Clustering of severe acute respiratory syndrome coronavirus 2 cases related to nightclub event, Amsterdam, the Netherlands, June 2021. Red circles indicate sequences linked to the nightclub. A) Maximum-likelihood tree of all sequences (n = 4,905) in the dataset. B) Magnification of the clade (highlighted in blue in panel A) containing sequences linked to the nightclub (n = 1,663). Branches without tips depict other Netherlands Delta variant sequences derived from GISAID (https://www.gisaid.org).
