Symptoms of Dengue Fever

Dengue fever is transmitted by the bite of an Aedes mosquito infected with a dengue virus during day time. The mosquito becomes infected when it bites a person with dengue virus in their blood. Dengue is a disease that needs urgent medical intervention as it is characterized by severe symptoms. If medical assistance is delayed and not proper, the disease can compound and cause multi organ failure, also lead to death.

Symptoms of Dengue Fever

Common Symptoms of Dengue :

Initial Symtoms of Dengue are as :

  • 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. These include dengue hemorrhagic fever, a rare complication characterized by high fever, damage to lymph and blood vessels, bleeding from the nose and gums, enlargement of the liver, and failure of the circulatory system. The symptoms may progress to massive bleeding, shock, and death. This is called dengue shock syndrome (DSS).
