What are the symptoms of Mild Dengue?

Characterized by sudden onset of high fever, weakness and prostration, severe headaches, retro-orbital pain, joint and muscle pain (myalgia), nausea, vomiting, and rash. The fever rises rapidly to as high as 104 F, and may be accompanied by bradycardia. The petechiae rash appears 3-4 days after the onset of fever, and usually appears on the trunk first, before spreading peripherally. Symptoms usually persist for 7 days, hence one of the common names for the disease: seven-day fever. Symptoms of hemorrhagic dengue are initially indistinguishable from dengue fever, but progress to faintness, shock, and systemic bleeding (gastrointestinal hemorrhage, etc.). The mortality rate for hemorrhagic dengue is 5%. Dengue does not produce long-term complications. Dengue can be confused clinically with influenza, measles, malaria, Colorado tick fever, scarlet fever, typhus, yellow fever, and other hemorrhagic fevers.
