Characteristics Associated with Olfactory and Taste Disorders in COVID-19.

ABSTRACT:

Introduction

Olfactory and taste disorders (OTDs) have been reported in COVID-19 caused by severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2), the mechanisms of which remain unclear. We conducted a detailed analysis of OTDs as part of 2 seroepidemiological investigations of COVID-19 outbreaks.

Methods

Two retrospective cohort studies were conducted in a high school and primary schools of Northern France following a COVID-19 epidemic in February-March 2020. Students, their relatives, and school staff were included. Anti-SARS-CoV-2 antibodies were identified using a flow-cytometry-based assay detecting anti-S IgG.

Results

Among 2,004 participants (median [IQR] age: 31 [11-43] years), 303 (15.2%) tested positive for SARS-CoV-2 antibodies. OTDs were present in 9
