چکیده
Akabane disease is a viral disease of ruminants that is mainly characterized by fetal damage. Inapparent infections in adults can lead months later to abortions, stillbirths and congenital defects in newborns. Most affected neonates die or must be euthanized. Before vaccines were developed, Akabane disease caused significant economic losses in some countries. Between 1972 and 1975, this virus resulted in the birth of more than 42,000 abnormal calves in Japan. A few strains of Akabane virus can also cause outbreaks of encephalomyelitis in calves and adult cattle. The latter syndrome has been considered rare, but in 2006, an outbreak affected nearly 200 cattle in Japan. There is no treatment for Akabane disease.
