This review is focused on the role of ultrasound examination in the management of virus-infected patients. The main aim of the study is to answer the question: is the importance of ultrasound high enough to at least partially replace the examinations using ionizing radiation? Computed tomography, considered the gold standard in lung examinations, or the frequently chosen X-ray method, involves transporting infected patients and putting staff at risk. The USG method allows a relatively quick, easily accessible and non-invasive bedside examination of the patient, which sufficiently shows the nature and extent of lung damage, which is the most crucial for taking the first steps of treatment for a given patient.
