Up-to-date review of the role of lung ultrasound (US) in early diagnosis of COVID-19 disease associated pneumonia, based on the recent publications at the 2019/2020 pandemic of nCoV-19. Further, highlighting the advantages of lung US over the other imaging modalities as regard early diagnosis, cost and potency of its use as a screening tool in pandemics. The COVID-19 tends to be bilateral with patchy pattern. More frequent in the posterior and inferior fields of the lung. This infiltration is usually irregular and extends to the pleural line. Diffuse B-lines are noticed with air bronchogram sign. Sometimes localized pleural thickening is seen or localized pleural effusion. Occasionally, impaired blood flow in the consolidation patch was detected.
In novel COVID-19 era lung US is a bedside, practical, safe and useful emergency tool for diagnosis. It is operator dependent and this drawback can be avoided by providing proper training.
