• A. Intestinal parasite
• B. Hepatitis A
• C. Toxoplasmosis
• D. Cirrhosis

Answer: (B)

When you see dark urine and clay-colored stools together after travel, think of acute hepatitis affecting the liver’s ability to process bilirubin. This pattern points to hepatitis A as the likely cause. Hepatitis A is a viral infection often acquired via contaminated food or water during travel, and it commonly presents with malaise, loss of appetite, and fatigue. The liver’s injury impairs bile production and excretion, so bilirubin builds up and is excreted in urine (dark urine) while bile pigments aren’t reaching the gut (pale, clay-colored stools). Other options don’t fit the pattern as well. An intestinal parasite can cause GI symptoms, but it wouldn’t typically produce this clear bile-related stool color change. Toxoplasmosis usually presents with flu-like symptoms or, in certain populations, specific organ involvement rather than this cholestatic picture. Cirrhosis is a chronic condition with signs such as ascites, spider angiomas, and progressive liver failure, not an acute travel-related presentation.
