Isolated rhinorrhea in the presentation of SARS-CoV-2 infection among preschool- versus school-aged children.

Objectives: Rapid identification and isolation of SARS-CoV-2 cases are priorities in school and child care settings to prevent further outbreaks. The objective of this study was to compare the clinical presentation of SARS-CoV-2 infections among preschool (<5 years) versus school-aged (≥5 years) children diagnosed with SARS-CoV-2 infection, and, specifically, the probability of presenting with an isolated symptom, such rhinorrhea or sore throat.

Methods: Retrospective study of children (≤18 years of age) diagnosed with SARS-CoV-2 in the outpatient COVID-19 clinic or the Emergency Department at the Centre Hospitalier Universitaire Sainte-Justine (Montreal, Quebec, Canada) February through May 2020.
