SH2D3A and influenza: Our previous study showed that in addition to the nsp1 and nucleocapsid (N) genes, the nsp8 gene of SARS-CoV-2 was also highly expressed in clinical specimens, as revealed by nanopore whole-genome sequencing with the nanopore protocol for PCR tiling of COVID-19 (version PTC_9096_v109_revH_06Feb2020) (see Fig. S1 in the supplemental material) (Global Initiative on Sharing All Influenza Data [GISAID] accession number EPI_ISL_450409) (20).
