We report data on pediatric post-COVID syndrome from a Czech multicentric observational study. We enrolled children aged 2-18 years with persisting respiratory symptoms (cough, dyspnoea, chest pain) more than twelve weeks after COVID-19. Medical history, physical examination, lung function testing, chest X-ray and blood tests were performed. In 39 enrolled children, dominant reported symptoms were exercise-induced dyspnoea and cough. On lung function testing, we found abnormal results in less than 15% of children and on imaging in less than 20%. From the analysis of enrolled subjects, we identified four possible post-COVID subgroups: “standard”, “asthmatic”, “sporty” and “polymorphous”. Complete remission of tracked symptoms occurred within a median of 4 months in followed subjects
