Oct. 9, 2019

Delhi Chief Minister Arvind Kejriwal tweeted the “stunning results” of his government’s campaign to get people to invest 10 minutes every week to stop dengue mosquitoes from breeding: “The number of cases in Delhi so far is just 356, compared to 650 by this time last year”, he posted.

About: 

  • Dengue is a mosquito-borne viral infection.

  • The dengue virus (DEN) comprises four distinct serotypes (DEN-1, DEN-2, DEN-3 and DEN-4) which belong to the genus Flavivirus, family Flaviviridae.

  • The Aedes aegypti mosquito is the main vector that transmits the viruses that cause dengue. 

  • It is found in tropical and sub-tropical climates worldwide, mostly in urban and semi-urban areas.

  • Once infected, humans become the main carriers and multipliers of the virus, serving as a source of the virus for uninfected mosquitoes. The infection causes flu-like illness, and occasionally develops into lethal complication called severe dengue.

  • Dengue is a notifiable disease, but a case is required to be notified only when the confirmatory test has been done in the lab.
