Graphics depicting proposal steps H-J for new transmission trees, keeping the phylogenetic tree unchanged. In all panels, the initial situation is at the top, and the proposal below. Every panel shows part of an outbreak, with red arrows indicating transmission to depicted or undepicted hosts. Only in panel B host I must be the index case. The purple host is the focal host, with the dark purple arrow indicating the proposal for the new infection time Ii’; the light purple arrow in panels B and C indicate the proposal for the new infection time Ij’ of the focal host’s infector. The grey parts of the phylogenetic tree are moved between the hosts. (H) the focal host is not the index case, and Ii’ is after MRCAI,II of the focal host and his infector; (I) the focal host is not the index case, and Ii’ is before MRCAI,II of the focal host and his infector (the index case), and Ij’ is after MRCAI,II; (J) the focal host is not the index case, and Ii’ is before MRCAII,III of the focal host and his infector, but after the MRCAI,III of the focal host and his infector’s infector; also, Ij’ is after MRCAII,III.
