A 42-year-old man experiences malaise and increasing icterus for 2 weeks. Physical examination shows jaundice, but there are no other significant findings. Serologic test results are positive for IgM anti-HAV and negative for anti-HCV, HBsAg, and IgM anti-HBc. Which of the following outcomes is most likely to occur in this man?

**Core Concept**
The patient is experiencing symptoms of hepatitis A, an acute liver infection caused by the hepatitis A virus (HAV). The presence of IgM anti-HAV antibodies indicates a recent infection, while the absence of HBsAg, anti-HBc, and anti-HCV antibodies suggests that the patient is not infected with hepatitis B or C viruses.

**Why the Correct Answer is Right**
The patient is likely to experience a self-limiting illness with spontaneous recovery. Hepatitis A virus is primarily transmitted through the fecal-oral route and causes an acute, non-chronic infection. The liver inflammation usually resolves within 2-6 months, and the patient will likely regain normal liver function.

**Why Each Wrong Option is Incorrect**
**Option A:** This option is incorrect because hepatitis B infection typically presents with HBsAg positivity, which is not seen in this patient. Additionally, hepatitis B infection often leads to chronic liver disease, which is not indicated in this acute presentation.

**Option B:** This option is incorrect because hepatitis C infection is typically asymptomatic and may not present with jaundice. The patient's serologic test results are negative for anti-HCV, which makes this option unlikely.

**Option C:** This option is incorrect because fulminant hepatic failure is a rare complication of hepatitis A infection. The patient's presentation is consistent with acute hepatitis A, and there is no indication of fulminant liver failure.

**Clinical Pearl / High-Yield Fact**
Hepatitis A virus is primarily transmitted through the fecal-oral route, often through contaminated food or water. The risk of transmission can be reduced by proper hand hygiene, safe food handling, and vaccination.

**Correct Answer:** **D**. The patient is likely to experience a self-limiting illness with spontaneous recovery.

✓ Correct Answer: B. Complete recovery
