Dengue Fever

Dengue fever facts

  • Dengue fever is a disease caused by a family of viruses that are transmitted by mosquitoes.
  • Symptoms of dengue fever include severe joint and muscle pain, swollen lymph nodes, headache, fever, exhaustion, and rash. The presence of fever, rash, and headache (the "dengue triad") is characteristic of dengue fever.
  • Dengue is prevalent throughout the tropics and subtropics.
  • Dengue fever is caused by a virus, and there is no specific medicine or antibiotic to treat it. For typical dengue fever, the treatment is directed toward relief of the symptoms (symptomatic treatment).
  • The acute phase of the illness with fever and muscle pain lasts about one to two weeks.
  • Dengue hemorrhagic fever (DHF) is a specific syndrome that tends to affect children under 10 years of age. This complication of dengue causes abdominal pain, hemorrhage (bleeding), and circulatory collapse (shock).
  • The prevention of dengue fever requires control or eradication of the mosquitoes carrying the virus that causes dengue.
  • A vaccine for dengue fever was approved in April 2016 for use in dengue-endemic areas. Continue Reading
