Prevent Transmission of Dengue
How to Prevent Transmission?
Dengue is spread through the bite of an infected Aedes aegypti mosquito. The mosquito gets the virus by bitting an infected person. There is no way to tell if a mosquito is carrying the dengue virus. Therefore, people must protect themselves from all mosquito bites. All control efforts should be directed against the mosquitoes. It is important to take control measures to eliminate the mosquitoes and their breeding places. Efforts should be intensified before the transmission season (during & after the rainy season) and during epidemics.

Prevent mosquito bites
  1. Dengue Mosquitoes Bite during the daytime – protect yourself from the bite.
  2. Wear full sleeve cloths and long dresses to cover the limbs.
  3. Use repellents – care should be taken in using repellents on young children and elders.
  4. Use mosquito coils and electric vapour mats during the daytime to prevent dengue.
  5. Use mosquito nets to protect babies. old people and others who may rest during the day. The effectiveness of such nets can be improved by treating them with permethrine (Pyrethroid insecticide). Curtains (Cloth or Bamboo) can also be treated with insecticide and hung at windows or doorways, to repel or kill mosquitoes.
  6. Break the cycle of mosquito – human – mosquito infection. Mosquitoes become infected when they bite people who are sick with dengue. Mosquito nets and coils will effectively prevent more mosquitoes from bitting sick people and help stop the spread of dengue.
  7. To tighten all water containers regularly.
  8. Prevention of Aedes Aegypti mosquitoes breeding by emptying of household water containers at least once in a week.
Prevent the multiplication of mosquitoes
Mosquitoes which spread dengue live and breed in stagnant water in and around house.
  1. Drain out th water from desert / window air coolers (when not in use), tanks, barrels, drums, buckets etc.
  2. Remove all objects containing water (e.g. plant saucers, etc.) from the house.
  3. All stored water containers should be kept covered all times.
  4. Collect and destroy discarded containers in which water collect, e.g. bottles, plastic bags, tins, tyres etc.
