Clinically, coronavirus disease 2019 (COVID-19) is associated with a wide range of symptoms, which can range from mild complaints of an upper respiratory infection to life-threatening hypoxic respiratory insufficiency and multiorgan failure. ⋯ In addition to microvascular thrombosis, our results indicate a functional pulmonary vasodysregulation as part of the pathophysiology during the vascular phase of COVID-19. The clinical relevance of autopsies and the integration of radiological imaging findings into histopathological injury patterns must be emphasized for a better understanding of COVID-19.

Point-of-care ultrasound (POCUS) of the lung in patients with COVID-19 plays a key role in the emergency room and intensive care unit. Lung ultrasound is able to depict typical pulmonary findings of COVID-19 and is therefore suitable for diagnosis and follow-up of these patients. ⋯ Lung ultrasound in patients with COVID-19 offers similar performance as CT and is superior when compared to X‑ray in evaluating pneumonia and acute respiratory distress syndrome (ARDS). Lung ultrasound plays an important role in the emergency room and intensive care unit. POCUS reduces exposure to radiation, therapy delays, and minimizes transport of high-risk patients. Differential diagnoses can also be clarified.

The COVID 19 pandemic led to a profound adaptation of the German healthcare system in preparation of a massive increase of SARS-CoV-2-associated diseases. While general practitioners care for COVID patients who are less severely ill, hospitals are focused on the care of severely ill COVID-19 patients. ⋯ For early detection and appropriate treatment of SARS-CoV‑2 infection, PCR is needed. Adjunctive sonographic and radiological examinations allow the treatment of COVID-19 patients to be tailored according to the specific type of pneumonia.
