Clinical Information
  • Acute infectious, eruptive, febrile disease caused by four antigenically related but distinct serotypes of the dengue virus; transmitted by the bite of infected aedes mosquitoes, especially a. Aegypti; classical dengue (dengue fever) is self-limiting and characterized by fever, myalgia, headache, and rash; dengue hemorrhagic fever is a more virulent form of dengue virus infection.
  • An acute febrile disease transmitted by the bite of aedes mosquitoes infected with dengue virus. It is self-limiting and characterized by fever, myalgia, headache, and rash. Dengue hemorrhagic fever is a more virulent form of dengue.
  • An acute infection caused by dengue virus. Signs and symptoms include sudden onset of fever, headache, rash, arthralgia, and myalgia. It is transmitted through mosquitoes.
  • An acute, infectious tropical disease caused by an arbovirus transmitted by mosquitoes
  • Dengue is an infectious disease caused by a virus. You can get it if an infected mosquito bites you. It is common in warm, wet areas of the world. Outbreaks occur in the rainy season. Dengue is rare in the United States. Symptoms include a high fever, headaches, joint and muscle pain, vomiting and a rash. Most people with dengue recover within 2 weeks. Until then, drinking lots of fluids, resting and taking non-aspirin fever-reducing medicines might help. Sometimes dengue turns into dengue hemorrhagic fever, which causes bleeding from your nose, gums or under your skin. It can also become dengue shock syndrome, which causes massive bleeding and shock. These forms of dengue are life-threatening.to lower your risk when traveling in dengue-prone countries
