Dengue fever is a mosquito-borne viral illness caused by the dengue virus. It is characterized by sudden onset of fever, severe headaches, joint and muscle pain, rash, and fatigue. In severe cases, it can lead to dengue hemorrhagic fever or dengue shock syndrome, which can be fatal.
Dengue is prevalent in tropical and subtropical regions worldwide, where the Aedes mosquitoes thrive.
Prevention involves mosquito control measures and avoiding mosquito bites. There is no specific treatment, but supportive care can help manage symptoms.
