Symptoms of Dengue Fever
Symptoms, which usually begin four to six days after infection and last for up to 10 days, may include
Sudden, high fever
Severe headaches
Pain behind the eyes
Severe joint and muscle pain
Fatigue
Nausea
Vomiting
Skin rash, which appears two to five days after the onset of fever
Mild bleeding (such a nose bleed, bleeding gums, or easy bruising)
Sometimes, symptoms are mild and can be mistaken for those of the flu or another viral infection. Younger children and people who have never had the infection before tend to have milder cases than older children and adults. However, serious problems can develop.
