Dengue: Causes, Symptoms and prevention

Dengue is the infectious disease that is caused by dengue virus. This virus is transmitted by the bite from the Aedes aegypti female mosquito. It usually bites during a daytime, i.e., after sunrise and before sunset. This mosquito can bite at any place whether inside or outside of the home.
It is estimated that around 50-100 million people get infected by Dengue virus per year worldwide.
These mosquitoes generally breed in water containers and rarely fly more than 200 meters from the breeding site. It has been researched that these mosquitos do not breed in creeks, swamps, pools or other bodies of water.

  • The increase in the urban population that led to more sites for mosquitoes to develop.
  • International travelers who are travelling from the areas where dengue already spread to the areas that are not infected by dengue virus.
  • Environmental Changes that led Aedes mosquitoes to survive in the winter months.
How Dengue spread?
Dengue does not spread either of human interaction or mosquito bite alone, but it spread with the help of both the mosquito and the human. Initially, female Aedes bites an individual who has been infected with a dengue virus, the mosquito thus become a carrier of the virus. If the same mosquito bites some other individual, those individuals also get infected with the dengue virus.
