Similarity matrix of all pairs with available sequences. Gray: No Single Nucleotide Polymorphism Differences between pairs.*Pairs with SNP ≥2. Pair 11R-13I represents one patient. Positive after exposure to Index 11 but was briefly housed in a semi-private room prior to Index 11’s detection. Patient was relabeled as Index 13 with roommate exposure. Abbreviations: HCW, healthcare worker; I, index; P, patient; R, roommates; SNP, single nucleotide polymorphism. Color figures available online.
