Dengue is a mosquito-borne acute systemic viral infection caused by any of the four serotypes of the dengue virus.

Clinical presentation

The infection can lead to a broad spectrum of symptoms ranging from mild, nonspecific, influenza-like prodromes called dengue fever to more severe forms known as:

  • dengue hemorrhagic fever
  • dengue shock syndrome 



The dengue viruses (DENV) are single-stranded RNA arboviruses that are divided into four different serotypes, nominated DENV-1, -2, -3, and -4. They belong to the family Flaviviridae and the genus Flavivirus.
