Urban yellow fever

This code represents an acute viral hemorrhagic disease characterized by fever, muscle pain, headache, loss of appetite, nausea, and vomiting, specifically when contracted in an urban environment. In severe cases, it can lead to jaundice, bleeding, and organ failure. The disease is transmitted by infected mosquitoes, primarily Aedes aegypti.

This code is appropriate for confirmed cases of yellow fever where the infection was acquired in an urban setting. Documentation should clearly indicate a diagnosis of yellow fever and specify an urban exposure or transmission context. This would typically be supported by laboratory confirmation and epidemiological investigation.

• Differentiate from "Jungle yellow fever" (A95.0), which is transmitted in forest or jungle areas.
• Ensure documentation explicitly states "urban" or provides context indicating urban acquisition.
• Sequence as the primary diagnosis when yellow fever is the reason for the encounter.
