Up to one hundred times more super-spreaders with Omicron
“A much larger proportion of individuals infected with the new variants are high, very high or super-emitters of airborne viruses: for the original wild type, one in 1,000 infected was a super-emitter; for Delta one in 30; and for Omicron one in 20 or one in 10, depending on the viral load estimate used.
Testing of the effectiveness of protective strategies in view of the lower critical dose suggests that surgical masks are no longer sufficient in most public settings, while correctly fitted FFP2 respirators still provide sufficient protection, except in high aerosol producing situations such as singing or shouting.”
Research: Higher viral load and infectivity increase risk of aerosol transmission for Delta and Omicron variants of SARS-CoV-2
