초록

목적: 코로나바이러스감염증-19 (coronavirus disease 2019, 코로나19) 대유행이 시작된 이후 새로운 변이 바이러스들이 지속적 출현으로 반복되는 코로나19 유행이 장기간 지속되고 있다. 본 연구는 국내 코로나19 유행 제3기와 제4기 중반까지 소아 청소년 환자의 임상적, 역학적 특성을 파악하고자 하였다. 방법: 코로나19 확진으로 입원한 18세 이하 환자의 의무기록을 후향적으로 분석하였다. 연구기간은 제3기 유행(2020년 11월 13일-2021년 7월 6일)과 제4기 유행(2021년 7월 7일-10월 31일)로 구분하였다. 결과: 총 93명이 분석에 포함되었다(제3기 33명, 제4기 60명). 제3기에 비해 제4기 환자군의 중간 연령이 유의하게 높았다(6.7세 vs. 2.8세, P=0.014). 가정 내 전파가 전체 환자의 60.2%에서 보고되었고 두 시기에서 유사하였다(69.7% vs. 55.0%, P=0.190). 전체 환자 중 87.1% (81명)가 유증상 확인자였다. 이중 12.3%는 호흡기 증상이 없었다. 후각/미각 소실은 제4기 유행 환자군에 더 많이 관찰되었다(10.7% vs. 34.0%, P=0.032). 대부분의 호흡기 감염은 상기도 감염(94.4%, 67/71)이었고 4명 환자에서 폐렴이 동반되었다. 두 유행기 동안 진단 시 바이러스 수치의 유의한 차이는 없었다. 결론: 단일기관 후향적 연구의 제한점이 있으나 국내 코로나19 유행 제3기와 제4기 중반 동안 소아청소년 환자는 대체로 경증이었고 두 시기에서 임상적 특성 차이가 관찰되었다.

Purpose: Since the coronavirus disease 2019 (COVID-19) pandemic began, new variants of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) have emerged, and distinct epidemic waves of COVID-19 have occurred for an extended period. This study aimed to analyze the clinical and epidemiological characteristics of children with COVID-19 from the third wave to the middle of the fourth epidemic wave in Korea. Methods: We retrospectively reviewed the medical records of hospitalized patients aged ≤18 years with laboratory-confirmed COVID-19. The study periods were divided into the third wave (from November 13, 2020 to July 6, 2021) and the fourth wave (from July 7 to October 31, 2021). Results: Ninety-three patients were included in the analysis (33 in the third and 60 in the fourth waves). Compared with the third wave, the median age of patients was significantly older during the fourth wave (6.7 vs. 2.8 years, P=0.014). Household contacts was reported in 60.2% of total patients, similar in both periods (69.7 vs. 55.0%, P=0.190). Eighty-one (87.1%) had symptomatic SARS-CoV-2 infection. Among these, 10 (12.3%) had no respiratory symptoms. Anosmia or ageusia were more commonly observed in the fourth epidemic wave (10.7 vs. 34.0%, P=0.032). Most respiratory illness were upper respiratory tract infections (94.4%, 67/71), 4 had pneumonia. The median cycle threshold values (detection threshold, 40) for RNA-dependent RNA polymerase (RdRp) and envelope (E) genes of SARS-CoV-2 were 21.3 and 19.3, respectively. There was no significant difference in viral load during 2 epidemic waves. Conclusions: There were different characteristics during the two epidemic waves of COVID-19.
