Dengue fever is a prevalent mosquito-borne illness caused by dengue virus and transmitted by Aedes aegypti mosquitoes. It affects over 100 countries and causes 50-100 million infections annually. The disease presentation varies from a nonspecific viral syndrome to severe dengue hemorrhagic fever/dengue shock syndrome. There is no vaccine currently available and treatment involves supportive care, with careful fluid management needed for severe cases to prevent shock. Prevention relies on personal protection from mosquito bites and reducing mosquito breeding sites.
