Alternative names: Dengue-like sickness; Breakbone fever; O’nyong-nyong fever

 Definition: Dengue fever is a mosquito-borne virus disease.


  • Dengue fever is a disease caused by one of four viruses that are all related. It is carried via mosquito bites, the most common of which is the Aedes aegypti mosquito, which is widespread in tropical and subtropical areas. Parts of the following can be found here:
  • Archipelago of Indonesia in northeastern Australia
  • Latin America and the Caribbean
  • Asia-Pacific
  • Africa sub-Saharan
  • The Caribbean in some places (including Puerto Rico and US Virgin Islands)

Dengue fever is uncommon in Canada and the United States. Dengue fever is not to be confused with dengue hemorrhagic fever, which is a different disease caused by the same virus but with far more severe symptoms.


Dengue fever is characterized by a rapid high temperature that can reach 105°F (40.5°C) four to seven days after infection.

2 to 5 days after the fever begins, a flat, red rash may emerge over the majority of the body. Later in the disease, a second rash that looks like measles occurs. Infected patients may have increased skin sensitivity and discomfort.

Other signs and symptoms include:

  • Fatigue
  • Pain in the head (especially behind the eyes)
  • Aches in the joints (often severe)
  • Muscle pain (often severe)
  • Vomiting and nausea
  • Lymph nodes swollen
  • Cough
  • Throat irritation
  • Stuffiness in the nose
