초록

목적: Coronavirus disease 2019 (COVID-19) 발생 이후 인간 코로나바이러스를 포함한 호흡기 바이러스의 패턴에 변화가 있을 것으로 생각되어, COVID-19 발생 이전 경기도 명지병원에 급성 호흡기 감염증으로 입원한 소아청소년을 대상으로 바이러스 감염의 패턴을 보고하였다. 방법: 2017년 1월부터 2019년 12월까지 급성 호흡기 감염증으로 명지병원에 입원한 18세 이하 소아청소년을 대상으로 하였고 real-time reverse transcription polymerase chain reaction (RT-PCR) 결과를 바탕으로 후향적으로 의무기록을 고찰하였다. 결과: 총 3,557명 중에서 중복감염 포함하여 3,686건의 바이러스가 검출되었고 평균 양성률은 78.6%이었으며 여름에 비해 겨울에 PCR 양성률이 높았다. 파라인플루엔자바이러스, 메타뉴모바이러스, 보카바이러스는 4-6월에 주로 검출되고, 인간엔테로바이러스는 7-9월에, 호흡기세포융합바이러스와 인플루엔자바이러스는 겨울철에 주로 검출되었다. 진단별로 인두편도염에서는 아데노바이러스가 가장 많았고 폐렴에서는 호흡기세포융합바이러스가 가장 많이 검출되었다. 인간 코로나 바이러스는 겨울철에 주로 검출되었으며, 크루프 환자 중에서 3번째 높은 빈도로 나타났다. 결론: 본 연구결과가 이전에 보고되었던 소아청소년의 호흡기 바이러스 역학과 크게 다르지 않았다. 또한 COVID-19 발생 이후 호흡기 바이러스 패턴 비교 연구에 도움이 되고자 COVID-19 발생 이전 호흡기 바이러스 역학정보를 보고하는 바이다.

Purpose: A change is expected in the pattern of respiratory viruses including human coronavirus (HCoV) after the coronavirus disease 2019 (COVID-19) outbreak. Accordingly, identifying the distribution of respiratory viruses before the COVID-19 outbreak is necessary. Methods: We retrospectively analyzed the results of samples of nasal swabs collected from children under aged ≤18 years who were hospitalized at Myongji Hospital, Gyeonggi-do due to acute respiratory infections from 2017 to 2019. Viruses were detected by real-time reverse transcription polymerase chain reaction (RT-PCR). Results: Out of 3,557 total patients, 3,686 viruses were detected with RT-PCR including coinfections. Of the 3,557 patients, 2,797 (78.6%) were confirmed as PCR-positive. Adenovirus and human rhinovirus (hRV) were detected throughout the year, and human enterovirus was most detected during summer. Respiratory syncytial virus, influenza virus, and HCoV were prevalent in winter. In patients with croup, parainfluenza virus was most frequently detected, followed by hRV and HCoV. The PCR positive rate in summer and winter differed significantly. Conclusions: Respiratory virus patterns in northwestern Gyeonggi-do were not much different from previously reported data. The data reported herein regarding respiratory virus epidemiological information before the COVID-19 outbreak can be used for use in comparative studies of respiratory virus patterns after the COVID-19 outbreak.
