Omicron appears more deadly than seasonal influenza, study suggests
Adults hospitalised with the SARS-CoV-2 Omicron variant have a higher death rate than those hospitalised with seasonal influenza, even though Omicron is considered less virulent with lower case fatality rates than the delta and alpha strains, new research being presented at ECCMID suggests.
