ABSTRACT

Challenges in Inferring Intrinsic Severity of SARS-CoV-2 Omicron Variant from Early Population-Level Impact   [open pdf - 0B]

From the Abstract: "Inferring the severity of an emerging infectious agent presents specific challenges due to the inevitably imperfect state of data early in an epidemic. Here we specifically consider the additional impact of existing population immunity on estimates of intrinsic virulence, using the example of early evidence of the Omicron variant of SARS-CoV-2 [severe acute respiratory syndrome coronavirus 2] emerging in South Africa. Without accounting for vaccination rates and prior infections, among other factors, the true risk of severe infection will be systematically underestimated. At the time of writing it is premature to consider Omicron infections to be intrinsically milder that those caused by preceding variants."
