Dengue virus. Dengue virus ( DENV) is the cause of dengue fever. It is a mosquito -borne, single positive-stranded RNA virus of the family Flaviviridae; genus Flavivirus. [1] [2] Four serotypes of the virus have been found, and a reported fifth has yet to be confirmed, [3] [4] [5] all of which can cause the full spectrum of disease. [1]

Feb 5, 2010 · Dengue virus, which causes the infectious disease dengue fever, is an RNA virus that infects immune system cells. As shown in the animation, the virus binds to receptors on the host cell’s surface, which triggers the cell into taking in the virus. The host cell ends up translating the virus’s RNA into proteins that form a viral replication ...
