Yellow Fever vs. Jaundice: Key Differences Explained

Both cause yellowing of skin/eyes, but they are fundamentally different:

Feature	Yellow Fever	Jaundice
Cause	Viral infection (flavivirus) from mosquito bite	Symptom of bilirubin buildup from various underlying conditions
Transmission	Mosquito vector (Aedes/Haemagogus)	Not contagious; reflects liver/hemolytic/biliary pathology
Key Symptoms	Fever, chills, muscle aches, nausea, vomiting, jaundice, bleeding	Yellow skin/eyes, dark urine, pale stools, itching
Severity	Can be fatal (15–50% severe cases)	Depends on underlying cause

Relationship: Yellow fever can cause jaundice as a symptom, but most jaundice is not from yellow fever.

Action: Any jaundice requires medical evaluation to identify the cause. Yellow fever is a medical emergency—seek care immediately if suspected.
