Fig. 4From: Systematic genomic analysis of SARS-CoV-2 co-infections throughout the pandemic and segregation of the strains involvedChronological within-host dynamics of co-infecting strains for the five patients with more than one specimen available from different periods. Pie charts depict the relative proportion of each co-infecting strain at each sampling time point. The colour of each pie sector corresponds to the lineages involved in each co-infection (see legend)Back to article page
