Bluetongue (BT)

Bluetongue (BT) is a viral disease which is transmitted from an infected animal to another animal through the bite of a midge. It can not be transmitted to humans. It mainly affects sheep, but can also manifest in cattle, goats and wild ruminants. From 2006 to 2010, this disease had major repercussions in Western Europe, causing significant economic losses for farmers. See our article on Bluetongue and on ANSES's role.
