SARS-CoV-2 Omicron variant found to display increased resilience to antiviral type I interferon response

In a new study, scientists have compared the Omicron variant with the Delta VOC (B.1.617.2) as well as the wildtype strain (B.1), with respect to their interaction with the antiviral type 1 interferon response in infected cells.

Cannabidiol inhibits SARS-CoV-2 replication in human cells and mice

In research recently published in the journal of Science Advances, an interdisciplinary team of researchers from the University of Chicago assessed the potential role of cannabidiol (CBD), a natural product extracted from the cannabis plant, to prevent and inhibit severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infections in human cells and mice.

SARS-CoV-2 infection found in wild white-tailed deer in Canada

In a recent study posted to the bioRxiv* preprint server, scientists investigated severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection in white-tailed deer (WTD) in southern Québec, Canada, as part of a more extensive pan-Canadian analysis into SARS-CoV-2 spillover into wildlife. To further define SARS-CoV-2 infection in this species, researchers used viral genomes and isolation.
