Spurred on by climate change, international travel and international trade, disease-bearing insects are spreading to ever-wider parts of the world.

This means that more humans are exposed to viral infections such as Dengue fever, Chikungunya, Zika, West Nile fever, Yellow fever and Tick-borne encephalitis.

For many of these diseases, there are as yet no specific antiviral agents or vaccines.

Global warming has allowed mosquitoes, ticks and other disease-bearing insects to proliferate, adapt to different seasons, migrate and spread to new niche areas that have become warmer.

These are the findings of a JRC report that aims to raise awareness about the threat posed by the spread of arboviruses (arthropod-borne viruses).

Aedes mosquitoes spread several arboviruses, including Dengue, Chikungunya, Zika, West Nile and Yellow fever viruses.

These mosquitoes thrive in urban settings due to the lack of natural predators and the ready availability of food and habitats in which to procreate.

They have existed in Africa and Asia for many years and are now becoming more and more widespread.
