Less blooming strains, that are less adapted to humans, may become good starting strains for the next outbreak, resulting in a backset after one outbreak, as observed in Figs 5b and 6b and Supplementary Fig. 2. Hence, the evolutionary change focusing on strains belonging to a single outbreak looks higher than those belonging to multiple outbreaks, giving a steeper slope.
