Table 3.

Degree of spatial admixture between rabies virus samples from Africa according to an Association Index (AI). AI values can range from 0 indicating complete population subdivision to 1 indicating complete panmixis.

Data	Spatial clustering level	No. of groups	AI [95% BCI]	P
N405	Sub-continent	3	0.04 [0.02−0.05]	<0.01
	Country	14	0.06 [0.05−0.08]	<0.01
N1350	Sub-continent	3	0.06 [0.04−0.08]	<0.01
	Country	10	0.13 [0.09−0.13]	<0.01

BCI, Bayesian confidence interval. Datasets of partial (N405) and full (N1350) nucleoprotein sequences were tested at two levels of spatial aggregation: (1) sub-continent geographical partitions relative to Tanzania (three states: Tanzania, neighbouring country, and other African country) and (2) country of origin.
