The best approach towards preventing the dengue fever is to take precautions in order to avoid being bitten by the aedes aeqypti mosquito. The necessary precautions to prevent infection are as follows:

  1. Protective clothing – You must wear long clothing when there is an outbreak of dengue or when you are travelling to an infected region. Full pants and long-sleeved shirts decrease the exposure of skin,  and lower the chances of a mosquito bite and subsequent transmission of the virus in your body. Furthermore, spray an insecticide containing permethrin on clothes to keep away the virus-carrying insect.
  2. Vector control – When you suspect the risk of dengue epidemic, implement community vector control programs to eliminate potential breeding grounds for the vector mosquitoes. Stagnant water around human habitation should be cleared (at least once in a week) and water in the vases/containers /barrels/drums must be changed regularly. Surface wells must be well-maintained or covered to make sure that mosquitoes do not breed in the vicinity. Rain water and surface water should also be cleared. Besides vector control,  spray a good-quality insecticide around the area where you spend most of your time.
  3. Using insect repellent – Use insect repellent containing N, N-iethyl-3-methylbenzamide (DEET) to reduce the risk of getting infected during a dengue threat. When there is a danger of dengue outbreak or there is dengue outbreak, use insect repellent containing N, N-diethyl-3-methylbenzamide (DEET) to reduce the risk of an infecting bite.  The mosquito repellent must be applied in the most exposed areas of skin such as back of the neck and wrists.
  4. Sleeping in a mosquito net – You should take extra precautions such as  sleeping in a mosquito net,  this will limit the risks of a bite at night.
  5. Stay indoors during the day – Aedes mosquitoes bite during the day, therefore, it is advisable to remain indoors as much as possible during the daytime.
  6. Precautions when travelling – If you are travelling to a place where dengue is endemic, try to stay  in a well-screened or air conditioned place.
