What is a Dengue Virus test?

Dengue is a virus-caused disease that is spread by mosquitoes. It is a painful, debilitating mosquito-borne disease caused by any one of four closely related dengue viruses.

Most cases in the United States occur in people who contracted the infection while traveling abroad. But the risk is increasing for people living along the Texas-Mexico border and in other parts of the southern United States.

Who should get this test?

Dengue may usually occur to children and even adults. Dengue fever begins with a sudden high fever, often as high as 105°F (40.5°C), 4 to 7 days after the infection.

A flat, red rash may appear over most of the body 2 to 5 days after the fever starts. A second rash, which looks like the measles, appears later in the disease. Infected people may have increased skin sensitivity and are very uncomfortable.

Other symptoms include:

  • Fatigue
  • Headache (especially behind the eyes)
  • Joint aches (often severe)
  • Muscle aches (often severe)
  • Nausea and vomiting
  • Swollen lymph nodes
  • Cough
  • Sore throat
  • Nasal stuffiness
