Limited within-host diversity and tight transmission bottlenecks limit SARS-CoV-2 evolution in acutely infected individuals
The recent emergence of divergent SARS-CoV-2 lineages has raised concerns about the role of selection within individual hosts in propagating novel variants. Of particular concern are variants...

New preprint 📢 We deep seq’d #SARSCoV2 and found within-host diversity is limited and rarely transmitted & transmission bottlenecks are narrow → slows the pace of #VOC emergence in *acute* infxs. We need to 👀 carefully at long-term infxs. 🧵 1/12 ⬇️
