Seasonal influenza in children at Gwangju during 2018-2019: A single institution analysis

Purpose: According to the WHO, about 290,000 to 650,000 people are killed each year by seasonal influenza virus, and the proportion of influenza-like illness (ILI) by age group for the 2015-2016 flu season in Korea accounts for 70% of all occurrences in the 0-18 year old age group. In this study, we compared the clinical features of influenza type A and B in children, and the difference between the oseltamivir and peramivir groups for further treatment. Methods: The medical records of 112 children with influenza-like symptoms from September 2018 to April 2019, and who underwent rapid influenza diagnostic test were retrospectively reviewed. Results: Influenza A positive patients showed the highest distribution in the 0-1 year old group, and influenza B positive patients had the highest distribution in the 7-18 year old group. Fever duration after administration of antiviral agents was longer in type B. Influenza type A and B were compared with hospitalization period and total fever duration, but there was no statistical significance. Conclusion: In this study, clinical symptoms and laboratory tests according to influenza A and B were not statistically significant. And there was no statistically significant difference between hospitalization and fever duration according to the type of antiviral agent. But, in type B, the age of patients was higher and the duration of fever after antiviral treatment was longer.
