Objectives: This study was aimed to evaluate the various demographic and clinical characteristics in hospitalized children with COVID-19 as well as their comorbidities. Methods: This cross-sectional study evaluated a total of 809 hospitalized COVID-19 patients under 18 years of age in the referral university based Ali-Asghar Hospital in 2020. Demographic and clinical characteristics of patients were extracted from the archived records and data analysis was performed using SPSS software version 26. Results: The mean age of patients was 4.1 years and the higher percentage of patients (57%) were male. The most common symptoms of COVID-19 in children were fever, cough, and diarrhea. As well, the most common symptoms in 22.1% of patients admitted to the intensive care unit (ICU) were gastrointestinal (GI) symptoms (79%), fever (62.6%), and respiratory distress (53.6%), respectively. The majority of patients were in the age group less than one year (52%) and mortality rate was 6.3% in total and 10% in children with underlying disease. Besides, the mortality rate of intubated cases was 13 times higher. Conclusion: The findings of present study showed that COVID-19 in children was associated with various clinicopathological manifestations. Underlying disease including respiratory distress, cancer, and kidney disease as well as GI symptoms might be guided predicting the hospitalized cases in ICU. Newborns less than one year of age are exposed to severe COVID-19 infection which is associated with higher mortality rate and it should be given special attention in the early diagnosis and management of the COVID-19 disease.
