Objective Data on the prognosis of clinical features of pediatric patients affected by the coronavirus disease 2019 (COVID-19) pandemic is insufficient. This study aimed to examine the clinical, laboratory, and radiology findings of pediatric patients diagnosed with COVID-19.

Methods A total of 81 pediatric patients with a confirmed diagnosis of COVID-19 who were admitted to the pediatric clinics of our tertiary care hospital in Istanbul between March 22 and May 1, 2020, were included in the study.

Results Of the patients, 40 (49.6%) were boys and 41 (50.6%) were girls. The mean age of the patients was 9.3 ± 5.5 years (range: 1 month–16 years). The most common symptoms were cough (28.4%) and fever (25.9%). A total of 26 patients (32.1%) had pharyngeal erythema. There was no significant difference between age groups in terms of symptoms, findings, clinical picture, history of contact, and clinical course (p > 0.001 for each). Abnormal findings were observed in seven (8.6%) patients on chest X-ray, and in four patients (4.9%) on thorax computed tomography. Only three of the patients were hospitalized and all of them discharged with healing.

Conclusion The present study is the most comprehensive study on children diagnosed with COVID-19 in our country, which showed that the COVID-19 picture was mild in pediatric patients, but the signs and symptoms in children were not specific to the disease. Our findings also showed that the rate of asymptomatic infection in children was high and that it was difficult to recognize COVID-19 in children.

 关于受2019年冠状病毒病（COVID-19）大流行影响的小儿临床特征的预后的客观数据不足。这项研究旨在检查诊断为COVID-19的小儿患者的临床，实验室和放射学发现。

方法 纳入2020年3月22日至5月1日期间在伊斯坦布尔三级医院儿科门诊就诊的确诊为COVID-19的81例儿科患者。

结果 患者中男40例（49.6％），女41例（50.6％）。患者的平均年龄为9.3±5.5岁（范围：1个月至16岁）。最常见的症状是咳嗽（28.4％）和发烧（25.9％）。共有26例（32.1％）咽部红斑。年龄组之间在症状，发现，临床表现，接触史和临床病程方面均无显着差异（ 每个p > 0.001）。在7例（8.6％）的胸部X线片和4​​例（4.9％）的胸部X线片中观察到异常结果。只有三名患者住院，所有患者均康复出院。

结论 本研究是对我国诊断为COVID-19的儿童的最全面的研究，结果表明，儿科患者的COVID-19图像较轻，但儿童的体征和症状并非特定于该疾病。我们的研究结果还表明，儿童的无症状感染率很高，并且难以识别儿童的COVID-19。
