RESULTS
DISCUSSION
Here, we use RNA-seq to characterize the differential host responses to SARS-CoV-2 infection in 286 NP swab and 53 WB samples from 333 individuals. Both NP swabs and WB from patients with COVID-19 show distinct patterns of activation or inhibition relative to other infections (influenza, seasonal coronaviruses, and bacterial sepsis) and to each other. SARS-CoV-2 infection was found to activate IFN-mediated antiviral pathways and paradoxically inhibit multiple additional immune…
