Updated data on geographical distribution of diseases are fundamental to take any decision about control strategies. This is particularly true for vector-borne diseases like bluetongue for which individual national efforts are not sufficient for assuring the effective surveillance and control of the infection and, therefore, an integrated multi-national approach is required to analyze both regional and global distribution of the infection as well as of the competent Culicoides vectors.

Information on genomic sequences of the virus are also useful for a better comprehensions of the relationships among the viral sub-populations in the different regions of the World.
