Figure 2

Kriging map of the dates of exposure to Bluetongue virus serotype 8. The dates were expressed as a number of days since the first clinical case herd during the 2007 epizootic in France (31st July 2007), and location of reported case herds (black crosses). The hatched areas correspond to regions with no data (from [15]).
