What is Dengue?

Dengue is a viral infection transmitted by the bite of the female Aedes mosquito which breeds in free-standing water. It could be in your home, in potted plant trays, or even in your fridge. It can also be transferred to the unborn baby in a pregnant woman who is infected with the disease.

Congenital dengue is an arboviral disease caused by four types of the dengue viruses (DENV 1-4). Congenital dengue can be dangerous if untreated. The disease can vary from mild to intense, and can take dangerous forms which include dengue shock syndrome and dengue hemorrhagic fever (DHF). DHF is also known as break bone fever.


People can get dengue four times in their life. The major symptoms include:

  • High Fever.
  • Headache.
  • Vomiting.
  • Joint pain.
  • Skin rashes.
  • Rare symptoms include bleeding, low blood platelet count, low blood pressure (BP), etc.


Dengue is caused by the viruses spread by mosquito Aedes that thrive in and near human lodgings. When a mosquito bites a person infected with the virus of dengue, the virus enters the mosquito. When the infected mosquito bites another person, the virus enters the bloodstream of that person.


The main risks factors are:

  • Living or traveling to areas where the disease is widespread.
  • Prior infection with dengue virus.


To prevent the dengue virus from circulating, these are certain things one should take care of:

  • Wear and protective clothes properly covering your body.
  • Use mosquito repellent creams and sprays.
  • Reduce the habitat of the mosquitos.
  • Stay in well-screened housing.
