BTV is a notifiable disease because of the considerable economic losses it causes. Recent outbreaks in Northern Europe have been attributed to climate change creating favourable conditions for the BTV virus vector, Culicoides midges. The range of the midges have extended northwards and environmental conditions allow for extended breeding seasons.

Combined control

Once BTV is established in a country, it can be difficult to control and may be impossible to eradicate. The wide host range and the possible existence of latently infected carrier animals make elimination of the source of infection difficult.

Vector control and vaccination is necessary for successful BTV control.
