The massive raise of COVID-19 cases all over the world is leading to unprecedented pressures on healthcare services. Growing evidence is highlighting that COVID-19 is a systemic condition that requires doctors with multiple expertise. Paediatricians are trained in these skills. Considering the issue of staff shortage that is facing every country in the world, and the complexity of COVID-19, paediatricians may represent an important source of ready and skilled specialists that can quickly translate the paediatric practice in the COVID-19 care. We report our experience by making several parallels between the paediatric clinical practice and clinical conditions described in patients with COVID-19 with particular reference to the use of lung ultrasound in paediatric clinical practice and in that of adult COVID-19 units.
