Clin Exp Pediatr. 2023;66(3):134-141.   Published online December 22, 2022
Question: The clinical differences between severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) and human coronaviruses (HCoV) in children remain unknown.
Finding: This study compared the clinical findings of children infected with SARS-CoV-2 versus HCoV. Its findings suggest that children and adolescents with SARS-CoV-2 have a milder clinical course than those with HCoV.
Meaning: The clinical course of children and adolescents with SARS-CoV-2 should be closely monitored during the coronavirus disease 2019 pandemic.

Clin Exp Pediatr. 2022;65(12):563-573.   Published online October 17, 2022
The identification of the causative pathogens of community-acquired pneumonia and appropriate treatment and prevention can reduce mortality and the socioeconomic burden by reducing the medical expenses. The world has been in the coronavirus disease 2019 pandemic since 2020, and there is always a risk of continuous emergence and epidemic of new respiratory infectious diseases. Therefore, it is important to sustain a monitoring system for respiratory infectious diseases including pneumonia.

Clin Exp Pediatr. 2015;58(10):380-385.   Published online October 21, 2015
Purpose

Croup is a common pediatric respiratory illness with symptoms of varying severity. Moreover, epiglottitis is a rare disease that can rapidly progress to life-threatening airway obstruction. Although the clinical course and treatments differ between croup and epiglottitis, they are difficult to differentiate on presentation. We aimed to compare the clinical characteristics of croup and epiglottitis in Emergency Department patients.
