Overview on dengue

Dengue is a mosquito-borne viral infection reported in various countries all over the globe. Generally, the infection is mild and settles in a week without triggering any lasting effects. In rare instances though, it can become serious and life-threatening.

Even today, there is no specific treatment or vaccine which is why it is vital to avoid being bit by mosquitoes when staying or visiting in areas where the disease has been reported.

Dengue is spread by infected mosquitoes, specifically the Aedes aegypti and albopictus strains. These mosquitoes bite during the day, usually early morning or in the early evening before dusk. The mosquitoes are often present around sources of stagnant water including in water storage tanks and wells.


The indications of dengue generally arise abruptly in 4-10 days after being infected such as:

  • Fever than can reach up to 40 degrees C or higher

Management of dengue
