What is a vector-borne disease?

A vector borne disease is one that is transmitted to humans via insects.

For example, dengue or malaria are borne by mosquitoes, which get infected by biting humans who carry the virus and, in turn transmit the disease to healthy humans by biting them. Mosquitoes know no borders and typically thrive in a warm, humid environment, which means climate change may help them spread to new countries.
