SARS-CoV-2 variants and SNP distances involved in reinfections identified by 1-to-1 whole-genome sequencing comparison for patients in Madrid, Spain, March 2020–March 2021*
Patient | Specimen 1 | Specimen 2 | No. SNPs† |
---|---|---|---|
5 | B | B.1.177 | 22 |

*The 2 reinfections not confirmed (short tandem repeat host analysis revealed that the 2 sequential specimens belonged to different patients) are not included. SARS-CoV-2, severe acute respiratory syndrome coronavirus 2; SNP, single-nucleotide polymorphism. †Including insertions/deletions.
