Abstract

Purpose
: Although influenza is one of the most important causes of acute respiratory tract infections in children, effective antiviral therapies are not common and there are only a few clinical studies on treatment of influenza in children. We evaluated the efficacy of oseltamivir in the treatment of naturally aquired influenza in children during the first half of 2004 in Busan.
Methods
: From January 2004 to June 2004, throat swabs and nasal washes were performed and cultured for the isolation of influenza virus and tested by rapid antigen detection test(QuickVue influenza test) in children with suspected influenza infections. The children who responded positively to the QuickVue influenza test, we divided into two groups : an oseltamivir treatment group and a control group. We compared their clinical symptoms(including fever duration) and diagnosis. The medical records of patients with influenza virus infection were reviewed retrospectively.
Results
: A total of 621 individuals were suspected of influenza infection. Influenza viruses were isolated in 79(17.2 percent) out of 621 patients examined. QuickVue influenza tests were positive in 181 cases. The treatment group(83 individuals) received oseltamivir twice daily for 5 days, and the control group(99 individuals) were administered only symptom relief medicine. There was no differences between the two groups in clinical diagnosis and symptoms. Oseltamivir treatment reduced the fever duration and other respiratory symptoms. There were no adverse events associated with oseltamivir treatment.
Conclusion
: Our data suggest that oral oseltamivir treatment reduces the fever duration and other respiratory symptoms of acute influenza without side effects in children.
