This is a serious viral disease transmitted by [[Ceratopogonidae|midges]] causing systemic signs and often death in the horse. It is a worldwide disease but is currently not found in the UK and is notifiable here. However, with global warming, the midge breeding area is growing and there are worries that in the future the disease will occur here. It affects horses, donkeys and mules and also is present subclinically in zebras and african donkeys. These can be a reservoir of infection for the disease. The disease has only been found in Africa, but since 1987 has recurred in Spain and Portugal.
