Are You At Risk of Dengue Fever? Learn How To Prevent It

Dengue Fever is a tropical viral disease caused by Dengue Virus, vector born in nature transmitted by Aedes Aegypti Mosquito (having characteristics zebra like black and white marking on body). The disease outspreads in the season of winter as the mosquito grow best at temperature between 250C to 350C affecting 400 million people yearly (CDC). The disease is more common in densely populated urban areas of Southeast Asia (Pakistan, India and China)

Currently there is no definite vaccine available at market against Dengue Fever (although there are 6 vaccines in the process of preparation) thus the only preventive way is to “Fight the Bite” by keeping the mosquito away or by limiting the number of mosquito by reducing their habitats

Aedes Aegypti mosquito, unlike female anopheles mosquito of Malaria is active more at daytime rather than night and bites more at dusk and dawn. Thus the following preventive measure should be taken more seriously at that specific time

  • Frequently changes the water in vases, bowels and tanks. Cover water containers, bamboo pole holders, cans and buckets as these all are potential sites for dengue mosquito breeding.
  • Stagnant water, if not possible to cover or dry, pour kerosene oil to make a thin layer over water prevent the mosquito breeding.
  • In swimming pools or larger water tanks which cannot be cover or put kerosene oil in, the vector control can be achieved using Guppy fish (a small mosquito eating fish). Just release some Guppy fishes into the tank and they will eat the dengue mosquito larva.

07. Isolate the Infected Person
