THE PREVENTION OF DENGUE FEVER
OVERVIEW
Dengue fever can be caused by any one of four types of dengue virus.
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 daysafter 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
Marked damage to blood and lymph vessels
Bleeding from the nose, gums, or under
the skin, causing purplish bruises
Fluids leaking outside of blood vessels
Massive bleeding
Shock (very low blood pressure)
DIAGNOSIS
Your health care provider can diagnose dengue fever by doing two blood tests, 2 to 3 weeks apart.
The tests can show whether a sample of your blood contains antibodies to the virus. In epidemics, a health care provider often can diagnose dengue
by typical signs and symptoms.
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 a mosquito repellant containing
DEET, picaridin, or oil of lemon eucalyptus
Dress in protective
clothing-long-sleeved shirts, long pants, socks, and shoes
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.
COMPLICATIONS
Most people who develop dengue fever recover completely within 2 weeks. Some, however, may go through several weeks to months of feeling tired and/or depressed.
