Fulminant hepatitis A in a robust adult: a case report of acute liver failure requiring urgent living donor liver transplantation

Hepatitis A virus (HAV) infection is generally a self‑limited disease; however, in adults it can rarely progress to acute liver failure (ALF), a rapidly evolving and potentially fatal condition. Although HAV‑related ALF occurs in <1% of the general adult population, the incidence may rise to about 10% in hospitalized or severe cases, with reported outcomes of 55% recovered, 31% transplanted, and 14% died. Early recognition, rapid prognostic assessment, and timely referral to a transplant center are essential because deterioration can occur abruptly and unpredictably.
