Abstract

Purpose: We evaluated the clinical features of croup in children according to viral etiology. Methods: This study enrolled pediatric patients with croup, who showed positive results on respiratory virus reverse transcriptase polymerase chain reaction performed between January 2012 and December 2017. We retrospectively reviewed the medical records. Results: A total of 179 patients (119 boys and 60 girls) were enrolled with the mean age of $18.9{\pm}14.7$ months. The viruses commonly identified were parainfluenza, respiratory syncytial virus, rhinovirus, and influenza. Among these 4 viruses, patients with rhinovirus infection showed significantly shorter fever and admission durations. Patients with parainfluenza infection showed significantly lower incidences of epinephrine nebulization and patients with influenza infections showed significantly higher incidences of steroid treatment. Conclusion: Clinical manifestations of croup differ according to causative viruses. Further studies should be conducted to evaluate the severity and prognosis of croup according to viral etiology.
