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.
