Comparison of Clinical Manifestations of RSV, Rhinovirus and Bocavirus Infections in Children with Acute Wheezing

Abstract

Purpose :The purpose of this study was to compare clinical manifestations of human bocavirus (hBoV), respiratory syncytial virus (RSV), and human rhinovirus (hRV) in children with acute wheezing. Methods :We retrospectively investigated 549 virus-positive throat swabs obtained between January 2006 and December 2008 from pediatric inpatients with acute respiratory tract disease at Kwangju Christian Hospital. Among them, 109 patients, who had lower respiratory tract infections with wheezing, were enrolled in this study. The medical records of patients with positive results were reviewed for clinical data. Results :The mean age of the patients with RSV was 7.15 months, 15.66 months in those with hRV, and 15.04 months in those with hBoV. The mean fever duration and frequency of patients with fever was 2.43 days and 47.9% for RSV, 2.86 days and 51.7% for hRV, and 3.75 days and 69.6% for hBoV. The frequency of patients with acute otitis media was 20.8% in the RSV, 20.7% in the hRV, and 13.0% in the hBoV groups. The frequency of lung infiltration on chest X-ray was 12.5% in the RSV, 20.7% in the hRV, and 47.8% in the hBoV groups. Conclusion :We compared the clinical manifestations of respiratory viral infections in infants and children with wheezing. However, further surveillance will be necessary to clarify the clinical manifestations of the viruses. [Pediatr Allergy Respir Dis(Korea) 2011;21:334-343]
