Sylvatic yellow fever

This code represents a severe, acute viral hemorrhagic disease transmitted by mosquitoes, specifically in jungle or forest environments. It is characterized by fever, muscle pain, headache, nausea, vomiting, and in severe cases, jaundice, bleeding, and organ failure.

Use this code for confirmed cases of yellow fever acquired in sylvatic (jungle) cycles, typically involving non-human primates and forest-dwelling mosquitoes. Documentation should clearly indicate the patient's exposure history in endemic jungle areas and laboratory confirmation of yellow fever virus infection.

• Differentiate from urban yellow fever, which involves human-to-human transmission via Aedes aegypti mosquitoes.
• Ensure documentation specifies the sylvatic transmission cycle to support this specific code.
• Code any associated complications, such as hepatic failure or renal failure, separately.
