Thanks for that.

Here's a current example :

Bluetongue disease is transmitted by the Culicoides imicola midge. It is passed from animal to midge, and from midge to animal, but is not transmitted from animal to animal.

The virus, which affects cattle, sheep, goats and deer, has long blighted Africa, but in recent years has begun to spread northwards into Europe.

Some scientists believe that climate change could be behind its spread, as warmer temperatures have seen the biting insects gradually move north.
