What Is Dengue Fever?

June 28, 2020

Dengue Fever is a viral disease transmitted to humans by the bite of infected mosquitoes. The mosquitoes that carry Dengue viruses are found abundantly in tropical cities, breed in and around homes, and preferentially bite humans.

The virus is characterized by sudden onset of high fever, severe headache, and joint and muscle pain. Many patients have nausea, vomiting, and a rash that appears three to five days after onset of fever and may spread from the torso to the arms, legs, and face.

Dengue Fever is a rapidly expanding disease in most tropical areas of the world. The incidence of severe disease has increased dramatically in Southeast Asia in the past 20 years.

Dengue Fever Facts

  • There’s no specific treatment for Dengue infection.
  • The mosquitoes that carry the Dengue viruses are “day biting.”
  • These mosquitoes tend to feed indoors, in shady areas, or when the sky is overcast.
  • Peak feeding times are in the morning for several hours after daybreak and in the late afternoon for several hours before dark.

Travel Prevention Tips

  • Remain in well-screened or air-conditioned areas when possible.
  • Wear clothing that adequately covers the arms and legs.
  • Apply DEET-containing insect repellent to both skin and clothing.
  • Avoid outdoor activities at dawn and dusk.

This list is not conclusive. Consult your travel physician for additional health information. At this time, there are no vaccines available for prevention of Dengue Fever.
