Abstract | Bluetongue is an infectious disease of ruminants. The etiological agent is Bluetongue virus that has double stranded RNA genome. Culicoides biting midges perform as a vector for virus spread. There are twenty seven bluetongue virus serotypes present in world. Bluetongue disease mainly affects sheep, goat, cattle, and camelids species. Bluetongue is a viral, non-contagious and infectious disease caused by a virus of the genus Orbivirus, transmitted by a hematophagous vector of genus Culicoides, to wild and domestic ruminants, primarily to sheep which is the most susceptible species. It is caused by link of endemic with climate conditions, with humidity and high temperatures. Economic loss is directly associated to abortion, loss of milk, death and meat production, weight loss and indirectly by restriction on export of the animals and their by-products. This article describes brief overview of bluetongue virus followed by its pathogenic potential and then its vector distribution and global epidemiology of its different serotypes.
