Sylvatic yellow fever

This code represents an acute viral hemorrhagic disease transmitted by mosquitoes, specifically in non-urban, jungle, or forest environments. It is characterized by fever, muscle pain, headache, nausea, vomiting, and in severe cases, jaundice and hemorrhage.

Apply this code when documentation clearly indicates a diagnosis of yellow fever acquired in a sylvatic (jungle/forest) cycle, involving non-human primates and forest-dwelling mosquitoes. Supporting documentation would include a confirmed diagnosis of yellow fever with epidemiological evidence pointing to a sylvatic transmission route.

• Differentiate from urban yellow fever, which involves human-to-human transmission via Aedes aegypti mosquitoes.
• Ensure documentation specifies the transmission cycle (sylvatic vs. urban) for accurate coding.
• Consider additional codes for specific manifestations or complications, such as jaundice or hemorrhage, if documented.
