tMRCA estimated for each virus introduction in Africa. Coloured bars represent the mean tMRCAs (Supplementary Table 2, Global dataset) of each virus introduction in West Africa (blue), Egypt (orange), East-Central Africa (violet) and South Africa (yellow). Circles represent the area of origin of each virus introduction, based on the estimates summarised in the maximum clade credibility trees of each HPAI H5 clade.
