ABOUT DENGUE FEVER
|

DENGUE FEVER
CAUSE
Dengue fever can be caused by any one of four types of dengue virus: DEN-1, DEN-2, DEN-3, and DEN-4. You can be infected by at least two, if not all four types at different times during your lifetime, but only once by the same type.
TRANSMISSION
You can get dengue virus infections from the bite of an infected Aedes mosquito. Mosquitoes become infected when they bite infected humans, and later transmit infection to other people they bite. Two main species of mosquito, Aedes aegypti and Aedes albopictus, have been responsible for all cases of dengue transmitted in this country. Dengue is not contagious from person to person.
SYMPTOMS
Symptoms of typical uncomplicated (classic) dengue usually start with fever within 5 to 6 days after you have been bitten by an infected mosquito and include
· High fever, up to 105 degrees Fahrenheit
· Severe headache
· Retro-orbital (behind the eye) pain
· Severe joint and muscle pain
· Nausea and vomiting
· Rash
The rash may appear over most of your body 3 to 4 days after the fever begins. You may get a second rash later in the disease.
TREATMENT
There is no specific treatment for classic dengue fever, and like most people you will recover completely within 2 weeks. To help with recovery, health care experts recommend
· Getting plenty of bed rest
· Drinking lots of fluids
· Taking medicine to reduce fever
CDC advises people with dengue fever not to take aspirin. Acetaminophen or other over-the-counter pain-reducing medicines are safe for most people.
PREVENTION
The best way to prevent dengue fever is to take special precautions to avoid contact with mosquitoes. Several dengue vaccines are being developed, but none is likely to be licensed by the Food and Drug Administration in the next few years.
When outdoors in an area where dengue fever has been found
· Use mosquito repellents on skin and clothing.
· When outdoors during times that mosquitoes are biting, wear long-sleeved shirts and long pants.
· Avoid heavily populated residential areas.
· When indoors, stay in air-conditioned or screened areas. Use bednets if sleeping areas are not screened or air-conditioned.
· If you have symptoms of dengue, report your travel history to your doctor.
Because Aedes mosquitoes usually bite during the day, be sure to use precautions especially during early morning hours before daybreak and in the late afternoon before dark.
Other precautions include
· Keeping unscreened windows and doors closed
· Keeping window and door screens repaired
· Getting rid of areas where mosquitoes breed, such as standing water in flower pots, containers, birdbaths, discarded tires, etc.
