Dengue fever is a mosquito-borne tropical viral disease transmitted by Aedes mosquitoes. Symptoms usually appear within 3–15 days of infection and include high fever, severe headache, vomiting, muscle pain, and joint pain. Most patients recover within 2–7 days, but in some cases, the illness can progress to severe forms such as Dengue Hemorrhagic Fever or Dengue Shock Syndrome, which may lead to bleeding, low platelet count, and dangerously low blood pressure.
