Colorized scanning electron micrograph of a VERO E6 cell (blue) heavily infected with SARS-COV-2 ... [+] virus particles (orange), isolated from a patient sample. The Pittsburgh patient endured severe Covid-19 for about two and a half months before succumbing to the disease. Additionally, the vast majority were clustered in the N-terminal domain: Δ69-70, Δ141-144, Δ144-145, Δ146, Δ210, and Δ243-244 (Figures 2, 3, 4).
