A patient who is a fisherman presents with hepatitis that has been fully CURED/resolved. What type of hepatitis did this patient most likely have?
Show answer and explanation
Correct answer: A. Hepatitis A
A) Hepatitis A — CORRECT.
Hepatitis A is the ONLY common hepatitis that: (1) is fully CURED/resolved with no chronic carrier state, (2) is transmitted via fecal-oral route (contaminated water, seafood — relevant to a fisherman), and (3) provides lifelong immunity after infection. Hepatitis B (5–10%) and C (75–85%) can become chronic.
B) Hepatitis B: 5–10% of adults become chronic carriers; the clue "cured" points away from B.
C) Hepatitis C: Rarely resolves spontaneously (~15%); the majority (85%) become chronic.
D) Hepatitis D: Requires HBV co-infection; always associated with chronic disease risk.
