Wide spectrum of clinical picture of COVID-19 in children — From mild to severe disease

Children account for a relatively small proportion of laboratory-confirmed SARS-CoV-2 infections. In children, COVID-19 usually has a relatively mild course. However, in rare cases, severe disorders can be observed, and clinical manifestations may differ from adults.PurposeThe aim of this study is to analyse the frequency, clinical picture and outcome of COVID-19 in children based on the experience from the tertiary care centre and regional sanitary-epidemiological office.MethodsWe report a study regarding 106 cases of confirmed SARS-CoV-2 infection cases in PCR from a nasopharyngeal swab (age range 1-month – 17-years). In all cases, history was taken. In children who required hospital admission, physical examination and laboratory test were performed according to clinical indications.ResultsTwelve of the patients required admission to the hospital. The most common symptoms were anosmia and dysgeusia (75%) and headaches (49%) in outpatients and fever in hospitalised children (75%). Three children from the hospitalised group developed a severe course with increased inflammatory indexes. The clinical picture was more severe in younger children from the hospitalised group. Treatment options were regarded individually in all cases.ConclusionOur study is the first tour knowledge regarding the clinical course of COVID-19 in Polish children. In general, the clinical course of COVID-19 was mild with anosmia and dysgeusia as the most common symptoms. However, in hospitalised children, a severe progression of the disease and less typical signs as aplastic anaemia may be developed.
