A Review of a Research in 2021 on Coronavirus Disease (COVID-19) in Pediatric Patients

Abstract

Background Although there were other reviews in 2019 and 2020, this is the first review of research that summarizes clinical features of the children with COVID-19 mentioned in literature in 2021. This paper analyses the findings on COVID-19 infection in children in three countries. Objective The purpose of this paper is to review publications using chest CT scans and chest X-ray findings for children with COVID-19 in 2021. Materials and methods Studies on COVID-19 for articles presenting scan findings in children with COVID-19 have been included in this review. This review focused on articles including 0 < age and age < 18 years using descriptive statistics to identify patterns including duration and several symptoms of the disease, and their relationship with outcomes. Results 12 research articles (n = 6212 children) based on chest CT scans and chest X-ray have been examined. The main results of this review article are as follows: (i) Approximately 1728 (27.81%) of pediatric patients with COVID-19 had normal chest CT scans and chest X-ray images. (ii) The most frequently detected parenchymal lesion was ground glass opacity (GGO) and also bilateral lesions were the common signs of lung lesions. (iii) The lung CT scan findings in children with COVID‐19 were less severe than in adult patients.
