황열병, or yellow fever, is a viral disease transmitted by the bite of infected mosquitoes, particularly the Aedes aegypti species. It is characterized by fever, chills, loss of appetite, and muscle pain. In severe cases, it can lead to liver damage, resulting in jaundice and bleeding. Vaccination is the most effective way to prevent 황열병. The yellow fever vaccine provides long-lasting immunity and is recommended for travelers to areas where the disease is endemic. Early diagnosis and supportive care are crucial for managing symptoms and reducing complications.
