Tissue tropism of SARS-CoV-2 in post-mortem samples
Fresh tissues were collected from a subset of post-mortem examinations and viral load quantified by use of qRT-PCR targeting the viral E gene (A). Detection of viral RNA was verified by use of qRT-PCR against the viral polymerase gene (data not shown). Tissues were additionally tested for subgenomic viral RNA transcripts (B). Dotted lines indicate the limit of detection as ascertained by negative control. Data are included for a 61-year-old man (PM1), a 64-year-old man (PM2), a 69-year-old woman (PM3), a 78-year-old man (PM4), and a 22-year-old man (PM5). qRT-PCR=quantitative RT-PCR. SARS-CoV-2=severe acute respiratory syndrome coronavirus 2.
