis, it is less common compared to Hepatitis E.

C. Hepatitis C: Hepatitis C is less likely to present as fulminant hepatitis compared to Hepatitis E, especially in the context of poor sanitation and hygiene.

**Clinical Pearl:** Hepatitis E is an essential differential diagnosis to consider in patients presenting with acute hepatitis, especially in endemic regions. It is crucial to investigate for Hepatitis E virus in such cases to initiate appropriate management and preventive measures for the patients and the community.
