Dengue Fever,Facts,Symptoms,Prevention & Treatment



Dengue is a viral transmitted disease caused by any one of four closely related dengue viruses. This fever is transmitted by the bite of an Aedes mosquito infected with a dengue virus. The mosquito becomes infected when it bites a person with dengue virus in their blood. It can’t be spread directly from one person to another person.


  • Unlike malaria mosquitoes, this mosquitos bite during the day with their activity peaking at dawn and dusk So It is preferable to have all day protection.
  • Aedesaegypti lays eggs on the sides of containers and these remain stuck to the surface like glue. The eggs can survive without water for almost a year and hatch as soon as they are submerged in water.
  • The female dengue mosquito can lay eggs in any container which can hold some water. It can also lay eggs in the toilet tanks.
  • This mosquito prefers to rest indoors as this protects them from climatic changes thereby increasing their life span.
  • Total number of Cases per Year is 390 million.
