Dengue Symptoms , treatment

 dengue symptomsCauses

Dengue fever is caused by one of four different but related viruses. It is spread by the bite of mosquitoes, most commonly the mosquito Aedes aegypti , which is found in tropic and subtropic regions. This includes parts of:

  • Indonesian archipelago into northeastern Australia
  • South and Central America
  • Southeast Asia
  • Sub-Saharan Africa

Dengue fever is being seen more in world travelers.

Dengue fever should not be confused with Dengue hemorrhagic fever, which is a separate disease that is caused by the same type of virus but has much more severe symptoms.

Dengue fever begins with a sudden high fever, often as high as 104 – 105 degrees Fahrenheit.

A flat, red rash may appear over most of the body 2 – 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:

  • Headache (especially behind the eyes)
  • Fatigue
  • Joint aches
  • Muscle aches
  • Nausea
  • Swollen lymph nodes
  • Vomiting

Tests that may be done to diagnose this condition include:

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

There is no specific treatment for dengue fever. You will need fluids if there are signs of dehydration. Acetaminophen (Tylenol) is used to treat a high fever. Avoid taking aspirin.
