[Lung ultrasound in patients with symptoms of covid-19].

The SARS-CoV-2 pandemic presents a challenge for healthcare worldwide. In this context, rapid, correct diagnosis and early isolation of infected persons is of great importance. Pneumonia as an expression of COVID-19 is responsible for the most part of morbidity and mortality. Lung ultrasound can provide valuable information about the diagnosis of a COVID-19 pneumonia in daily practice. A normal ultrasound excludes COVID-19 pneumonia. Conversely, finding abnormalities matching with a COVID-19 pneumonia can be useful for isolation policy. Follow up lung ultrasound visualizes the development of the pneumonia and a possible alternative diagnosis can thereby be determined in the event of a deviating clinical course.
