A3692 - Epidemioloy and Etiology of Croup in Korea: Long-Term Study from 2009 to 2017
Author Block: Y. Sun; pediatric, gachon university gil hospital, Incheon, Korea, Republic of.
Rationale: Croup is one of the common pediatric respiratory illnesses that result in frequent visit to emergency department and hospitalization and cause substantial health care burden. However, little is known about the epidemiology and etiology of the croup in the other parts of the world, except the United States. The objective of the study was to delineate the etiology and epidemiology of the croup in Korea through long - term study period from 2009 to 2017.Methods: We examined the patients under the age of 18, hospitalized with croup at Gachon University Gil Hospital from February 2009 to April 2017. Dermographic data such as age, sex, diagnosis, admission date and respiratory virus study result were reviewed for analysis.Results: Croup was diagnosed in 1050 (6.3%) out of 14366 cases of lower respiratory tract infections. Males (60.95%) were more common than females. The mean age was 21.0 ± 14.5 months. For age distribution, admission rate was highest in the second year of life, and decreased gradually. More than 94% were under 48 months. Parainfluenza virus type 1 (16.9%) was the most common virus, followed by RSV (11.3%), rhino virus (8.0%), and corona virus (7.8%). A downward trend in croup hospitalization was demonstrated during the study period. There were two peaks, in summer (July to August) and spring (April to May). Winter (december) had the lowest frequency.Conclusions: The study has shown different epidemiologic data such seasonality compared to the previous results in the United States. Epidemiologic data of the croup can be helpful for guiding medical treatment
