Tropical and temperate regions, particularly '''Africa''' where it is thought to be present throughout the continent. Seroconversion in Kenya may be as high as 95% in animals of breeding age. In areas where infection prevalence is extremely high, no pathologic effects are seen due to the development of long lasting immunity at an early age.

Akabane virus is transmitted by '''insect vectors, mainly [[Ceratopogonidae|''Culicoides'' midges]]''' but also '''[[Culicidae|mosquitoes]]''' of the ''Aedes ''spp. and ''Culex'' spp. and some species of '''[[Ticks|tick]]'''. Mosquitoes appear to be solely mechanical vectors as no viral replication occurs within them.
