Bluetongue is a viral disease primarily of sheep, but cattle, goats, camelids, wild or zoo ruminants, farmed cervids, and some carnivores are occasionally affected. The virus is transmitted by midges in the genus Culicoides. The virus is endemic in a broad, worldwide band of tropical and subtropical regions; however, outbreaks also occur outside this area, and the virus may persist long-term if the climate and vectors are suitable.
The Rocky Mountain Regional Animal Health Lab (RMRAHL) is the state laboratory with the Colorado Department of Agriculture. RMRAHL offers both ELISA and AGID testing for Bluetongue. Visit the CDAAHL website to learn more.
