FIG 1 — Maximum likelihood tree of 930 GII.4 major capsids generated by RAxML (66). Nodes with bootstrap support of less than 70 were collapsed. Rooting was optimized by TempEst (67). Tip color indicates major capsid subtype with epidemics in red tones and GII.4 viruses that spread globally in blue tones. Two long branches are observed: one leading to Hong Kong 2019 detected on 18 March 2019 and one leading to Den Haag 2017 detected on 21 February 2017. The corresponding tips are indicated by an arrow.
