Early detection and timely treatment is key in Dengue.

What is a Dengue virus?

  • Dengue spreads through Aedes aegypti mosquito which is infected with the virus. It bites during the daytime, mainly between dawn & dusk.
  • There exist 4 different strains of dengue virus known as DEN1, DEN2, DEN3 & DEN4. They all have potential to result in either dengue or a further serious kind of disease known as dengue hemorrhagic fever.
  • Rising population & a rise in global travel have caused transmission of this virus amongst different populations.
  • Dengue virus transmission has a cycle. A mosquito bites an infected human, it then bites another human & this cycle continues. Animals from jungles of Africa & Southeast Asia may also become bitten & infected with this virus and contribute to a widespread disease.

Risk Factors for Dengue:

Factors which increase our risk of being bitten by the dengue-causing mosquito are:

  • The journey during the rainy season
  • Living in cities in high-risk countries, mainly slum areas with no or less public health measures

The risk of contracting the dengue hemorrhagic fever is high if we have been infected earlier with a dengue virus.
