We read with great interest the retrospective observational study in the American Journal of Tropical Medicine and Hygiene by Yasukawa and Minami about the potential use of LUS to evaluate SARS-CoV-2 pneumonia.In conclusion, we strongly recommend the use of LUS in the daily evaluation of COVID-19 patients because, based on our experience, it is inexpensive, quick to perform, more sensitive than auscultation for identification of worsening lung disease, and safer for caregivers.Lung ultrasound findings showed strong correlation with CT findings in terms of localization and degree of lung involvement.
