The geographical distribution of members of the Great Island (GI) subgroup in the Kemerovo serogroup of orbiviruses extends from the Arctic to the Sub-antarctic. To examine the gene pool size of this group, five topotypes whose origins ranged from Iceland in the northern hemisphere to Macquarie Isla...
