Prevention

The best way to prevent dengue virus infection is to take special precautions to avoid being bitten by 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 repellent 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 take 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.
