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