SARS-CoV-2 shows different clade and mutation patterns between community and clinical surveillance in Washington State, with Delta (21J) and BA.1 (21K) more common in community samples.
- Why it matters: Genomic surveillance often uses sequences from people seeking care, but it is unclear whether those genomes reflect community-circulating diversity, especially during pandemics.
- What they did: Using whole-genome sequences, the study compared community (Seattle area) versus Washington State Department of Health clinical samples, analyzing clade proportions, cluster diversity, non-synonymous mutations, and Ct values.
- The result: For RSV and influenza, clade proportions and sequence-cluster diversity were similar across settings, but SARS-CoV-2 clinical clusters were more diverse, Ct values were lower in clinical samples for multiple clades, and resistance-associated spike mutations were more prevalent in community samples.
