Dengue (dengue fever) is a viral infection. It is a viral hemorrhagic fever caused by a member of the Togaviridae family of RNA viruses. The disease is spread by mosquitoes [mosquito-borne disease] such as Aedes aegypti and Aedes aegyptilalbopictus. The infection is endemic in certain parts of the world. Accordoing to the World Heath Organization 50 million new cases occur annually and 2,500 million individuals are at risk. Dengue fever is associated with fever, shock and sometimes death.
