Conclusion
According to this first data, the long-term respiratory impact of COVID-19 appears relatively mild with a favorable prognosis in children. Further studies with more subjects and longer follow up are needed. The actual test panel seems effective for the evaluation of structural and functional abnormities of the respiratory tract in pediatric post-COVID.
