SARS-CoV-2 antigen levels associated with COVID-19 severity and other clinical outcomes

The amount of SARS-CoV-2 antigen measured in the blood of patients hospitalized with COVID-19 is associated with illness severity and other clinical outcomes, according to a new study published in the Annals of Internal Medicine.

29 Aug 2022

The clinical and virological outcomes associated with molnupiravir or nirmatrelvir–ritonavir use in hospitalized patients with mild-to-moderate COVID-19

Researchers investigated whether early treatment with oral antivirals prevented all-cause mortality in hospitalized patients infected with SARS-CoV-2 new variant of concern Omicron BA.2 subvariant.
