Admission Rate and Factors Associated with COVID-19 Disease in Children Attending the Emergency Department in Hospitals Affiliated to Mazandaran University of Medical Sciences, 2019-2020

 Background and purpose:  Coronavirus (COVID-19) in children includes 1 to 5% of all cases but child mortality due to the disease is rare. The aim of this study was to determine the admission rate and factors associated with Covid-19 disease in children to better understand and control the disease. Materials and methods: In a descriptive-analytical and cross-sectional study 594 samples were selected by systematic random sampling from 1847 children under 18 years of age attending the emergency departments affiliated with Mazandaran University of Medical Sciences. Information was collected from medical records and telephone interviews with parents using a researcher-made questionnaire. Data were analyzed in SPSS V21 applying descriptive statistics, Fisher Exact test, Spearman, Kruskal–Wallis test, and Mann Whitney U test. Results: The mean age of patients was 69.4±71.7 months and 53% were boys. Common symptoms included fever (67%) and cough (29%) and mortality rate was 0.3%. Underlying diseases were seen in 9.3% and seizure was more prevalent (27.3%). Contact with COVID-19 patients was reported by 18.69%. The most common diagnostic method was based on clinical symptoms (80%). Among the children studied, 92.6% were admitted to hospital, of whom 13.5% were admitted to ICU. The mean SpO2 was 96.6% and 13.1% of the patients required respiratory support. The average fear of parents about their child getting Covid-19 was reported to be 5.1. Conclusion: The disease is observed to be mild and moderate in children. Also, severity of the disease and the resulting mortality rate are higher in children with underlying diseases. The most important reason for the delay in referring to medical centers was fear of parents about their child developing COVID-19.
