Warmer conditions are helping the Aedes albopictus mosquito, which transmits dengue, chikungunya and Zika viruses thrive, said the EU health agency.


  • Climate change is expected to significantly impact the spread of dengue in Europe.
  • Rising temperatures and increased rainfall create more favourable conditions for the spread of the disease, particularly in areas where the Aedes albopictus mosquito is present.
  • In southern Europe, particularly in Spain, Italy, and France, the risk of dengue is expected to increase due to the presence of Aedes albopictus and the rising temperatures and humidity.
  • However, in some countries like Spain and Portugal, the expected rise in summer droughts may decrease habitat suitability for Aedes albopictus.

Aedes albopictus mosquito:

  • The Aedes albopictus mosquito, commonly known as the Asian tiger mosquito, is a highly invasive species known for its distinctive black and white striped appearance.
  • Disease Vector: This mosquito is a known vector for several diseases, including Dengue fever, Chikungunya, Zika virus , and Yellow fever.

Controlling the spread of Aedes albopictus involves eliminating standing water where they breed, using insect repellents, and implementing community-wide mosquito control programs.
