Abstract

Purpose: Infants aged ≤90 days with fever are susceptible to severe infections. This study aimed to analyze the clinical features of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection in this particular age group. Methods: Infants aged ≤90 days who were diagnosed with coronavirus disease 2019 (COVID-19) and hospitalized between March 1, 2020, and May 1, 2022 were included. Medical records of patients were retrospectively reviewed. Results: A total of 105 infants with COVID-19 were included; 27 (25.7%) neonates aged <28 days, and 48 (45.7%) and 30 (28.6%) infants aged 28-59 days and 60-90 days, respectively. Five (4.7%) patients remained asymptomatic and 68 (62.8%) were febrile, with a median fever duration of 2 days. The most common symptoms were respiratory including cough (66.6%), nasal stuffiness (51.4%), and rhinorrhea (40.9%). Blood cultures were performed in 10 infants but no organisms were detected. Cultures of bag-collected urine specimens from 8 infants were grown, resulting in positive growth for 2 without pyuria. Nine (8.6%) infants were treated with empirical antibiotics for a median duration of 2.3 days (range, 1-7 days). All 105 infants showed improvement without any complications, and there were no fatal cases. Conclusions: In this study, most infants aged ≤90 days with COVID-19 presented with mild symptoms and none of those evaluated had documented bacterial co-infection. The favorable prognosis among young infants with SARS-CoV-2 may aid clinicians in tailoring their approach to evaluation and management during outbreaks.

목적: 발열이 있는 생후 90일 이하의 영아에게는 심각한 감염의 위험이 높다. 본 연구는 코로나바이러스감염증-19 감염증(코로나19)이 발생한 90일 미만의 영아의 임상적 특징을 분석하기 위해 진행되었다. 방법: 2020년 3월 1일부터 2022년 5월 1일까지 코로나19로 진단받고 입원한 생후 90일 이하 영아의 의무기록을 후향적 연구로 검토하였다. 결과: 총 105명의 영아가 포함되었으며, 이 중 27명(25.7%)은 생후 28일 미만 신생아, 48명(45.7%) 및 30명(28.6%)는 각각 생후 28-59일과 60-90일 사이의 영아였다. 이 중 5명(4.7%)은 무증상이었고, 68명(62.8%)은 발열이 있었으며, 평균 발열 기간은 2일이었다. 가장 흔한 증상은 기침(66.6%), 코 막힘(51.4%), 콧물(40.9%)등 호흡기 증상으로 확인되었다. 총 10명의 영아에서 혈액배양검사가 시행되었으나 균은 동정되지 않았다. 8명의 영아에서 채뇨백을 이용하여 소변 검사를 시행하였고 2명에게서 농뇨는 없었으나 세균이 배양되었다. 9명(8.6%)의 영아가 경험적 항생제를 투약 받았으며, 투약 기간의 중간값은 2.3일(범위, 1-7일)이었다. 모든 105명의 영아들은 합병증 없이 증상이 호전되었으며, 사망 사례 또한 없었다. 결론: 본 연구에서 코로나19로 진단된 90일 이하의 영아들 대부분이 경미한 증상을 보였으며, 배양 검사가 시행된 환자들에게서 세균 동시감염은 없었다. 이러한 결과는 임상의들이 코로나19 유행기 동안 코로나바이러스 감염이 있는 어린영아들에게 적절한 검사를 시행하고 치료하는 데에 도움이 될 수 있을 것이다.
