Table 1.

Probable HSV2 transmission paths.

Disease transmission path	HSV2-IP path ranking (normalised path cost)^a	HSV2-IT path ranking (normalised path cost)^a
anc-chimp → P.boisei → H.erectus	1 (1.0)	3 (1.14)
anc-chimp → H.habilis → P.boisei → H.erectus	4 (1.43)	1 (1.00)
anc-chimp → H.habilis → H.erectus	2 (1.20)	2 (1.05)
anc-chimp → H.rudolfensis → H.erectus	3 (1.24)	4 (1.54)

^aThe most probable path has a cost of 1. The path costs are normalised to the shortest path. The optimal path is shown in bold.
