Answer

Dengue infection is caused by dengue virus (DENV), which is a single-stranded RNA virus (approximately 11 kilobases long) with an icosahedral nucleocapsid and covered by a lipid envelope. The virus is in the family Flaviviridae, genus Flavivirus, and the type-specific virus is yellow fever.
