Key Facts, Prevention & Control of Dengue

Key Facts

  • Dengue is a viral infection spread by mosquitoes causing a severe flu-like illness and, sometimes causing a potentially lethal complication called severe dengue haemorrhagic fever. Therefore, close monitoring of platelet count while undergoing treatment is important.
  • The Aedes aegypti mosquito is the main vector that transmits the viruses that cause dengue. The viruses are passed on to humans through the bites of an infective female Aedes mosquito, which mainly acquires the virus while feeding on the blood of an infected person.
  • Victims of dengue often have intense joint and muscle pain.
  • Complications arise due to depletion of cellular components in the blood which prevent normal clotting.

Look for these symptoms

  • High grade fever (104° F)
  • Body ache
  • Joint or bone pain
  • Severe headache
  • Eye pain,
  • Swollen lymph nodes
  • Rash and in some cases mild bleeding from gums or nose

Risk factors

  • Living or traveling in tropical areas
  • Prior infection with dengue fever virus.

    – Tightly cover water containers, wells and water storage tanks.
    – Prevent stagnation of water by topping up all defective ground surfaces, disposal of plastic containers, automobile tyres etc safely.
