(A) Maximum likelihood estimation for the mean transmission bottleneck size among paired-patients. Values represented as colored dots correspond to the hypothesized linked pairs, while the gray dots correspond to pairs that include at least one control patient. (B) Schematic representation of patients’ interaction across the epidemiological cluster. Arrows indicate the hypothesis of transmission direction. The subjects in the study are colored according to the SARS-CoV-2 lineages
