Fig. 1

Minimum spanning tree network of vir haplotypes. The size of each circle is proportional to the given haplotype frequencies. The country of origin of each haplotype is represented by a specific colour. Two P. vivax Sal-I and PO01 reference sequences are also included for vir 4 (AAKM01000104 and PVP01_0006010), vir 12 (AAKM01000016 and PVP01_1035200), vir 21 (AAKM01000003 and PVP01_1101100) and vir 27 (AAKM01000041 and PVP01_0949900)
