In September bluetongue was detected in British livestock but what is blue tongue?
“Bluetongue is a disease of animals affecting all ruminants, including sheep, cattle, deer, goats and camelids (camels, llamas, alpacas, guanaco and vicuña). It does not affect horses. Although sheep are most severely affected, cattle are the main mammalian reservoir of the virus…… Bluetongue does not affect humans.” Defra.
How are these animals infected?
Bluetongue is caused by a virus which is carried by midges. The midges transmit the virus from one animal to another.
