Abstract

Objectives: This study aimed to assess whether the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) Epsilon variant (B.1.429/427) is more virulent, leading to more hospitalization and more severe disease requiring intensive care unit (ICU) admission. Methods: SARS-CoV-2 genomic surveillance was performed on respiratory samples from 231 unique patients, collected at a single large health system in Southern California between November 2020 and March 2021 during the winter surge. Results: The frequencies of the Epsilon variant among outpatients, hospitalized patients, and ICU patients were indifferent. Conclusions: Our study suggests that the Epsilon variant is not associated with increased hospitalization and ICU admission.
