Dengue Fever

In News 
  • The state has reported 467 instances of dengue from January 1 to April 12 even earlier than the arrival of the monsoon.
Dengue
  • Dengue virus is transmitted through the bite of a female Aedes (Ae.) mosquito.
  • Aedes is a day time feeder and can fly up to a limited distance of 400 meters.
  • Although it usually results in mild illness, severe dengue infections can sometimes prove fatal
  • World Health Organization (WHO) estimates suggest an annual incidence of 100-400 million dengue infections every year, with its global incidence growing dramatically “in recent decades”.
Major reason 

  • Inadequate source reduction of mosquito breeding sites and adult control measures.
  • Measures to control in that area are ignored.
  • Unprecedented human population growth.
  • Unplanned and rapid urbanisation.
  • Inadequate waste management.
  • Increased distribution and densities of vector mosquitoes due to man-made, ecological and lifestyle changes.
