DENGUE FEVER

A Glimpse of the Silent Predator

With more than one-third of the world’s population living in areas at risk for transmission, dengue infection is a leading cause of illness and death in the tropics and subtropics. As many as 100 million people are infected yearly. Dengue is caused by any one of four related viruses transmitted by mosquitoes. There are not yet any vaccines to prevent infection with dengue virus (DENV) and the most effective protective measures are those that avoid mosquito bites. When infected, early recognition and prompt supportive treatment can substantially lower the risk of developing severe disease.


What is Dengue?

Dengue (pronounced den’ gee) is a disease caused by any one of four closely related dengue viruses (DENV 1, DENV 2, DENV 3, or DENV 4).The viruses are transmitted to humans by the bite of an infected mosquito.



Dengue fever and dengue hemorrhagic fever (DHF) are acute febrile diseases which occur in the tropics, can be life-threatening, and are caused by four closely related virus serotypes of the genus Flavivirus, family Flaviviridae. It is also known as breakbone fever. It occurs widely in the tropics.Each serotype is sufficiently different that there is no cross-protection and epidemics caused by multiple serotypes (hyperendemicity) can occur. Dengue is transmitted to humans by the Aedes aegypti or more rarely the Aedes albopictus mosquito, both of which feed exclusively during daylight hours.

DENGUE FEVER SYMPTOMS

How to know when it strikes…


The primary SYMPTOMS of dengue are:

  • High fever and at least two of the following:
  • Joint pain
  • Severe headache
  • Severe eye pain
  • Rash
  • Low white cell count or low blood platelet count
  • Muscle and bone pain
  • Mild bleeding manifestation (e.g., nose or gum bleed, petechiae, or easy bruising) Petechiae is a tiny purplish red spot on the skin caused by the release into the skin of a very small quantity of blood from a capillary.

Watch for warning signs as temperature declines 3 to 7 days after symptoms began.


IMMEDIATELY go to an emergency room or the nearby health care provider if any of the following warning signs appear:

  • Drowsiness or irritability
  • Severe abdominal pain or persistent vomiting
  • Bleeding from nose or gums
  • Red spots or patches on the skin
  • Black, tarry stools (feces, excrement)
  • Vomiting blood
  • Difficulty breathing
  • Pale, cold, or clammy skin



DIAGNOSIS: Signs And Tests

Tests that may be done to identify this condition include:

  • Complete blood count (CBC)
  • Serology studies to look for antibodies to dengue viruses
  • Antibody titer for dengue virus types
